SBR
The sequencing batch reactor (SBR) is a fill-and draw activated sludge system for wastewater treatment. In this system, wastewater is added to a single “batch” reactor, treated to remove undesirable components, and then discharged. Equalization, aeration, and clarification can all be achieved using a single batch reactor.
Advantages :
- Produce high quality effluent due to a high degree in operational flexibility. Simple modification of the process via PLC.
- Very stable process as compared to hydraulic shock loads and underload.
- User friendly due to automatic operating mode.
- No extra sedimentation tank. Settling is performed in the reactor tank.
- Stable clarification performance.
- Stable bacteria concentration in the reactor a sludge measurement by operator is not needed
- Very low OPEX due to micro-bubble aeration and airlift system (no moving parts in the reactor).
- Low sludge disposal cost, since only the sludge tank and not the complete plant must be emptied periodically.
- Low sludge production
