Multi-media water purification filter

The filter is filled with quartz sand and activated carbon filter material, which can realize filtration, clarification and adsorption of raw water.

The raw water flows through the quartz sand filter layer, and the suspended solids and impurities in the water are trapped in the filter layer. The intercepted suspended solids are washed out by backwashing, and the filtration retention capacity can be restored. Activated carbon filtration can absorb residual chlorine, odor, and organic matter, colloid and some heavy metal ions in the raw water. 

Sand carbon filters are usually used for pretreatment of RO, UF, NF and other membrane systems, as well as deep clarification after sedimentation tanks and air flotation treatment of produced water, and the turbidity of the produced water is ≤ 5NTU. Fully automatic backwashing and operation are realized through multi-way valves and automatic valves.
