Biotank Standard

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: 1,500 Litres

Recommended for: Up to 15 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.
