Polyacrylamide is the most frequently used water purifier in the sewage treatment industry. There are many types of polyacrylamide, which accounts for the share of sewage in different industries. So what types of polyacrylamide are there?How is it classified?

Polyacrylamide classification

Cationic polyacrylamide: According to the ionization index, it can be divided into 10-60 models. It is mainly used in steel mill wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater, and de-sludge wastewater industries. It has the effects of purification, sedimentation, filtration, and viscosity.

Anionic polyacrylamide: According to the molecular weight index, it can be divided into 5-25 million models. It is mainly suitable for wastewater treatment such as suspended particle thickness, high concentration, positive ion charge, and water pH value of neutral or alkaline steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater, etc.；

Nonionic polyacrylamide: according to the molecular weight, it is divided into 3-25 million, which is mainly used as a coagulant.；

Zwitterionic polyacrylamide: According to the molecular weight of 3-25 million, it is mainly used as a thickener.

Summary: Basically, except for cations, polyacrylamides can be classified according to molecular weight. Different types of polyacrylamides are used according to different water quality. Among them, nonionic and zwitterionic will have different names in different regions and manufacturers, but the effects are the same.
