Municipal Treatment

Polyacrylamide is mainly used for solid-liquid separation and sludge dewatering in domestic sewage treatment. It flocculates suspended particles to make them settle quickly and improve water quality. In the sludge dewatering process, polyacrylamide enhances the flocculation effect of sludge, reduces the sludge volume and reduces the treatment cost. It is usually used in conjunction with inorganic flocculants to further improve the treatment effect and ensure clear effluent. Through the application of polyacrylamide, domestic sewage treatment is more efficient, environmental pollution is effectively controlled, and water quality is significantly improved.

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.
