Question

Flocculation is a process

• A. None of these
• B. that promotes to aggregation of small particles into larger particles to enhance their removal by gravity
• C. that removes algae from stabilization pond effluent
• D. that mixes the coagulant in water

Answer 1

The correct option is B that promotes to aggregation of small particles into larger particles to enhance their removal by gravity

Flocculation is performed after coagulants are added.

It is basically slow mixing or agitation process in which destabilized colloidal particles are brought into intimate contact to promote agglomeration.

Flocculation doesn't mix the coagulant in water.
