Coagulation typically occurs in the early stages of water treatment and involves adding coagulants to raw water. The main function of these substances is to destabilize colloidal particles—tiny, suspended particles that resist settling due to their negative electric charges. By introducing coagulants, which are often positively charged, these destabilized particles begin to clump together in a process known as aggregation.
Water is an essential resource for life, and its cleanliness is paramount for public health, environmental sustainability, and industrial processes. Chemical water treatment methods play a vital role in ensuring that water meets the necessary standards for consumption, irrigation, and various industrial uses. This article delves into some of the key chemical water treatment methods, their applications, and their significance.
