The production of OEM polyacrylamide typically involves the polymerization of acrylamide monomers, which can be achieved through various methods, including solution polymerization, emulsion polymerization, and suspension polymerization. The choice of polymerization technique affects the properties of the final product, including its molecular weight and viscosity. After polymerization, the PAM is often further processed, which may include drying and milling to produce a fine powder or formulating it into a liquid form for specific applications.
One of the most common chemicals used in water treatment is chlorine. Chlorination began in the late 19th century and has since become a staple in public water treatment systems. Chlorine effectively kills a wide range of pathogens, including bacteria, viruses, and protozoa. It is typically added at the water source to disinfect the water before it enters the distribution system. Despite its effectiveness, the use of chlorine can create by-products, such as trihalomethanes (THMs), which have raised health concerns. Consequently, water treatment facilities are constantly seeking alternative disinfection methods or ways to limit chlorination by-products.
