BIO-DIGESTION PROCESS

How The Bio Septic Tank Works

A natural, highly efficient multi-stage anaerobic bacterial breakdown process that turns waste into clear, reusable water and harmless trace gas.

01
Waste Water from Toilet

Raw blackwater and greywater safely enter the inlet chamber without backflow.

02
Biological Treatment with Special Culture

Specialized anaerobic bacteria culture inoculates waste, active for 6 to 12 months.

03
Sludge Converts to Water & Gas

Organic solids decompose swiftly into harmless treated water and inert trace biogas.

04
Treated Water (Soak Pit / Reuse)

Clear, odourless treated water discharges safely into soak pits or subsoil garden recharge.
