Nowadays, the demand for potable water is constantly increasing, due to meeting human needs and supporting industrial activities. With increasing urbanization and economic development, the current water supply is unlikely to meet the ever-increasing demands. Hence, the chemical industry uses innovative water treatment methods in order to make the water acceptable for end-use.

Such as drinking, cooking, irrigation, and industrial purpose to name a few. Water treatment methods use four basic processes, which include boiler water treatment, cooling water treatment, water purification, and sewage treatment. The substances that are removed during the water treatment process are suspended solids, viruses, fungi, bacteria, algae, and minerals. The process includes physical and chemical methods. The chemical used in this process is called a water treatment chemical.
