Before the water enters the clarifier, coagulation and flocculation reagents, such as polyelectrolytes and ferric sulfate, can be added. These reagents cause finely suspended particles to clump together and form larger and denser particles, called flocs, that settle more quickly and stably. This allows the separation of the solids in the clarifier to occur more efficiently and easily, aiding in the conservation of energy. Isolating the particle components first using these processes ma… WebThis wastewater (sewage) treatment instructional video covers the topic of Primary treatment processes and Clarifiers.
