Wastewater treatment Usage of polyacrylamide - CHINAFLOC
The introduction of PAM as a chemical flocculating agent to wastewater causes suspended particles in wastewater to aggregate, forming what is known as a floc. In addition, PAM products react with water to form insoluble hydroxides, which upon precipitating, link together to form meshes, physically trapping small particles into a larger floc.

Clarifying agent - Wikipedia
Particles finer than 0.1 μm (10 −7 m) in water remain continuously in motion due to electrostatic charge (often negative) which causes them to repel each other. [citation needed] Once their electrostatic charge is neutralized by the use of a coagulant chemical, the finer particles start to collide and agglomerate (collect together) under the influence of Van der Waals forces.

Get PriceCan flocculants be used in wastewater treatment?
The potential application of conventional flocculants, bio-flocculants and grafted flocculants in wastewater treatment has been verified and well investigated.
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.
Why are polymeric flocculants used in industrial effluent treatment?
Polymeric flocculants, synthetic as well as natural have become very popular in industrial effluent treatment due to their natural inertness to pH changes, high efficiency with low dosage, and easy handling (Singh et al., 2000).
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.
Can direct flocculation replace coagulation-flocculation in wastewater treatment?
As presented above, direct flocculation has been applied to replace coagulation–flocculation in certain types of wastewater treatment. However, its application is mostly limited to organic-based wastewater with high concentration of suspended and colloidal solids; such as food, paper and pulp, and textile effluents.
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.
