Nonionic Polyacrylamide For Sludge Dewatering
Property:
In the paper industry, it can be used as a paper dry strength agent, retention aid, and filter aid, which can greatly improve the quality of paper, save costs, and increase the production capacity of paper mills. It can directly form an electrostatic bridge with inorganic salt ions, fibers and other organic polymers to enhance the physical strength of paper, reduce the loss of fibers or fillers, accelerate water filtration, and play a role in strengthening, retention, and filtration. It can also be used for The white Water Treatment, at the same time, can have obvious flocculation effect in the deinking process.
As a flocculant, non-ionic polyacrylamide is mainly used in industrial solid-liquid separation processes, including sedimentation, clarification, concentration and sludge dewatering. The main applications are: urban Sewage Treatment, paper industry, food processing industry, Wastewater treatment in petrochemical industry, metallurgical industry, mineral processing industry, dyeing industry, sugar industry and various industries. It is used for sludge precipitation and sludge dewatering in the treatment of municipal sewage, meat, poultry, and food processing wastewater, and the negatively charged organic colloids in the sludge are electrically neutralized through the positively charged groups contained in it. The excellent bridging and cohesive function of polymers promotes colloidal particles to gather into large flocs and separate them from their suspensions. The effect is obvious, and the dosage is small.

Polyacrylamide (PAM) is a water-soluble polymer, insoluble in most organic solvents, has good flocculation, can reduce the friction resistance between liquids, and can be divided into non-ionic, anionic, cationic and There are four types of amphoteric type, so anionic polyacrylamide is a water-soluble polymer with negative charge groups.
