Wastewater Definition Water resulting from our everyday life activities like domestic, industrial, agricultural, medical and transport activities is called wastewater. Water can only become waste water if its quality, composition and temperature are changed. It is also defined as a complex mixture of both organic and inorganic materials. It can be in two categories; Gray […]
What are the three stages of sewage treatment • Primary Treatment: This sewage treatment involves removing floating solids by gravitational settling. The large solids are screened first then grease and scum are removed. After this, sand and other coarse substances are removed by grit chambers. The grit is then removed and screened. Wastewater is then […]
Drainage Meaning (What Is Drainage) This is the disposal of excess water from a surface. In plants, good drainage is important. This is because it ensures all nutrients are present. However, there are some plants that thrive in swampy areas. Natural drainage occurs all by itself through the soil. Hence, it is responsible for soil […]
Biogas Generator This is a system of motors used to convert biogas into electricity. Biogas is a mixture of flammable gases, mostly methane. It also contains carbon dioxide that forms anywhere there is an anaerobic decomposition of organic matter. This could be in the water, in a landfill, or in the guts of animals, including […]
Bio-gas Digester This simply means a tank that biologically digests organic material to produce bio-gas. However, most people think of it as a tank that digests organic material anaerobically without oxygen. The organic material produces methane gas which can be used for cooking, lighting, heating, etc. Bio-digesters can be installed for simple household uses. It […]
A biodigester septic tank is a waste and sewerage management and treatment system. It can be of great use in both residential and commercial buildings. Unlike the normal septic tanks, the solid and liquid wastes are treated so that they can be used in other ways. A biodigester septic tank is a one-time waste control […]
Septic tank design should be very good and most importantly accurate. This ensures its effectiveness and most importantly its durability. A septic tank is a chamber which helps manage and control wastewater. This is as a result of bioactivities inside the tank which convert solid waste to liquid. Most septic tanks just separate the solid […]
Septic Tank Definition A septic tank is basically an underground bioactive chamber. It is made of concrete, fibreglass or plastic. It intends to control, manage and most importantly treat waste material. The decomposition is based on anaerobic bacterial reaction. As a result, solids and organics materials reduce to liquid. The water leaves it through the […]
What is Biomass This is a renewable source of energy that comes from organic materials. You can convert it into other forms of energy like biogas or you can just burn it directly. Examples of biomass include: Wood waste – it produces heat for buildings, industries and also generates electricity. Agricultural crops and waste materials […]
What are Biogas digesters Biogas digesters are devices that carry out anaerobic fermentation on organic waste to release methane gas and produce biogas. The most common types of biogas digesters are wet biodigesters. This is because they digest liquefied manure on farms. Most people prefer wet bio-digesters in removing methane from manure so they can […]
