Membrane Bio Reactor (MBR)

SBR is a sequential batch reactor process. It provides highest treatment efficiency possible in a single step biological process. SBR - System is operated in a batch reactor mode which eliminates all the inefficiencies of the continuous processes. A batch reactor is a perfect reactor, which ensures 100% treatment.Two modules are provided to ensure continuous treatment and into some case one module. The complete process takes place in a single reactor, within which all biological treatment steps take placese quentially.

NO additional settling unit / secondary clarifier is required!

The complete biological operation is divided into cycles. Each cycle is of 3 - 5hrs. duration, duringwhich alltreatmentstepstakeplace.Into SBRB as in 70% down side hydraulic volume for sludge and 30% upside hydraulic volume for biological process ofwater.

Explanation of cyclic operation:

A basic cycle comprises:

• 1. Fill-Aeration (F/A)
• 2. Settlement (S)
• 3. Decanting (D)

A Typical Cycle

During the periodofa cycle , the liquid is filled in the SBRB as inuptoaset operating water level.Aeration Blowers are started for aeration of the effluent. After the aeration cycle, the biomass settles under perfect settling conditions. Once Settled the supernatant is removed from the top using a DECANTER. Solids are wasted from the tanks during the decanting phase. These phases in a sequence constitute a cycle, which is then repeated.
