Filtration is also used to describe some biological processes, especially in water treatment and sewage treatment in which undesirable constituents are removed by absorption into a biological film grown on or in the filter medium as in slow sand filtration. ( 2. The act or process of filtering; the mechanical separation of a liquid from the undissolved particles floating in it. ( 3. The movement of water and solutes across the cell membrane due to hydrostatic pressure from the cardiovascular system. ( 4.
