Which process is used to remove suspended solids from water?

Filtration is the process used to remove suspended solids from water. This method involves passing water through a porous medium that can trap particles, allowing clear water to flow through while retaining the solids. The effectiveness of filtration can vary depending on the size of the filter medium and the nature of the suspended solids, but it is a widely employed technique in water treatment facilities to improve water clarity and quality.

While coagulation involves adding chemicals to help particles clump together into larger aggregates that can then be filtered out, it is not the process itself that removes the solids directly. Reverse osmosis primarily removes dissolved solids rather than suspended solids by forcing water through a semi-permeable membrane. Adsorption also does not primarily target suspended solids; instead, it involves the attachment of dissolved particles to a solid surface. Thus, among the processes listed, filtration is specifically designed for removing suspended materials effectively.
