Sponge iron Filter material

Sponge iron filter material has the advantages of less investment, simple maintenance, low transportation cost and good deoxygenation effect. It can be widely used in anticorrosion of boilers and circulating water equipment. It is a kind of cost-effective energy-saving products Sponge iron filter material deoxygenation principle: the use of a large specific surface area of the sponge iron as the filter material, when the water containing dissolved oxygen through the sponge iron, oxygen in water and sponge iron produced a thorough oxidation reaction of the chemical reaction is as follows

2Fe+2H2O+O2---2Fe(OH)2

    2Fe(OH)2+H2O+2O2---2Fe(OH)3  

After the reaction, the product Fe(OH)3 is a soft flocculent insoluble in water. When it accumulates to a certain extent, it can be discharged by backwashing, and the initial oxygen-removing capacity can be restored.
