BIODIGESTER SEPTIC TANK DESIGN: 5 Must-Have Features! (Biozone Video)

What are Biodigester Septic Tanks?

Biodigester Septic Tanks are holding and treatment installations used in waste management plants. Waste management is usually a very heated topic in several quarters because it involves the end of many processes which can easily be overlooked.

Waste can be broadly described as what is left after the main use. After something is used, what is left is of no value and therefore it becomes hard to tell people to invest in the proper disposal and management for what is of no use.

The United Nations Environmental Programme (UNEP) defines waste management as the safe and clean disposal or treatment of waste material without harm to the environment. This is where it gets tricky for some people, knowing how to dispose of your waste without harm to soil or water. Proper waste management systems have proper ways to collect, treat, and dispose of waste.

Human waste takes the biggest proportion of all environmental waste products. It is therefore important to know how to dispose of this waste as an environmental conservation process.

This article will discuss biodigester septic tanks and how these installations are a necessity in today’s living setups. It will also educate Kenyans on Blueflame Energy Solutions, which is an organization dedicated to waste management and related services.

Normal Septic Tanks Vs Biodigester Septic Tanks

Many people ask about the difference between normal septic tanks and biodigester septic tanks. A normal septic tank is a storage facility where sewerage wastewater is stored. This facility can be made of concrete or plastic.

These kinds of tanks are mostly found in areas that have no municipal sewerage systems. They hold waste long enough for it to separate into water and solids. The liquids are absorbed into the soil with time while the solids are pumped and taken away for disposal in other places.

Biodigester septic tanks are facilities for waste and sewage management. They hold sewage and waste material waiting for proper treatment and disposal. These septic tanks treat sewage to make it reusable or safe for the environment. Biodigester septic tanks are a modern way of treating waste with the objective of a clean environment.

Blueflame Energy Solutions designs and constructs the Biozone brand of products that include the Biozone biodigester septic tanks. Biozone biodigester septic tanks are currently the number one biodigester septic tank brand in Kenya. This organization has exhaustively researched modern ways of waste management and has developed the best solutions. These solutions include biodigester plants for management of waste and production of biogas, chemicals, bacteria and enzymes used in the biodigesters, appliances and accessories related to biodigesters and all required biodigester maintenance services.

The differences between normal septic tanks and Biozone biodigester septic tanks appear in terms of costs, benefits and environmental care as briefly explained below.

I. Biodigester Septic Tank Costs

While the initial cost required for the installation of biodigester septic tanks may be higher compared to normal septic tanks, the long-run maintenance costs will be lower. This can mainly be attributed to the frequent need for exhauster services related to the normal septic tanks.  Normal septic tanks may need to be exhausted a number of times per year once they fill up while Biozone Biodigester Septic Tanks will need to be exhausted once in several years depending on the usage and capacity.

II. Biodigester Septic Tank Benefits

Normal septic tanks only hold waste material as it awaits further disposal and management while biodigester septic tanks hold waste, treat waste, and reuse waste. Biozone biodigester septic tanks can produce reusable water that can be reused for irrigation.

III. Biodigester Septic Tank Environmental Care

Normal septic tanks are prone to frequent overflows which become hazardous to the environment while Biozone biodigester septic tanks don’t experience overflows. Also, normal septic tanks usually release unpleasant odors to the environment while biodigester septic tanks don’t release any odor.

As it can be seen from the above points, Biozone biodigester septic tanks are more useful than normal septic tanks. For more comprehensive benefits of biodigester septic tanks, look at the advantages section of this article.

Converting Septic Tanks into Biodigester Septic Tanks

Normal septic tanks can be converted into biodigesters by restructuring them and introducing the right chemicals made of bacterial cultures and enzymes. Remember the work of biodigesters is to break waste material into gas, water, and sludge.

Once the biodigester enzymes and bacteria have been introduced into a normal septic tank or a pit latrine, they will quickly break the solid waste into gas, water, and slurry. Since the initial design cannot adapt to make use of the bi-products, the gas is released into the environment in very small quantities while the water sips into the soil. The little sludge left will settle at the bottom.

The main aim of converting normal septic tanks into Biozone biodigester septic tanks is to save on the costs associated with normal septic tanks. This conversion will make sure that your new septic tank will not fill up and bad odors are eradicated.

