What are the different types of polyacrylamide water treatment?

Description: According to ionic characteristics, it can be divided into four types, non–ionic polyacrylamide NPAM, anionic polyacrylamide APAM, cationic polyacrylamide CPAM and amphoteric polyacrylamide. At present, the PAM water treatment is generally anionic type.

What is the use of anionic polyacrylamide in water and wastewater treatment?

The main use of anionic polyacrylamides in water and wastewater treatment is as coagulant aid to bridge the coagulated particles formed when an inorganic coagulants such as alum has been used as the primary coagulant. Fig. 2. Hydrolysis of polyacrylamide

Which Polyacrylamides are used in the thickening process of colliery effluent treatment?

1. INTRODUCTION Polyacrylamides are used in the "thickening" process of colliery effluent treatment. The wastewater contains mainly clay particles, in suspension, which are flocculated using non-ionic and anionic polyacrylamides, which have molar masses in the range of 7-15 million g/mol.

What are the three types of polyacrylamide?

Polyacrylamide can be classified to three categories: non-ionic, anionic and cationic polyacrylamide. Keywords: Polyacrylamide; non-ionic; anionic; cationic; wastewater treatment. 1. INTRODUCTION Polyacrylamides are used in the "thickening" process of colliery effluent treatment.

What is non ionic polyacrylamide used for?

Non-ionic polyacrylamide is commonly used as a coagulant aid to improve the coagulation process and subsequently the floc settling velocity. Higher settling velocity is desired so that the size of the settling tank can be reduced. The result shows

How can polyacrylamide and inorganic flocculants improve water quality?

Improve water quality. In drinking water treatment and industrial wastewater treatment, the combined use of polyacrylamide and inorganic flocculants can significantly improve water quality. Improve the strength and settling speed of flocs.
