Water treatment chemicals refer to a diverse group of substances used to improve the quality of water for various purposes. These chemicals encompass a wide range of applications, from disinfection with chlorine or ozone to remove harmful microorganisms, to coagulants and flocculants like alum and polymer additives that aid in the removal of suspended particles in wastewater treatment. pH-adjusting chemicals like lime and sodium hydroxide help balance the acidity or alkalinity of water, while corrosion inhibitors protect pipes and equipment. Additionally, scale inhibitors, activated carbon, and ion exchange resins are used to remove impurities and pollutants. Water treatment chemicals play a vital role in ensuring safe, clean, and potable water for consumption, industrial processes, and environmental protection.
