We hereby seek to introduce our product, Biofil Toilet Digester, a unique technology to manage sludge.
Biofil Toilet Digester is an innovative on-site waste water treatment option that offers integrated treatment of sewage in a manner that poses minimal risk to the environment and public health, and the opportunity of sustainable economic returns on natural biological treatment of waste in the long term.
It is a technology that works by providing an enclosed environment for natural process of aerobic decomposition of feces including toilet paper and degradable materials. The digester is constructed as a living filter where oxygen inflow into the vault allows the seeds (bacteria, fungi, macro-organisms) within to degrade solids at the top layer aerobically and liquid are filter into the lower layers before being directed out of digester through a pipe into constructed drain field or collected and treated for reuse. This process is called RAB system;
Rapid separation of solid and liquid
Aerobic decomposition of solid
Bio- filtration of waste water
This is the same type of environment in forest where wildlife droppings are decomposed and converted into valuable nutrient for vegetation.
The Biofil Toilet Digester can be applied to replace the septic tanks for water-closet system; correct existing failed septic tanks and replaced non-flush systems/micro-flush system in places where water supply is an issue. In a waterlog area to dig a septic tank is an issue therefore Biofil Toilet Digester will be a perfect one in replacement of the conventional septic tank.
Objective of the Product
The technological objectives for the Biofil Toilet Digester System are as follows:
Prevention of sludge build – up
The immediate separation of liquid and solid components of the wastewater through the filters embedded in the biofil digesters prevent sludge build up.
To eliminate odour: airflow is maximized within the digester by
The built-in air gaps within the digester
Maintaining digester depth
To prevent groundwater contamination: the digester is installed above ground; half buried in the ground or below ground for an increased depth of the unsaturated zone attenuation of contaminants is most effective.
Value Proposition
The key benefits of toilet digester are:
Quantifiable economic benefits
The digester is cheaper than the conventional septic tank.
Long-term saving as a result of eliminated need for dislodging.
No operating cost.
Appropriate for any soil condition (clay, rock or high water table area).
Requires very little land
Water can be reused for landscaping.
Environmental health impacts
They eliminate the possibility of costly site remediation and clean-up.
No potential discharge of effluent into water courses;
Sludge is disposed appropriately.
Ecological impact mitigation
The system eliminates water and air contamination.
Digester reduces greenhouse gas emissions as methane is not releases directly into atmosphere.
Waste is treated under aerobic condition.
Biologically filtered of effluent does not trigger prolific plant growth e.g. algal blooms.
The system eliminates ground and surface water contamination.
Human health benefit
Prevention of diseases as there is no direct contact with the excreta.
It promotes good sanitation practice
No odour or sludge accumulation to attract flies that can cause or spread diseases.
The stand alone digester eliminates open defecation.
Reduces the risk of dumping untreated waste into the environment.
Rodent cannot burrow into the digester.
It is fabricated from local materials.
Easy to build and quick to install.
Do not require heavy equipment.
Excavation is optional
It can be easily maintained.
Usability / Maintenance
It meets the need of all users or groups
It provides privacy and comfort for users.
Is simple and promote users’ education on operation and maintenance.
If used appropriately, is of zero maintenance cost.
In-organic waste like pampers, sanitary towels, condom or nylon is prohibited in toilet digester.
Who can use it?
Governments (Federal, State and Local)
Corporate Organizations
Rural and urban development programmes.
Individual Home Owners
Real Estate Developers and Construction Firms.
NGOs, Camp ground.
Schools, Churches and Mosques.
What is in it for you?
More land
More money
More efficiency
Healthy environment

Properly managing our organic waste can dramatically enhance our environment and provide vital by-products for agriculture. Unfortunately the reality now is that most of the organic waste we generate from our homes, offices, workplaces, farms, factories and markets end up in our drains and open spaces and subsequently washed into rivers, streams, lakes and lagoons.
