Raw water treatment involves the process of purifying untreated water from natural sources like rivers, lakes, and groundwater, making it suitable for industrial or municipal use. The treatment process typically includes coagulation, sedimentation, filtration, and disinfection. Coagulation removes suspended particles by adding chemicals that clump them together, while sedimentation allows these clumps to settle. Filtration removes remaining impurities, and disinfection, often using chlorine or UV light, eliminates harmful microorganisms. Raw water treatment ensures the removal of contaminants such as bacteria, viruses, chemicals, and debris, ensuring safe and clean water for human consumption, industrial processes, or agricultural use. The efficiency of raw water treatment depends on the water source and the technology employed.
