Drinking Water Purification Filter

Filtration systems are used most often in home water treatment to remove sediment or iron, manganese, or sulfur particles. Filtration can also remove some bacteria from water. In mechanical filtration systems, water passes through a medium such as cloth or sand. Particles become trapped on the surface of or within the medium. The pore size, or space between media granules or fibers, determines what size particles a filter can remove.
