• Improve the sedimentation performance of suspended activated sludge; the physical screening device will discharge the sludge with poor sedimentation performance from the system;

• Adapt to operating conditions (aerobic-anoxic-anaerobic); increase the processing capacity by 30-50%;

• Control the expansion of filamentous sludge in the biochemical tank of the existing sewage treatment plant; it can be applied to the upgrading of the existing sewage treatment plant;

• It can also be applied to new sewage treatment plants to reduce the volume of structures;