However, it is difficult to convert a normal septic tank into a biodigester for gas production. That is because household waste including bathroom and kitchen sink wastewater is not optimal for biogas production.

Types of Biodigester Septic Tanks in Kenya

Most biodigester septic tanks are constructed from either concrete or plastic. Blueflame Energy Solutions also constructs the same types of biodigesters;

I. Plastic Biozone Biodigester Septic Tanks

These models are cheaper and easy to make and install. They are especially suited for small to medium use. They come readily designed and only the fitting is done on-site. Plastic biodigesters are more common in households and are not usually used for other purposes apart from waste management. Due to the nature of the material, they are not long-lasting as plastic is more prone to wear and tear than other materials used to make biodigesters.

II. Concrete Biozone Biodigester Septic Tanks

This kind of biodigester septic tanks from Blueflame Energy Solutions are concrete made and are suitable for small, medium and large-scale users for waste management. They are also best used for water recycling. They are a little costly than the plastic ones but they are more durable. They can be used in single households, apartment blocks, housing estates, institutions, municipal areas among other settings.

Biozone Biodigester Septic Tanks Lifespan

Biozone biodigester septic tanks’ lifespan depends largely on the material used to make them and maintenance done on them. The least time is 15 years and with regular checkups, the lifespan goes even up to 50 years. Plastic biodigesters are less durable than concrete ones, and therefore for a long-lasting biodigester septic tank, it is advised to go for the concrete one.

How Biodigester Septic Tanks Work

Biozone biodigester septic tanks break down waste matter into water, carbon dioxide, and methane gas (biodegradation). When wastewater comes into the tank, special bacteria in the tank feed on it converting it into water, gas, and sludge. The sludge settles down and continues decomposing gradually while water and gas can be collected for other uses.

Biozone biodigester septic tanks have three crucial parts, grease interceptor, biodigester tank, and spillage drain.

Note that wastewater is made up of blackwater and greywater. Blackwater comes from the toilets (water in contact with fecal matter) while greywater comes from kitchen sinks and bathrooms.

The greywater contains harmful substances like oils, grease, and detergents. It goes through the grease interceptor to remove these substances after which the now clean water goes to the spillage drain (soak pit) for further treatment from where it can be used for irrigation.

The blackwater goes into the biodigester tank where bacteria and enzymes are introduced to feed on the solid part while cleaning the water. The solid part settles into the bottom from where decomposition takes place producing water and gas. The water goes to the soak pit while the gas can be vented into a special chamber for further conversion into cooking gas or released into the atmosphere.

Note that only Biozone biogas digesters can be used to produce enough gas which can be used for domestic purposes. Biozone biodigester septic tanks produce methane gas in small quantities which is released into the environment as it cannot be used for any other purposes.

The soak pit can be perforated to allow the water to soak into the soil or the water can be drained using pipes to be used for irrigation. This water is rich in nutrients which make it good for plants and vegetables. However, this water is not fit for domestic purposes or animal use because it still contains some trace minerals harmful to humans and animals.

Biodigester Septic Tanks in Kenya

Kenya is still a developing economy and therefore some aspects like a good sewerage system are still not up to the required standards. Not many urban areas have a functional sewage system and the ones available are overstretched. With population growth not encompassed in the sewage facilities available, the existing facilities are always broken down or congested. Many towns’ sewage systems are blocked or leaking which results in outbreaks of diseases and bad odor, especially in the informal settlements.

The few exhauster services available have also become too expensive for the majority of the people. A lot of people opt to build new sewage facilities after the existing ones fill up instead of the exhauster services. This has become a challenge especially in urban areas where space there is in increasing shortage.

That is why, Blueflame Energy Solutions as the leading waste management and treatment organization in the country came up with biodigester solutions under the brand name “Biozone” to keep the waste management menace at bay. We developed biodigester septic tanks while offering to upgrade the existing ones to achieve bio digesting capabilities. This move has greatly reduced and improved waste management and disposal problems.

Blueflame Energy Solutions offers the chance to new and old buildings to be self-reliant in terms of waste disposal. This strategy together with the gradual rehabilitation of many waste management facilities across urban areas has greatly eased the burden on the sewage systems available hence creating a cleaner environment.

