Which treatment method helps to control high turbidity in well water?

The application of coagulants is effective in controlling high turbidity in well water because coagulants work by aggregating suspended particles in water, causing them to clump together. This process is known as coagulation. Once the particles are aggregated, they can be removed more easily through subsequent treatment processes like sedimentation or filtration. High turbidity in water can lead to various issues, including decreased water quality and challenges in disinfection, as particulate matter can shield microorganisms from the effects of disinfectants.

Other treatment methods, while useful in their own contexts, do not specifically address the aggregation of suspended solids in the way that coagulants do. Disinfection with chlorine primarily targets pathogens and may not effectively manage turbidity. Filtration through sand can remove some particulates but usually requires pre-treatment to reduce turbidity levels for effective operation. Reverse osmosis is primarily used for desalination or removing specific contaminants but can be inefficient and costly for high turbidity situations without prior treatment. Therefore, the application of coagulants is the most appropriate and effective method to initially control high turbidity in well water.
