Selector

Mixing for increased sedimentation ability

The purpose of the selector tank is to control and limit the growth of filamentous bacteria, and then to enhance the sedimentation ability of the sludge. Sulzer provides a number of solutions for creating optimal conditions in the selector. In an anoxic or anaerobic selector, submersible mixer types ABS XRW and RW, or the agitator type Scaba, can be used for intensive (flash) mixing of the recirculated sludge and the incoming wastewater. In an aerobic selector, the desired oxygen quantity can be supplied by disc diffuser system types ABS PIK or Sucoflow DS.
