Water treatment chemicals are the chemical compounds used in the treatment of water to remove impurities, which cause scales, corrosion, high turbidity, and biological imbalance. Water treatment chemicals are majorly used in the municipal, commercial, and industrial end-use for water treatment. The type and degree of water treatment strongly depend on the source of the water and its intended use. Water for domestic use must be thoroughly disinfected to remove microorganisms before supply to households. On the other hand, industrial water may contain microorganisms, but must be treated to a certain extent to turn the water soft and to prevent scale formation and corrosion. The global water treatment chemicals market size is projected to grow from USD 35.9 billion in 2022 to USD 42.2 billion by 2027, at a CAGR of 3.2% between 2022 and 2027.

Raw water treatment is used to remove a number of impurities, including suspended solids, silica, and bacteria, from the water obtained from various sources, such as a lake, river, well, and secondary or tertiary treatment reuse. This segment is the largest in the water treatment chemicals, based on application. Growing scarcity of freshwater will futher drive the growth of this segment. Water treatment chemicals are used in various end-use industries such as municipal, oil & gas, power, food & beverage, chemicals & fertilizers, metals & mining, and pulp & paper.
