FAQ

From 4M³ or 4000 liters .Based on the challenges faced in our past constructed biodigesters, our engineers and experts concluded that 4m 3 is the best minimum size as it allows adequate retention time for complete sewage treatment. Essentially, sufficient time (retention time) is required for separation of settleable solids from water and flotation of scum.

NO. Our biodigesters are either rectangular or cubical. The goodness with our system is that we’re flexible with the available space within building, apartments or premise

Our biodigesters construction has been divided into four project phases: Excavation phase (which takes between 2 to 7 days), construction phase (which takes 7 days), curing phase (which takes 7 days) and Finishing phase (which takes up to 7 days). The whole project construction takes up to 4 weeks. We always endeavor to deliver quality construction work following the requisite construction standards to ensure that our clients get value for their money.

YES. Our soakage is 3 to 4 times bigger than biodigesters. In our years of experience, we have come to realize that biggest headache for biodigesters’ use is the soakage (soak away).
Essentially, the bigger the soakage, the better. The dimensions of our soakage is 6m by 1.2m by 2m which gives a volume of 14.4m 3 against biodigester volume of 4m 3 . In addition, we minimize blockage through even distribution of water along the horizontal length of the soakage using uniformly perforated pipe hence prevent possible saturation and blockage of certain small sections of the soak away. Besides, it is made of hard course materials to support the soakage walls against collapsing and ensure smooth water infiltration.

It is not advisable for a biodigester to be installed under a living house to avoid inefficiency and discomfort caused during inspection and maintenance. However, it can be done under raised structures such as a store, houses for domestic animals such as chicken house, etc.

i. Population
ii. Availability of space
iii. Location: determines soil type
iv. Water table
v. Effluent Use
vi. Budget

NO. There is no need to exhaust biodigesters after six months since the design of our biodigester includes a four-chamber system which provide ample space and retention time for effective digestion of organic solid waste hence continuously keeping the levels in the digester low.

i. Grease traps cleaning and servicing
ii. Soakage inspection
iii. Drainage inspection and unblocking if blockage is traced
iv. Removal of indigestible and scum trapped in the first chambers
v. Checking, servicing and repairing all the membrane and fixed film if repairable
vi. Dosing of biodigester with the recommended enzymes and bacteria, as deemed fit.

The biodigester septic tank is based on biodegrading processes. This is the breaking down of organic waste matter into carbon dioxide, methane and water. The bacteria in the tank feed on the organic wastewater and the dark water as they come in. As a result, they become water and gas. The effluent takes about 2 weeks to decompose. After the water treatment is complete, it leaves through the outlet to the soakage for filtration into the surrounding soil. The biodigester uses the displacement principle. The amount of wastewater flushed into the system displaces the equivalent volume from the biodigester tank to the soak drain.

The Biozone biodigester is rectangular or cubical in shape depending on the available space. The arrangement of components includes grease trap just after the kitchen, a four chamber digester of 4M³ minimum size (variable depending on population size and available in multiples of 4) and soak away.
