44 TECHNOLOGY BRIEF OF TREATMENT PROPOSED: The Sequencing batch reactor (SBR) process is a sequential suspended growth (activated sludge) process in which all major steps occur in the same tank in sequential order (figure 1). There are two major classifications of SBRs: the intermittent flow (IF) or true batch reactor, which employees all the steps in figure 1, and the continuous flow (CF) system, which does not follow these steps. Both have been used successfully worldwide installations. SBRs can be designed and operated to enhance removal of nitrogen, phosphorus, and ammonia, in addition to removing TSS and BOD. The intermittent flow SBR accepts influent only at specified intervals and, in general, follows the five-step sequence. There are usually two IF units in parallel. Because this system is closed to influent flow during the treatment cycle, two units may be operated in parallel, with one unit open for intake while the other runs through the remainder of the cycles. In the continuous inflow SBR, influent flows continuously during all phases of the treatment cycle. To reduce short circuiting, a partition is normally added to the tank to separate the turbulent aeration zone from the quiescent area. 72 PROJECT REPORT
