What is a sand filter? What is it for?
Sand filter is based on the use of sand as a filtering material. The filter works with sand grains of selected diameter graded from 0.15 to 0.45 mm. Filters remove particles bigger and smaller than this range. Bigger particles are held by the sifting physical effect and smaller ones by the adhesion effect to the surface of the superficial layers of the filtering element.
