Polyacrylamide is a linear polymer compound with functional groups that can adsorb particles.It is like a long rope   that adsorbs particles together to form flocculent polyacrylamide long carbon chains,playing a bridging role between particles.In recent years,it has been widely used as a polymer flocculant in the field of environmental

protection.It can be widely used in various industrial wastewater treatment industries such as paper making,food,  textile,brewing,petrochemical,leather,oilfield  wastewater,etc.Due  to  the  varying  properties  of  the  industrial wastewater mentioned above,the optimal productselection should be determined by laboratory experiments. Usually,the combination of two or even three products has the best effect.
