Which treatment method is used to remove sediment from water?

Filtration is the treatment method used to remove sediment from water. This process involves passing water through a medium that captures particles and impurities, allowing clean water to pass through while retaining sediment and other solids. Various types of filters can be employed, including sand filters, cartridge filters, and membrane filters, each designed to target specific sizes and types of particulate matter.

Disinfection, on the other hand, focuses on killing pathogens in water and does not address the removal of sediments. Fluoridation involves adding fluoride to water to help prevent dental cavities, which is unrelated to the removal of solids. Chlorination is a process used to disinfect water by adding chlorine, but like disinfection, it does not specifically target sediment removal. Hence, filtration is the only method among the options provided that effectively addresses sediment removal.
