Manganese sand filter 
 Mechanical filters, and multi-media filter is used to pre-treatment equipment for water purification equipment, the main role is to remove the suspended material, solid particles, pretreatment of the water. Materials using a variety of materials, such as: PE, steel rubber lined steel spray and steel epoxy anti-corrosion, such as stainless steel. Purpose and role of different filter media, also have the distinction, usually quartz sand, activated carbon, manganese, sand, anthracite. Selection of quartz sand filter also known as quartz sand filter, filter selection anthracite coal called anthracite filter, filter selection manganese sand (except for Fe, Mn) as manganese sand filter, the filter selection of activated carbon activated carbon filter. Can also be used in combination. The main function of the manganese sand filter to remove suspended solids, mechanical impurities, organic matter, reduce the turbidity of the water, adsorption, removal of the pigment in water, chlorine colloidal iron, the aircraft can be selected based on the filtration capacity specifications size, use and operation is very simple.