With the need for exhauster services greatly reduced, Blueflame Energy Solutions also developed ideas to better use waste instead of only disposal. The organization developed biodigester septic tanks with the capability of producing clean recycled water which can be used in many ways, for example, irrigation. The methane gas from Biodigester septic tanks is in small quantities and is released into the atmosphere.

Biozone biogas digesters on the other hand produce enough methane gas (biogas) to be used for cooking or lighting.

Biodigester Septic Tanks Construction

Due to the increasing need for proper and practical waste management methods, biodigester septic tanks have become part of the structural design in new construction plans. With the increase in demand for these septic tanks, many organizations providing this service have also developed. This has left many potential clients confused about the provider to choose.

Blueflame Energy Solutions has proved to be the best waste management and disposal service provider in the country. This is largely due to the pocket-friendly services they offer, the scientifically developed solutions they offer, and the great customer care they provide.

Biodigester septic tanks suppliers

The construction of a biodigester septic tank does not solve all the problems of waste management. The service provider must ensure timely maintenance and regular checkups to ensure that the facility is functioning optimally.

This is what separates Blueflame Energy Solutions biodigesters from others. Once we supply and constructs a tank, we will keep periodical consultations with clients and give proper guidance on the proper use of the biodigester septic tanks to ensure the best results.

This is also applicable to those biodigester installed for gas production. This process needs timely additions of waste and bacteria to ensure constant production of gas. The number one expert on the installation of biodigester tanks for cooking gas production in Kenya is Blueflame Energy Solutions.

Biodigester septic tanks dimensions

How to make a biodigester septic tank in Kenya remains a puzzle to many people. That is because many people still associate these tanks with heavy construction and installation needs.

This is not the case. Any household can have a biodigester constructed and installed. That is because the size and dimensions of the biodigester septic tank will depend on the needs of every particular client.

This means that before the construction and installation of biodigester septic tanks, clients will be provided with a plan of the plant. It will depend on the amount of waste to be disposed of and the kind of by-products required if any.

Biodigester septic tanks to produce gas will be different from those to dispose of waste. This means the needs of every client should be clearly stated before the construction and installation of biodigester septic tanks.

How deep are biodigester septic tanks?

This is also a question in many people’s minds. Blueflame biodigester septic tanks are mostly constructed or installed underground with only a small part of the facility visible. This ensures that in case of damage or spillage, the waste can be easily contained underground. It is also important to note that the biodigester cannot be fully buried underground since it has to allow access in case of maintenance or repair.

The proper practice is to allow at least 7 inches of the biodigester above the ground while the rest is underground. The depth the biodigester goes underground will depend on the size of the tank. It is important to know the measurements of your tank before digging the hole or trench.

Biozone Biodigester Septic Tanks

Blueflame biodigester septic tanks can be broadly classified into two main types, anaerobic and aerobic biodigesters. 

I. Biozone Anaerobic Biodigester Septic Tanks

These biodigesters contain chambers that are tightly sealed and operate without oxygen. They produce gas and digestate as by-products. The gas can be used domestically upon further processing depending on the amount produced while the digestate is diluted to be used as fertilizers. Biozone anaerobic biodigesters are better for farms because they specialize in animal waste.

II. Biozone Aerobic Biodigester Septic Tanks

These biodigesters use oxygen as part of the process of breaking down solids. They produce water and sludge as byproducts but not gas. They are more effective for waste management but are not optimal for biogas production.

Apart from the above-mentioned main categories of Biozone biodigester septic tanks, they can also be broken down further into mechanical and non-mechanical biodigesters;

I. Biozone Mechanical Biodigester Septic Tanks

Biozone mechanical biodigester Septic tanks use additional machines to further purify waste in-order to obtain cleaner by-products. They are of two types, ASBR Wastewater Treatment biodigesters, and SBR Wastewater Treatment biodigesters. They are mostly used in water treatment and purification processes.

II. Non-mechanical biodigesters

Biozone Non-Mechanical biodigesters don’t have additional machines for further purification and only use the bacteria introduced to break down solids. Their by-products are not as pure and they are mainly used in homes for normal waste management with no need for the by-products. They are Biozone Biodigester Systems, Biozone Septical Biodigesters, and Biozone Bio Latrines.

