In baffled reactors usually there are various compartments in an existing primary basin. These compartments initiate and helps in an anaerobic biological degradation of the primary sludge in situ which reduce the amount of sludge activity within the primary tank.
Separation of the solids retention times (SRT) from the hydraulic retention times (HRT) is the key to the successful operation of an ABR. Due to this fact baffled reactor is considered as the best alternative to aerobic treatment and/or primary settlement.
Advantages
Followings are the advantages of the baffled reactors:
- Low strength wastes can be treated in a primary tanks this
reduces the loadings on the secondary treatment plant.
- The production of the sludge will be reduced. This is because lot
of loadings are treated in primary tanks. The reduced loadage in
secondary tanks ensures reduced sludge production.
- The cost of operation is less.
- It can stand very well against robust organic and hydraulic shock loads.
