When the time between the water that flows through the filter layer from the water portion of the solid suspended material into the upper filter formed by tiny empty eye adsorption and mechanical retention effect is trapped by the surface layer of filter media, while those trapped in suspended solids they overlap and bridging role, as if the filter layer formed on the surface layer of the film, continue to filter the water, suspended matter, which is the so-called membrane filtration filter surface layer. Such filtration not only the surface of the filter layer has a pool water treatment, intermediate when the water enters the filter layer also has this interception, the surface layer is different from the filter, this effect is called the osmotic filtration.
