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.

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.

Can polyacrylamide be prepared as linear or cross-linked?

Also polyacrylamide can be prepared either as linear or as cross-linked. In this study both types have been prepared and characterized using FTIR, NMR and viscosity measurement for the molecular weight determination.

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

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.
