Treatment of composite mana by iron pollution

If the composite covers have been contaminated with iron, we should use a ratio of 5: 100 or 10: 100 hydrochloric acid for soaking. After the composite material fails, drain with the exchanger. Mixed composite material failure, the normal regeneration to the yin and yang composite material separately, were transferred to the anion, cationic regenerator. 5% to 10% hydrochloric acid is added to each exchanger or regenerator, and the surface of hydrochloric acid is about 20-30 cm above the surface of the composite material. Soak for 5-10min, from the bottom of each exchanger or regenerator into the compressed air to scrub, and then continue to soak, 30min, after scrubbing, soaking. The above process is repeated several times until the acidity of the soaking solution and the iron content is substantially constant.

The composite gauze material is normally regenerated with sulfuric acid at a specific concentration, until the acid concentration of the cation exchange or regenerator is equal. The anti-baking layer is first applied to the negative bilayer bed, Strong alkali-yin composite material, separated with purified water for 30min, and then with a certain concentration of sodium hydroxide lye for normal regeneration, into the alkali until the bilayer bed inlet and outlet concentrations are equal; Rinse about 30min or so, and then with a certain concentration of sodium hydroxide lye for normal regeneration, into the alkali until the anion regeneration of the import and export of alkali concentration equal.