Below is a list of specific biodigesters designed and supplied by Blueflame Energy Solutions under the Biozone brand. They fall in either of the categories mentioned above.

I. Biozone Bio Latrines.

Normal pit latrines use a pit to store waste which is then emptied by exhausters once it fills up. In the rural areas, since the exhausted services are not available or are expensive, people opt to build new pit latrines after filling up the old ones.

Bio latrines solve this problem by using biodegradation principles as used in biodigesters. Special bacteria available in bio latrines means that the pits don’t fill up hence reducing the costs related to exhausted services building new ones.

Bio latrines are suitable to areas with high water tables where digging up deep pits is impossible without breaking the water table. They are also effective in areas with water scarcity since they use very little water, unlike other biodigesters that use water as part of the process. They will still be suitable for congested areas like slums since they need little space to build and they are easier to maintain.

  1. Biozone Biodigester Systems. 

These are the normal biodigester tanks found in households and business settings. They manage waste by breaking it down into gas, water, and sludge. The Blueflame biodigesters are different from other biodigesters in the market in that:

  1. They can be custom made to fit specific client needs as compared to others that usually come ready-made therefore offering no flexibility in terms of size and design.
  2. They come with four chambers for a better breakdown of solids as compared to others that have single chambers which makes them take long in breaking down solids.
  3. They have bigger inspection points and manholes as compared to others that have small inspection points hence making routine maintenance and repair very difficult.

III. Biozone Septical Biodigesters.

They are an improvement to the Biozone Biodigester Systems. These models have an added fixed-film reactor (FFR) which greatly improves the solids breakdown process. The FFR fastens the process and reduces the amount of sludge left.

IV. SBR Wastewater Treatment Plants.

Sequential Batch Reactors (SBR) are used to treat sewage water for households and medium-sized organizations. The water produced is free from nitrogen and carbon making it suitable for irrigation. The water may also be discharged into non-sensitive water sources since it has been highly purified.  The water goes through three stages of purification before it is used or discharged to other water sources.

The first chamber separates water from solids before moving to the second chamber where the water is thoroughly purified through mechanical processes and fully separates any remaining sludge with the water. The sludge settles at the bottom while the water goes to the third chamber for disinfection and chlorination.

The water is then fed into the last holding chamber from where it can be used or released. The sludge is then moved to the first chamber for the process o begin again.

V. ASBR Wastewater Treatment Plants.

This is an advanced form of the SBR treatment. The wastewater here also moves through three stages before it is safe for discharge. In the first chamber, it is separated from solids which settle at the bottom and are continually broken down by anaerobic processes. The water then is moved to the second chamber containing Aeration Sequential Batch Reactors (ASBR) which introduces oxygen into the water to enhance the purification process.

The breakdown in this chamber is finer due to the introduction of oxygen. The water is moved to the third chamber where it is disinfected and treated before it goes to the fourth tank where it is held ready for use or discharge to the environment.

Note that both the ASBR and SBR treatments incorporate special mechanisms into the purification and treatment process and therefore will need constant repairs and Maintenace due to wear and tear as compared to the non-mechanical biodigester septic tanks which need minimal repairs and maintenance.

Chemicals, Bacteria, and Enzymes Used in Biodigester Septic Tanks

Blueflame Energy Solutions supplies several bacterial formulas, enzymes, and chemicals used in biodigester septic tanks. These bio cultures can be classified into those used in wastewater management, solid waste management, and general disinfectants. Many people ask which bacteria are used in biodigester septic tanks, and to answer this, the following is a breakdown of where and how several bio cultures are used.

I. Bacteria, chemicals, and enzymes used in solid waste management.

These are the bacteria and enzymes used in the biodegradation of solid waste into water, gas, and sludge. They are common in pit latrines and biogas digesters. There are two main bio cultures supplied by Blueflame Energy Solutions for solid waste disposal:

  • Bioclean BFB – This formula is derived from the residue in sugar processing. It is the left-over part after sugar pressing. it is rich in nutrients and organic carbon which is helpful in the breakdown process of solid waste.
  • Bamoyeast BFB – This enzyme helps in fine-breaking sludge and cleaning the water. It can be used in both aerobic and anaerobic processes. It also reduces odor in effluent and while changing color from dark brown to clear blue. It is especially useful where the water is to be released to the environment as it purifies and makes it safe for irrigation or discharge.

