Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFExplanation:
Coagulation is the destabilization of colloids by the addition of chemicals that neutralize the negative charges by rapid mixing. The chemicals are known as coagulants; usually have higher valence cationic salts (Al3+, Fe3+, etc.). Coagulation is a chemical process.
In coagulation, high turbulence is given by rapid mixing to neutralize the negative charges on suspended solids in water. Therefore, degree of mixing is directly proportional to the degree of turbulence.
Note:
Flocculation is the agglomeration of destabilized particles into large-size particles known as floc by slow mixing which can be effectively removed by sedimentation or flotation.
