Sequential Batch Reactor (SBR)
System is operated in a sequential batch reactor mode which eliminates all the inefficiencies of the continuous processes. A batch reactor is a perfect reactor, which ensures 100% treatment. The complete process takes place in a single reactor, within which all biological treatment steps take place sequentially.
The complete biological operation is divided into cycles. Each cycle is of 4 – 6 hrs duration, during which all treatment steps take place.
Explanation of cyclic operation: A basic cycle comprises:
• Fill-Aeration (F/A)
• Settlement (S)
• Decanting-Idle (D/I)
Wastewater treatment system units will be as follows;
– Primary sedimentation & Equalization tank
– SBR tank
– Control panel ( compact with SBR )
– Disinfection Unit ( Chlorine Dosage )
– Sludge drying bed