II. Bacteria, chemicals, and enzymes used in wastewater treatment.

Water is a by-product of all Biodigester septic tanks and it needs to be cleaned further before it is safe to be re-used or discharged to the environment. The odor from sewage facilities is also a big headache for environmentalists and that is why Blueflame Energy Solutions has developed several types of chemicals and bacteria to help in cleaning water and reducing odor.

  • Environzyme BFB. It reduces odor from biodigester septic tanks and also causes the sludge to settle down completely helping in changing the watercolor.
  • Septoclean BFB. It is used in cleaning bathrooms to reduce odor. It contains enzymes that break down fats, detergents, and oils from bathroom water. It is also useful in dissolving things like paper which can cause blockages in the biodigester septic tanks.
  • Septozyme BFB. It reduces carbon in wastewater hence making it safe for the environment. It also reduces odors in wastewater.

III. Biodigester septic tanks chemicals and disinfectants.

These are the chemicals developed by Blueflame Energy Solutions to aid in cleaning water for domestic and household use.

  • Chroline 65. It is used to clean drinking water. It can also be used to clean swimming pools and fishponds. It is packaged in 1Kg, 5Kg, and 20Kg and it is advisable to consult Blueflame Energy Solutions to know what amounts to use to avoid poisoning caused by excessive use.
  • Hydrated Aluminium Sulphate. This is a disinfectant used to aid the filtration of water. It removes particles from the water making it clear and less turbid. It is packaged in 5Kg, 20Kg, and 50Kg packs.

Biodigester Septic Tanks Appliances and Accessories

These are the supporting appliances found in septic tanks or normal tanks to aid in the cleaning of water. They can also be found in other water-holding facilities and swimming pools. They are air blowers, filters, and filtration media. The following are appliances and accessories designed and supplied by Blueflame Energy Solutions:

  1. Air Blowers. These are the mechanical equipment used in providing oxygen in the biodegradation process or wastewater treatment. Since oxygen is a vital part of the aerobic degrading of waste, then these air blowers are a must in all aerobic biodigester septic tanks. They are of two types, Diaphragm air blowers, and Regenerative air blowers.
  2.  Diaphragm air blowers. These are single-phase AC-powered blowers with an airflow capacity of between 60m3/h and 200m3/h. They operate on low power and are thermally protected in case of overheating. They are weatherproof, easy to maintain, and noise-free which makes them ideal for wastewater management. They are mostly used in the aeration process in biodigesters and for oxygen supply in fish ponds.
  3. Regenerative air blowers.  Also known as ring blowers or vacuum pumps, these blowers are also AC powered with an air range between 70m3/h to 2480m3/h. They are made of cast aluminum and are fully insulated. They are maintenance-free machines and are also quiet making them ideal for biodigester septic tanks. They can also be used in aquaculture to provide fishponds with oxygen.
  4. Filters. They are non-corrosive fiberglass strong and durable tanks that allow 360 degrees of rotation for easier installation. The material is also AV resistant making them suitable for biodigester septic tanks. They can operate with all the filtration media supplied by Blueflame Energy Solutions.
  5. Filtration media. These are the materials used in filters for filtration purposes. They are Glass media, Silica Sand media, and Activated Carbon media.
  6. Glass media. Packaged in 25Kg bags, this media provides cleaner, clear, and healthier water. It is superior to all other filtration media. It is ideal for drinking water treatment and swimming pools.
  7. Silica Sand media. They are used for filtering and purifying water that has visible particles. Packaged in 50Kg bags, this media is suitable for wastewater treatment, power generation, and swimming pools.
  8. Activated Carbon media. These are also known as charcoal filters in that it is practically perforated charcoal used to filter chemicals from water. It is used where water has high levels of chroline, odor, and doesn’t taste good. It is packaged in 25Kg bags.

Blueflame Energy Solutions Biodigester Septic Tanks Services

These are the various services offered by Bluflame Energy Solutions both for solid waste management and wastewater management.

