Through two-phase aqueous polymerization, amphoteric polyacrylamide (AmPAM) emulsion, as an environmental friendly flocculant for the tannery wastewater, was firstly synthesized using ammonium sulfate aqueous solution as the dispersion, using acrylamide, cationic monomer ethylene methyl propenoyl-trimethylammonium chloride (DMC), and anionic monomer acrylic acid (AA). The structure and ...
Get PriceWhy is anionic polyacrylamide used in wastewater treatment?
Due to its negatively charged characteristics, anionic polyacrylamide can effectively combine with positively charged particles in water, forming larger flocs and promoting sedimentation of particles. Anionic polyacrylamide is suitable for treating positively charged particles such as suspended solids and colloids in wastewater.
What is anionic polyacrylamide used for?
Anionic polyacrylamide is suitable for treating positively charged particles such as suspended solids and colloids in wastewater. Compared to cationic PAM, anionic polyacrylamide is usually less expensive and is suitable for large-scale use.
How to synthesize amphoteric polyacrylamide flocculants?
Copolymerization of AM with various functional monomers or betaine-based monomers is also a general way to synthesize amphoteric polyacrylamide flocculants. Zhu et al. used amphoteric polyacrylamide (AmPAM) obtained by the copolymerization of AM, AA and methyl acrylic acid ethyl trimethyl chloride ammonium for treating tannery wastewater .
Which is better cationic or anionic polyacrylamide?
Cationic PAM is especially suitable for treating negatively charged organic substances such as high-concentration colloids and suspended solids in wastewater treatment. Due to its complex production process and superior performance, cationic PAM is usually priced higher than anionic polyacrylamide.
What are the different types of polyacrylamide adsorption?
In practice, however, this adsorption is often enhanced by using modified (anionic or cationic) forms 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
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.
