How Our System Work
SBR Standard refers to sequential batch reactor. This technology is a controlled wastewater treatment process where batches of wastewater undergo treatment in a sequence. This control process is as illustrated below:
Loading phase
The sewage water collected in the collection and equalization chamber is fed into the SBR tank. The filling of water in the SBR tank is done through an airlift pump or mechanical pump depending on the design.
Aeration phase
Activated sludge in the presence of air/ oxygen consumes the pollutants in the SBR chamber. Air is supplied in a timesequenced manner in this phase
Rest phase
During the rest phase, the activated sludge settles at the bottom of the tank. A clear water zone appears on the upper layer of water in the SBR tank.
Clearwater extraction
The clear water from the upper layer is then transferred for subsequent reuse or disposal to the treated water tank, drain or farm. Thereafter, the settled activated sludge in the SBR tank is returned to the collection tank and the process is repeated. A complete purification cycle takes approximately 7 hours
