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.

Does polyacrylamide have mineral coagulants?

General patterns of water treatment with the use of polyacrylamide and its anionic and cationic derivatives have been considered in the absence and presence of mineral coagulants.

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.

How is partially hydrolyzed polyacrylamide wastewater treated?

Yongrui, P., et al. Treatment of partially hydrolyzed polyacrylamide wastewater by combined Fenton oxidation and anaerobic biological processes. Chem. Eng. J. 273, 1–6 (2015).

Does cross-linked polyacrylamide coagulant work better?

Turbidity measurement and the Jar test were used to determine the efficiency of the coagulant. The results showed that cross-linked polyacrylamide worked better than a linear one in coagulating solids particles present in wastewater with improved slurry solids separation efficiency.

Does polyacrylamide remove organic and inorganic substances?

It has successfully removed organic and inorganic substances in the treatment of raw water and wastewater when used alone or with inorganic compounds such as alum [10, 11].The derivatives of Polyacrylamide are Anionic PAM , Cationic PAM , Nonionic PAM.
