How is polyacrylamide used in wastewater treatment?

Polyacrylamide is particularly useful in treating industrial wastewater from sources such as paper mills, food processing plants, and textile factories 16. After addition of 0.05 M solution of polyacrylamide in water, the wastewater is gently stirred or mixed by introducing high frequency air in it. This process encourages the formation of flocks.

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 polyacrylamide be used as a coagulant aid?

The introduction of polyacrylamide (PAM) as a coagulant aid in the context of an Effluent Treatment Plant (ETP) represents a highly efficacious and scientifically substantiated approach aimed at the mitigation of Total Suspended Solids (TSS) within wastewater matrices.

Why do we add polyacrylamide to water during oxidation?

The COD is the imperative factor which is to be determined during the addition of PAM in the water during oxidation. The purpose of the addition of polyacrylamide is to form flocks in the water which ultimately reduces its TSS along with the reduction of COD in the water 14. The Whole experiment was conducted in two conditions.

Can a small-scale textile dyeing industry use effluent waste water?

Conclusion A treatment of effluent waste water for a small-scale textile dyeing industry was taken for study and methodology was proposed with a filter setup using coconut coir, coarse and fine aggregate and activated carbon. The treated effluent was safe to be disposed in nearby water bodies without harming the human beings and aquatic species.

What is cationic polyacrylamide?

Cationic polyacrylamide is a type of synthetic organic polymer that is widely used as a flocculant in wastewater treatment plants 14. It is derived from polymerization of acrylamide and cationic monomers such as diallyldimethylammonium chloride (DADMAC) 10.
