Sequencing Batch Reactor.

The Sequencing Batch Reactor, SBR, is a fill-and-decant, non-steady state activated sludge waste-water treatment process in which each reactor is filled during a discrete time period, and then operated in a batch treatment mode. The SBR accomplishes equalization, aeration and clarification in a timed sequence, in a single reactor basin. A single cycle for each reactor consists of five discrete periods, Fill, React, Settle, Decant and Idle.

Anoxic, anaerobic or aerobic conditions are generated as required to allow Organism Selection to take place. The proliferation of specific desirable micro-organisms is encouraged, while the growth of undesirable micro-organisms is inhibited. Micro-organisms can be selected and acclimated to a wide range of food processing, industrial and chemical processing wastes. The non steady state operation produces an inherent robustness.

The systems are unique in their ability to handle influent flows ranging from one fifth to over three times design flow and a wide range of organic loads and industrial pollutants while maintaining the required quality of reusable water. In addition to BOD removal, effective nitrification, denitrification and biological phosphorous are achieved.
