2. 3 rd Anaerobic tank 4 th Anaerobic tank 5 th Anaerobic tank THEAN CHOR FARMING 6 th tank This mechanism prevent sludge from flowing into the 6 th tank.

3. THEAN CHOR FARMING 6 th tank Wastewater in the 6 th tank is pump into the aerobic tank through this pipe. The 6 th tank is used more as a transit tank, the wastewater will be pumped back to separation tank if there is too much sludge in it. When the wastewater reaches this tank, the BOD has reduced to about 300 mg/L.
