Entire human survival depends on water. Most of the world population still don't have access to clean drinking water. The water treatment industry is trying to provide clean water globally and preventing water-related diseases. With the help of water treatment chemicals, they are trying to clean water from the sea, polluted rivers, and wastewater effluents to make them safe for human consumption.
Water treatment methods use four basic processes which include boiler water treatment, cooling water treatment, water purification and treatment of wastewater effluent. All these water treatment processes remove suspended solids, viruses, fungi, bacteria, algae, and minerals. This whole process involves both physical as well as chemical methods. The chemicals used in this process is called as water treatment chemicals.
