1.Principle of operation

在除铁锰过滤器中装填自主研发免氧化除铁锰滤料或者进口优质免氧化锰砂滤料，即可使高铁锰水无需经过预氧化过程，使铁锰离子直接吸附于滤料上。

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 sand use natural sand as raw material and is made by washing and screening process. It has coarse appearance,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.
