Application of Polyacrylamide in Domestic Sewage

 Application of Polyacrylamide in Domestic  Sewage

        The main use of polyacrylamide in domestic sewage is to remove suspended particles through its flocculation effect, achieving clarification and separation of sewage. Polyacrylamide promotes the rapid aggregation and precipitation of suspended particles through electrical neutralization and its inherent adsorption bridging effect, thereby separating and clarifying wastewater.

Specific application methods of polyacrylamide in domestic sewage treatment

Flocculation and sedimentation: In domestic sewage treatment, polyacrylamide can promote the rapid aggregation and precipitation of suspended particles through electrical neutralization and its inherent adsorption bridging effect, achieving separation and clarification.

Sludge dewatering: Polyacrylamide also plays an important role in the sludge dewatering process by increasing the viscosity of the sludge, making it easier to dewater.

The effect and advantages of polyacrylamide in domestic sewage treatment

Improving treatment efficiency: Using polyacrylamide can significantly enhance water treatment efficiency and improve effluent quality.

Reduce sludge production: Under the same treatment conditions, the use of polyacrylamide can greatly reduce the amount of flocculant and decrease sludge production.

Shortening processing time: Polyacrylamide has a high molecular weight and strong bridging and wrapping effects, which can form larger flocs. The settling speed of flocs is faster, shortening the settling time and making it more conducive to sludge dewatering.

Chemical properties and applicable conditions of polyacrylamide

Polyacrylamide is a water-soluble polymer with the chemical formula (C3H5NO) n. It has good thermal stability and solubility, and can form a uniform and transparent liquid in water. After long-term storage, the viscosity of the solution may decrease due to degradation.

           In summary, polyacrylamide has significantly improved the treatment efficiency, shortened the treatment time, and reduced the generation of sludge in domestic sewage treatment through flocculation and sludge dewatering. It is an efficient and economical auxiliary agent for sewage treatment.
