Chi Chun Tangshan Water Works Co., Ltd. In addition to the development of iron and manganese filter water treatment equipment, using advanced process design processing technology, can effectively remove iron and manganese in the water, so as to achieve bleaching to taste water to pass security compliance requirements, when ferromanganese containing groundwater flows from the filtration equipment except when ferromanganese, pre-pretreatment aeration device with added oxidants, have made of iron in water (manganese) ions begins to oxidize, at which time flows manganese sand filter layer, It will further contact oxidation reaction occurs, so the role of water in biological and physical entrapment filter surface adsorption of multi-level filtration, the water stepwise precipitation of iron and manganese ions so as to be completely absorbed by the removal of the principle of JCSW-CTM series of water treatment equipment is mainly composed of iron and manganese in addition to the aeration device, biofilter backwash pump and other components. This device uses a new filter medium JCSW series dedicated inter ferromanganese media, both manganese sand, quartz sand, activated carbon multiple effects, with good filtration and flocculation sedimentation, treated effluent reached drinking water health standards JCSW special iron 1. Initial manganese filter characteristics that can run in addition to iron, manganese sand compared to its maturity has shortened 2. In addition to the taste function 3 color light weight, easy to backwash and backwash long period, effective 4. Operation and backwash pump can be equipped with the same type, each other back underground drinking water is suitable for a wide range of iron and manganese in addition to urban, rural centralized water supply for industrial use
