How the bioTank Waste Water Treatment System Works

bioTank septic tank

1. Primary Settlement

Waste water flows into the primary chamber. Initial settlement or separation of solids occur. A sludge layer is formed at the bottom of the tank which should be removed periodically. The liquid effluent passes forward for treatment in the aeration zone.

2. Treatment

From the primary treatment zone the separated liquid now enters the treatment zone where natural bacteria is cultivated using specially designed media, self cleaning diffusers and air supplied by a specialised pump. The micro organisms require oxygen to develop and they then in turn reduce the levels of BOD (Biological Oxygen Demand) and TSS (Total Suspension Solids) in the liquid effluent to reach a 20:30 standard.

3. Final Settlement

The last stage of the treatment is when the liquid enters the final settlement chamber where any small bits of sludge settle to the bottom. This sludge is then returned back to the primary treatment zone. The remaining treated liquid, which is now at its required standard, flows to a percolation area.
