The water treatment industry is playing an important role in providing clean water globally and prevents various water-related diseases. With the innovative boiler water treatment chemicals and other related chemicals, water from the sea, polluted rivers and wastewater effluents can now be made safe for human consumption. the chemical industry uses the innovative ways of water treatment in order to make water acceptable for end-use, such as drinking, cooking, irrigation and industrial purpose to name a few. The water treatment methods use four basic processes that include boiler water treatment, cooling water treatment, water purification and treatment of wastewater effluent. The substances that are removed during the water treatment process are suspended solids, viruses, fungi, bacteria, algae and minerals. The process involves both physical and chemical methods. The chemical used in this process are called water treatment chemicals.
