Biotank Compact

The Biotank Biodigester® is a modern biological alternative to conventional septic tanks — factory-made and eco-friendly. Designed to biologically digest human waste using naturally occurring anaerobic bacteria, providing a cleaner, low-maintenance, and long-term sanitation solution for homes, rentals, and commercial properties.

Capacity: 1,000 Litres

Recommended for: Up to 10 continuous users

How It Works
Wastewater moves through three treatment chambers:

1. Inlet Chamber
Raw sewage enters the biodigester. Heavy solids settle while lighter materials float.

2. Digestion Chamber
Anaerobic bacteria digest organic waste, breaking down solids into simpler compounds and significantly reducing sludge accumulation.

3. Sedimentation & Clarification Chamber
Further treatment occurs. Treated effluent is separated and displaced to a soak pit as new wastewater enters — creating a continuous, self-regulating treatment cycle that requires far less maintenance than conventional septic systems.
