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).

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 effective is turbidity removal of polyacrylamide coagulants?

However, applying 200 mg L-1 of the polyacrylamide at a contact time of 35 min resulted in 89% turbidity removal. Evaluating the efficiency of turbidity removal of both coagulants, no significant differences were noted in the ability of both coagulants to clarify wastewater.

Does polyaluminum chloride remove turbidity?

The study compares the efficacy of polyaluminum chloride and polyacrylamide in removing turbidity, representing the number of suspended solids, under varying pH, mixing time, temperature, oil, and suspended solids conditions. Optimizing these parameters is crucial for enhancing the coagulation treatment’s efficiency.

Which polymer is used to remove pollutants from a wastewater?

The composted polymer then was used for the removal of pollutants from a wastewater. RSM was used to analyze the effect of the composite polymer dose with the initial pH and enhance the flocculation process. Polyacrylamide (PAM) provided by HIMEDIA laboratories Pvt. Ltd. (Ind ia). Aluminium Chloride (AlCl) by Scharlab S.L. (Spain).

Does polyacrylamide add to soil?