I. Biogas digesters maintenance and rehabilitation.

Biodigesters designed for gas production require periodic checkups to ensure that there is a steady production of gas. The gas production process can easily stop if not closely monitored and the right corrective actions are taken whenever necessary.

Rehabilitation of a stalled plant is more costly than maintenance and it is, therefore, necessary to have Blueflame Energy Solutions constantly checking on your plant. The following are the services offered for routine maintenance:

  • Training on the right material for biodigesters and ensuring that the material is constantly supplied for the constant production of gas.
  • Checking on the bacterial activities in the plant and advising on when to add the required enzymes and bacterial especially for anaerobic biodigesters.
  • Slurry analysis to ensure that it remains optimal for gas production.
  • Regular slurry PH testing.
  • Regular inspection of gas pipes and gas valves and replacement whenever necessary.
  • Inspection of water traps for leakages which may make the gas moist hence incombustible.
  • Removing sludge when it becomes necessary.
  • Cleaning of stoves and lumps which may be blocked by other gases produced during gas production like carbon dioxide and sulphur dioxide.

II. Conversion of septic tanks to biodigester plants.

As it has been earlier observed, Blueflame Energy Solutions can convert normal septic tanks into biodigester septic tanks. This is mainly done by reconstructing the old septic tanks introducing the right enzymes and bacteria combination into the septic tanks.

The introduced bio cultures will then feed on the waste hence the process of biodegradation. The reconstruction involves the introduction of extra separate chambers, one of which will be used to anaerobically treat waste hence an improved waste treatment facility.

III. Supply and application of enzymes and bacteria.

Proper waste management systems require the regular introduction of special enzymes and bio cultures which are essential to the biodegradation process. Knowing the right dosage, combination, and timing of application can be hectic for a lot of people.

This is where Blueflame Energy Solutions comes in. The organization will not only supply the necessary bio cultures but will also supply the required experts to do the application and monitoring of the process.

IV. Biodigester septic tanks maintenance and rehabilitation.

Although biodigester septic tanks are meant to ease the waste management and disposal problem facing people, the facilities need constant periodical checks and repairs which may affect the smooth operations of the septic tanks. Blueflame Energy Solutions has the experts equipped to deal with such routine repair and maintenance required.

The indigestible scum will gradually build up hence requiring safe removal and disposal which is handled by this organization. This organization can also rehabilitate abandoned biodigester septic tanks and make them operational once again hence saving clients costs associated with establishing new ones.

V. Drainage maintenance.

Drainage systems are very crucial in the operations of biodigester septic tanks. These are inlet and outlet systems involved in the waste treatment process. This piping will be subject to wear and tear and therefore need regular cleaning and maintenance. These regular checkups are important since they can prevent blockages which will be very unpleasant.

Blockages will cause back-flow of sewage water into households or unnecessary overflowing of septic tanks. This can be a cause of diseases like cholera hence a health risk to people. To prevent this, Blueflame Energy Solutions provides experts who regularly inspect thIS piping for any necessary cleaning and repair.

VI. Wastewater treatment and consultancy.

Production, processing, or manufacturing plants produce a lot of waste and wastewater due to the nature of their operations. These operational waste by-products need proper disposal to ensure the least environmental impact. That is why environmental compliance certificates are issued by governmental environmental agencies.

Blueflame Energy Solutions provides consultancy services to make sure that disposal requirements are properly observed for successful environmental compliance certificates registration. This is done by reviewing the existing wastewater disposal facilities, designing new disposal facilities, and assessing the environmental impact of wastewater discharged.

Industries Served by Biozone Biodigester Septic Tanks

These are the industries whose operations need biodigester septic tanks for waste disposal. They are divided into commercial buildings, domestic buildings, and institutions.

I. Commercial buildings.

Biozone biodigester septic tanks for commercial buildings are installed to serve business premises, large residential estates and manufacturing factories. Most of these premises have not been connected to any sewage systems and use septic tanks for their waste management. Blueflame Energy Solutions offers Biozone Biodigester Systems which can handle such large amounts of waste. These systems eliminate the need for constant emptying of septic tanks and pit latrines.

Blueflame Energy Solutions can also modify or upgrade septic tanks into biodigesters. This is done through reconstruction and by introducing the right enzymes and bacteria which digests waste into little sludge and water.

