Ensuring the microbiological quality of water is essential, especially in industries like food and beverage, pharmaceutical, and cooling water systems. Disinfectants such as chlorine, ozone, and ultraviolet light are commonly used to eliminate harmful microorganisms. Biocides are used to control biological growth in systems like cooling towers and membrane processes, preventing fouling and contamination.
Chemical suppliers are integral to the water treatment sector. They provide essential chemicals that aid in coagulation, flocculation, disinfection, and pH adjustment. These chemicals include alum, chlorine, sodium hypochlorite, and lime, among others. Each of these chemicals serves a specific purpose
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.
