Chemical mixing sewage

Mixing chemicals into activated sludge

Chemicals must sometimes be mixed into the activated sludge before it enters the secondary sedimentation tank. Whenever this done, it is important to achieve an even distribution of the chemicals. Chemicals may be added to perform the chemical removal of phosphorous on effluent from the biological process. In other circumstances, chemicals such as cationic polyelectrolytes with a high molecular weight may be added to improve the quality and settling ability of flocs formed in the activated sludge process.

In both of the cases above, the Sulzer agitator type Scaba can ensure that chemicals are uniformly distributed throughout the wastewater volume.
