How to Remove the Iron and Manganese In Water?

The water contains excessive amounts of iron and manganese, unfavorable to life drinking and industrial production, the water quality situation mostly happened in underground water.

Remove the water of the iron process, is by the aeration, oxidation reaction and filtering, and other three parts, water PH value on ferrous iron oxidation reaction rate effect is very big, aeration oxygenate removes partial CO2, PH value can be increased to 7.0 above, to obtain ferrous iron good oxidation reaction and ferric flocculation precipitation, and then through the filter to remove. But often the water generally contain a small amount of soluble silica, water sample water SiO (OH) 3 - ion strongly adsorbed in the ferric hydroxide colloid list, so that the ferric hydroxide colloid coagulation difficult ah, lead to penetrate filter two influence in addition to iron effect. Therefore, widely used contact oxidation method in addition to iron. This method is a water

After aeration oxygenated, through the filter material clothes in addition to iron and contact oxidation, and in the filter material surface gradually generation has the catalytic activity of iron in the filter film, iron active grinding catalytic effect, thus greatly accelerate the bivalent iron oxidation rate, more effectively remove the water of iron.

Remove the water of the manganese, widely used contact maintenance manganese removal process, make the water containing manganese after aeration, through the filter filtration, high manganese hydroxides and gradually adsorption in the filter material surface, form manganese mass filter membrane, has the contact catalytic effect, thus greatly speed up the oxidation rate, water bivalent manganese was also oxidation for trivalent manganese and adsorbing removal.

But the water of iron, manganese often exist at the same time, and iron oxidation reduction potential than manganese to low, so ferrous iron to high manganese became reductant, therefore, greatly hindered manganous oxidation, so in the water of the coexistence of fe, mn, should first except after iron and manganese. When the water of fe, mn content is higher, it is necessary to adopt two-stage filter processing.
