What factors affect the flocculation effect of cationic polyacrylamide (CPAM)?

Cationic polyacrylamide (CPAM) is a commonly used flocculant for water treatment. Factors that affect the flocculation effect and can be controlled manually include the type and dosage of CPAM, wastewater pH, stirring time and settling time, and their reasonable setting is critical to the flocculation effect of CPAM.

Does nonionic polyacrylamide affect the flocculation process of removing clay?

The presence of nonionic polyacrylamide has slight effect on the flocculation process efficiency of removing clay from industrial wastewater. On the other hand, usin g o f prepared flocculent, it was found that the presence of soap in water in large concentrations has a negative effect on flocculation process.

What is polyacrylamide used for?

Polyacrylamide and its co-polymers are used as flocculants or coagulants in industrial wastewater treatment .Homo-polymer is used in this application and can be either nonionic, cationic or anionic depending on the types of wastewater needs to be treated. Also polyacrylamide can be prepared either as linear or as cross-linked.
