What are the steps in water treatment used by community water system?
They typically consist of several steps in the treatment process. These include: (1) Collection; (2) Screening and Straining; (3) Chemical Addition; (4) Coagulation and Flocculation; (5) Sedimentation and Clarification; (6) Filtration; (7) Disinfection; (8) Storage; (9) and finally Distribution.
How is river water treated?
The water-treatment process involves four steps, in this order: coagulation, sedimentation, filtration, and disinfection. The purpose of coagulation is to create dirt clumps that are heavy enough to sink, which is important for the next step in the process.