II. Domestic buildings.

Biodigester septic tanks for domestic buildings help many households especially in the rural areas and informal settlements which still use pit latrines and septic tanks for waste disposal. The Biozone biodigester septic tanks offer a solution to these waste management nightmares. These are specially designed smaller biodigester septic tanks fit for domestic houses. All waste from toilets and bathrooms is directed to these septic tanks where it is treated and released to the environment with no harm. These Biozone biodigesters require little or no maintenance which is a cost-saving means of waste disposal.

III. Institutions.

Biozone biodigester septic tanks for institutions are installed in schools, colleges, universities, jails, churches and similar establishments. Most of these institutions experience waste disposal problems due to the huge amounts of waste produced every day.

Blueflame Energy Solutions designs and supplies Biozone biodigester septic tanks and systems fit to serve any number of people. The systems supplied to these organizations substantially lower waste disposal costs for these institutions as well as produce water and energy (gas) which can be reused. These organizations are also offered maintenance services by Blueflame Energy Solutions. This helps the institutions to make waste disposal and management hustle-free.

Biozone Biodigester Septic Tanks Price in Kenya

How much is a biodigester tank in Kenya? Biozone biodigester septic tanks are designed and tailor-made to suit different client requirements. Apart from the standard domestic 400-liter design, every other design will depend on the specific needs and instructions of the client.

Note also that biodigester septic tanks are of different types (aerobic/anaerobic, mechanical/non-mechanical) and will have different capacities. These two aspects of type and capacity are what will largely determine the price of the Blueflame biodigester septic tanks.

Whatever special needs or requirements you may have, Blueflame Energy Solutions will have or design a biodigester to suit you.

Advantages of Biodigester Septic Tanks

These are the benefits of biodigester septic tanks over normal septic tanks and pit latrines.

  • Costs saving. Normal septic tanks require regular exhauster services which are expensive while biodigester septic tanks do not require such services.
  • Decreased foul smell. Biodigester septic tanks have very little or no odor at all since almost all waste is broken down while normal septic tanks tend to be smelly.
  • Little maintenance costs. Biodigester septic tanks require little or no maintenance as compared to normal septic tanks which need constant maintenance since they hold bulk waste material for long periods hence increasing wear and tear.
  • Space requirements. Bluefalme biodigester septic tanks require little space to set up as compared to normal septic tanks. This is because biodigesters hold waste for short periods before full treatment and biodegradation while normal septic tanks have to hold a lot of waste until they are emptied by exhausters.
  • Biodigester septic tanks produce by-products like water and gas which can be reused for other services while normal septic tanks have no byproducts. The water from biodigesters can be channeled for irrigation services since it is rich in plant nutrients.
  • Decreased environmental pollution. Biodigester septic tanks break down all organic waste and the by-products released to the environment are not harmful. Normal septic tanks on the other hand need to be exhausted and their contents disposed of somewhere else. These secondary disposal sites are big environmental pollutants. A case example is the Ruai sewage disposal site in Nairobi which has continually brought harm to the surrounding environment.
  • Overflow risks. Biodigester septic tanks offer zero risks of overflowing, but normal septic tanks are prone to overflows since it is added to tell when they need exhausting. This is a health risk particularly in areas where flooding usually occurs. Many hygiene-related illnesses like cholera have been known to be more prevalent in areas with poor drainage and sewage systems.

Disadvantages of Biodigester Septic Tanks

  • Bioculture additions. Biodigester septic tanks need periodic additions of the bacteria and enzymes that make the biodegradation process possible, while normal septic tanks do not require such additions.
  • Material disposed of in biodigester septic tanks needs to be organic otherwise the biodegradation process will not be possible.
  • The design and setup of biodigester septic tanks require a high level of expertise and technical know-how as compared to normal septic tanks.

Note that although biodigester septic tanks may not be perfect, the advantages totally outweigh the disadvantages and it is therefore highly recommended for people to adopt biodigester systems as the way to safe and environmentally friendly disposal and management of waste.

Biodigester Septic Tanks Design

The wishes, needs, and requirements of different clients will always be different, and therefore the final designs on the kind of biodigester septic tank to be installed will be different. It is always advisable to have a sketch or general layout for the kind of biodigester required. This helps the designers at Blueflame Energy Solutions in designing the best for each client.

