Municipal Treatment

Polyacrylamide is mainly used for solid-liquid separation and sludge dewatering in domestic sewage treatment. It agglomerates suspended particles through adsorption bridging, accelerates floc sedimentation, and significantly improves effluent quality. In the sludge dewatering process, polyacrylamide enhances the flocculation effect of sludge, effectively reduces the moisture content of sludge cake, thereby shrinking sludge volume and lowering disposal costs. It is usually used synergistically with inorganic flocculants as a coagulant aid, and the synergistic effect further optimizes flocculation and sedimentation performance to ensure the effluent turbidity meets standards. In summary, the application of polyacrylamide makes the sewage treatment process more efficient, effectively controls environmental pollution and significantly improves water quality.

The main role of polyacrylamide in drinking water treatment is as a flocculant to remove suspended solids, fine particles and organic matter in water. It flocculates these tiny particles into larger flocs, which are easy to settle and filter, thereby improving the clarity of water quality. Polyacrylamide is often used in combination with inorganic flocculants to enhance the treatment effect and ensure the safety and sanitation standards of drinking water. Its application not only improves the purification efficiency of drinking water, but also reduces the amount of chemical agents, reduces water treatment costs, and ensures the stable operation of the water supply system.

The role of polyacrylamide (PAM) in the treatment of food waste sewage is mainly reflected in the removal of suspended matter, grease separation, wastewater purification and sludge dehydration. Food waste sewage usually contains a large amount of organic matter, grease, suspended matter (SS) and high concentration of chemical oxygen demand (COD), which is difficult to treat. PAM can quickly aggregate fine particles, suspended matter and colloidal substances in wastewater into larger flocs through its strong flocculation properties, promote sedimentation and separation, and significantly reduce the turbidity and pollutant concentration of the water body. In grease separation, PAM can improve the flotation efficiency of oily wastewater and accelerate the oil-water separation process.

Polyacrylamide (PAM) is mainly used as a high-efficiency flocculant in the treatment of landfill leachate to remove suspended solids, organic matter and heavy metal ions. Through charge neutralization and adsorption bridging, it allows the fine particles and pollutants in the leachate to quickly condense into larger flocs, which are easy to precipitate or filter and separate, thereby significantly reducing COD, BOD and heavy metal content. In addition, PAM can also improve sludge dewatering performance, reduce sludge volume, and reduce subsequent treatment costs. Its application effectively improves the efficiency of leachate treatment, reduces environmental pollution, and helps the environmental management of landfills.
