Another crucial aspect of chemical treatment is the removal of heavy metals and other harmful substances. Various chemical agents, such as lime, sodium sulfide, or chelating agents can be introduced to precipitate heavy metals, allowing them to be efficiently removed. This is particularly important in industrial areas where water may be contaminated by metals like lead, mercury, or cadmium. Ion exchange is another method that can be quite effective for softening hard water by replacing calcium and magnesium ions with sodium ions.
Water treatment is an essential process that ensures safe drinking water and protects public health. The treatment of water involves various stages, each employing specific chemicals to remove impurities, disinfect the water, and make it suitable for consumption. The use of chemicals in this process is crucial for managing water quality and preventing waterborne diseases. This article explores the primary chemicals used in water treatment, their functions, and their significance.
