The coagulation principle of the water treatment process of the sewage treatment plant mainly involves the aggregation process of colloids and tiny suspended solids in the water. By adding chemicals to the water, the colloid particles that are difficult to precipitate in the water are destabilized a
READ MORECommon water quality standards can be roughly divided into three categories: physical, chemical and biological indicators. For example, indicators such as color, temperature, and turbidity are physical indicators, PH, COD, ammonia nitrogen, total nitrogen, total phosphorus, etc. are chemical indicat
READ MOREAnionic polyacrylamide (APAM) is a water-soluble, high molecular weight polymer that has become indispensable in modern wastewater treatment. Chemically, it is a synthetic polymer formed by polymerizing acrylamide monomers with anionic functional groups. These negatively charged groups give APAM its exceptional ability to interact with a wide range of suspended particles in water.
