Anionic PAM(polyacrylamide), copolymerized by acrylamide and acrylate monomer, is a super high molecular weight anonic poymer, that is 12 million minum. It has great adsorption-bridge effect. Different model can be used according to the different application and the requirement of clients for the products performance. Anionic PAM (flocculant)is mainly used: 

1 Industrial wastewater treatment 
2 Drinking water treatment 
3 Starch ethanol plants and the loss of plant starch lees recovery 
4 Oil displacement agent for the tertiary oil recovery 
5 Water shutoff agent 
6 Auxiliary of papermaking industry 

Anionic PAM(polyacrylamide) is a kind of flocculant and it has been widely used in all kinds of waste water treatment process, for more information, pls contact me.