Some factors which will be considered in the final design are:

  • Capacity. Biodigester septic tanks for large industries are different from those of households and domestic buildings.
  • Type. There are aerobic and anaerobic biodigesters and also mechanical and non-mechanical biodigesters.
  • Use. Biodigester septic tanks used for gas production are different from those whose primary objective is to dispose and treat waste only.

Whatever the design preference of a client will be, the final design will be handed to the client in a pdf file first before any construction work begins. This is to ensure that the clients’ needs and specifications have been met and addressed. It also offers the client the chance to suggest any corrections to be made. The final design will therefore be a total agreement between the client and Blueflame Energy Solutions. Prospective clients can also download general designs from the website which will be improved upon to the specific requirements of the client. This saves time in the design period which can be used for a speedy installation of the biodigester.

Why choose Biozone Biodigester septic tanks over other biodigesters

Many companies offer biodigester septic tanks and services in Kenya but Blueflame Energy Solutions will remain the preferred choice for many and this is why their products and services are superior to all others:

  • Size- Blueflame biodigesters have no fixed size and the final size will depend on the number of people to be served and the final agreement between the client and the company. Proper sizing ensures that the waste retention time is minimized hence allowing for full waste treatment.
  • Multi-chambered- Blueflame biodigester septic tanks have four chambers which make the biodegradation process easier and thorough. This makes the amount of sludge produced by Blueflame biodigesters the least compared to other biodigesters.
  • Large manholes- These are the inspection points that are used in case repairs are necessary. Blueflame biodigesters come with large manholes which makes periodical repairs and maintenance easy.
  • Fitting downpipes- These are the pipes that connect the different chambers of the biodigesters. They ensure that only water moves from one chamber to another without disturbing the settled waste.
  • Membrane bioreactors- These are extras that help in the eventual purification of water. For Blueflame biodigesters, the membranes are placed between the third and fourth chamber and also at the outlet to ensure great purity of water. This is why Blueflame biodigesters’ final discharge is over 90% solids-free.

With the above-mentioned advantages, it can be seen why Blueflame biodigesters are the best in Kenya.

FAQs About Biodigester Septic Tanks

Before the installation of biodigester septic tanks, there are a lot of questions that clients often ask. The most frequent ones will be answered below.

Does shower water go into biodigester septic tanks?

Yes. Shower water goes into the biodigester septic tank and it is a crucial element in the biodegradation process. It is advised that if there is not enough water in the biodigester septic tank, the water should be added manually.

What can be put in biodigester septic tanks?

Not every kind of waste can be processed by a biodigester. The biodegradation process only works for organic waste, and inorganic material does more harm to the biodigester than good. Sanitary pads, condoms, and cigarette butts are some of the materials that are non-biodegradable and should not be put into biodigesters. Also, note that some detergents may be harmful to the bacteria in the biodigesters and so they should be avoided. To get the best information on the materials to use and avoid in biodigesters, contact Blueflame Energy Solutions.

Do heavy rains affect biodigester septic tanks?

Yes. Biodigesters need a drainage system to empty the water which is a by-product of the biodegradation process. This water may have a soak pit or it may be drained using pipes and then released into the environment. Where the water uses a soak pit, heavy rains will cause the soil to soak a lot of water hence making the water from the biodigester buildup. This may easily cause the biodigester to overflow which is a health risk.

For what purposes can water from biodigester septic tanks be used?

Water from biodigesters is rich in nutrients which are very good for plants. Therefore, it may be used for irrigation. However, there are the SBR and ASBR wastewater treatment tanks from Blueflame Energy Solutions which can be used to further purify the water to make it useful for domestic purposes like cooking, flushing toilets, and washing clothes.

How far from the house should biodigester septic tanks be constructed?

This will depend on the nature and size of the biodigester. For domestic purposes, 2 meters to 50 meters from the house is the standard distance, while for heavy commercial and institutional use the distance is between 100 meters and 300 meters. Note the further away the biodigester is, the more costly it will be to set up and operationalize.

Do biodigester septic tanks need to be connected to a sewage system?

No. When you have a biodigester, it is not necessary to be connected to a sewage system. This is because a biodigester does all the work a sewage system can do and more.
