Principle of action

The main mechanism of cationic coagulants in sludge treatment includes electric neutralization, adsorption and bridging, and flocculation and settlement:

Electricity neutralization: sludge particles usually have negative charge, cationic coagulant with cationic groups, can neutralize the negative charge on the surface of sludge particles, reduce the electrostatic repulsion between particles.

Adsorption and bridging effect: cationic coagulant connects multiple sludge particles together through its long chain structure, forming larger flocs and enhancing cohesion between sludge particles.

Flocculation and settling: after electric neutralization and adsorption and bridging effect, the large flocs formed will settle rapidly under the effect of gravity, which is convenient for sludge thickening and dewatering.

Product Advantages

Efficient flocculation: Cationic coagulant can improve the flocculation efficiency of sludge and accelerate the settling and dewatering process of sludge particles.

Wide applicability: cationic coagulant has good treatment effect on various types of sludge (such as municipal sludge, industrial sludge, paper sludge, etc.).

Reduction of treatment cost: The use of cationic coagulant can reduce the volume of sludge, reduce the cost of sludge treatment, transportation and disposal.

Improvement of sludge characteristics: cationic coagulants can improve the dewatering performance of sludge, reduce the water content of sludge, increase the solid content of sludge and improve the physical characteristics of sludge.

Environmental friendliness: Most of the modern cationic coagulants have good biodegradability and are friendly to the environment.
