Filling self-developed iron and manganese free filter material or importing high-quality manganese free sand filter material in the iron and manganese removal filter can make the iron and manganese ions directly adsorbed on the filter material without pre-oxidation process.
3.Filter module for removal of iron and manganese
It takes natural manganese sand as the medium whose capacity of manganese is more than 30%~45%. Natural manganese sanduse natural sand as raw material and is made by washing and screening process. It has coarseappearance,looks like a ball,is brown and has MnO2 in it. It is a good catalyst for Fe2+ oxidation to Fe3+. By using the adsorption of manganese sand, it can be removed in the filter tube.
4.Fine filter module
We choose 5 micron PP filter which takes the advantages of small volume, large flow, large amount of pollutant, high accuracy, easy operation, etc. It can remove the impurity, precipitation and suspended matter in water and filter leaked trace impurities. It plays a role of security of the whole water supply system and makes the effluent quality meets the drinking standards.
