Biofil Digester 


How it Works

The Biofil Digester technology mimics the decomposition found under forests’ floors and other natural environments. Living organisms (both microorganisms and macro-organisms such as earthworms) in an enclosed environment treats all organic degradable matter through the natural process of aerobic decomposition. Wastewater and fecal matter enter at the top of the Biofil Digester where rapid separation of solids and liquid contents of the waste occurs. The digester is essentially a biological filter consisting of a medium of soil and pervious concrete. Bacteria, other organisms degrade solid fecal matter. All liquids are organically filtered out of the bottom of the digester and drained into the soil where further and final decomposition occurs. Other solids (toilet paper & all degradable anal cleaning material) are decomposed and converted into rich & safe soil. When the Biofil Digester is used in the flush toilet situation, high nutrient biologically treated water is made available for effective landscaping and beautification of the environment. The design is simple, replicable, and affordable


  • Requires very little land space (6×2/4×2)

  • Water can be reused for landscape

  • They eliminate the possibility of costly site remediation and clean-up.

  • No potential discharge of effluent into water courses.

  • 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.

  • The system eliminates ground and surface water contamination.

  • Prevention of diseases as there is no direct contact with the excreta.

  • It promotes good sanitation practice

Biofil Digester 

  • Rapid separation of solids and liquids

  • Aerobic composting of solids and  

  • Bio-filtration of wastewater

Because the digester and effluent pipes are always installed above the ground water table, water contamination is completely eliminated. Waste is treated under complete aerobic conditions eliminating odour and air pollution. The system eliminate the possibility of costly site remediation and clean-up (as in the case of failed septic / KVIPs)
