The Sequencing Batch Reactor (SBR) is the variation of the activated sludge treatment system that performs treatment operations in a single tank. It is well proven and widely accepted as a reliable process for carbonaceous and nutrient removal. SBR process is favored by many professionals because they do not require separate clarifiers. The SBR operates on a fill and draw basis and originally in a batch basis. However the variation features in our process allows flow to enter one of the tanks at all times relying on the cycle control of the multiple bioreactors.
