Why is polyacrylamide used in water treatment?

With the increasing global water scarcity and escalating environmental pollution, efficient water treatment has become paramount. Polyacrylamide, as a versatile polymer compound, has demonstrated significant achievements in the field of water treatment. PAM is widely used as a coagulant and flocculant in wastewater treatment.

What is the demand for polyacrylamide in water treatment applications?

Polyacrylamide demand in water treatment applications dominated the market with a revenue share of more than 38.0% in 2022. The rising demand for polyacrylamide to treat municipal sewage, industrial wastewater, and drinking water purification plants is expected to propel demand.

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.

What are water treatment polymers?

Water treatment polymers are substances used in water treatment processes. They cause flocculation – the adhesion of fine solid particles to a 'backbone' polymer molecule. There are anionic and cationic polymers, and also non-ionic polymers.

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.

How was polyacrylamide synthesized?

Polyacrylamide was synthesized using free radical polymerization with high molecular weight with M = 1.669 x 106 g/mol. The presence of nonionic polyacrylamide
