What is polyacrylamide (PAM) used for?

In raw water treatment, polyacrylamide (PAM) is used together with activated carbon for the coagulation and clarification of suspended particles in domestic water; in sewage treatment, polyacrylamide (PAM) can be used for sludge dewatering; in industrial water treatment, polyacrylamide (PAM) is primarily used as a formula agent.

Is CPAM a good flocculant for high-concentration activated sludge suspension?

The results show that the addition of CPAM achieves the best flocculation for high-concentration activated sludge suspension, and that the sludge interface descent rate, sludge volume index, and sludge settling ratio are better than those of other flocculants.

How polyacrylamide (PAM) is used in sewage treatment?

In sewage treatment, using polyacrylamide (PAM) can increase the recycling rate of water reuse. In petroleum extraction, polyacrylamide (PAM) is mainly used in drilling mud materials and for enhancing oil recovery, widely applied in drilling, well completion, cementing, fracturing, enhanced recovery, and other oil field extraction operations.

Which flocculant is best for sludge settling?

However, the mixture containing CPAM demonstrated superior performance in V60, sludge volume after 1 h, and SVI compared to the other four flocculants. Therefore, CPAM was determined to be the most effective flocculant for sludge settling. Table 9. Changes in sludge indexes after adding different flocculant dosages of 10 mg/L. 3.2. Orthogonal Test

What are activated sludge systems?

Activated sludge systems have been used to treat a wide range of wastewaters, with over 90% of municipal wastewater treatment plants using them as a core part of the treatment process. The basic function of the wastewater biological treatment process is to convert organic matter into carbon dioxide, water, and bacterial cells.

What is polyacrylamide used for?

Polyacrylamide (PAM) is a collective term for polymers obtained by the homopolymerization or copolymerization of acrylamide monomers under the action of an initiator. It can be used as a coagulant, retention aid, sludge dewatering agent, and flocculant sedimentation agent, among other uses, and has a wide range of applications.
