Polymer flocculant


In the sewage treatment process, the common sewage treatment flocculant is PAM flocculant. Sewage flocculant is a water-soluble polymer with negative, neutral, and positive charges on its molecular chain, as well as strong adsorption genes. It can adsorb, bridge, and charge neutralize colloids or suspended particles in the water. It destroys the stability of colloids or particles and promotes their flocculation to form larger flocs, thereby improving or accelerating the solid-liquid separation process. Therefore, it is widely used in the treatment of raw water, wastewater, sludge, etc. in various industries.

Polymer flocculant is a water-soluble water treatment agent with large molecular weight. It aggregates the particles by neutralizing the surface charges of the particles suspended in water, and is further adsorbed and cross-linked by countless active groups to form larger and stronger aggregates. Polymer flocculants with this coagulation effect are widely used in the precipitation and suspension treatment of various wastewaters and the concentration and dehydration treatment of various organic sludges.

The Principle of Aggregation

Main Applications

Nonion and anionic polymer flocculant

Effective for sedimentation of suspended substances in various types of wastewater (water, paper, pulp, metal, civil engineering, mining, ceramics, chemicals, food, and other industries), pressure flotation, etc.

Cationic polymer flocculant

Effective for concentrating and dehydrating various types of organic sludge (manure, sewage, paper, pulp, food, and other industries)
