High quality filter material based on magnetite ore for water purification

Specifications Magnetite apply to large resistance in the tube for water distribution system

1)quality assurance

2)18 year's history

1.Magnetite filter is applied to a large resistance to water distribution pipe system.usually associated with Anthracite coal filter material and quartz sand,   2.and is a integrant filter material in three-layer filter chamber which is characterized by the high strength,fast filtering velocity and few mixedLayer when back washing.   3.In addition,it is effencient to  deferrization, demanganization, defluorination.   common size: 0.25~0.5mm 0.5~1.0mm 1.0~2.0mm 2.0~4.0mm 4.0~8.0mm 8.0~16.0mm 16.0~32.0mm   Physical and chemical analysis
