(Note: MnO2 ≥ 35% can remove both iron and manganese, and MnO2 ≤ 30% can only be used for iron removal in groundwater) manganese sand filter material is mainly used to reduce the total content of iron, manganese and manganese in water. According to the hygienic standard of domestic and drinking water in China, its iron content is ≤ 0.3 ‡ / L and manganese content is ≤ 0.1 ‡ / L. drinking water with too high iron and manganese content for a long time will seriously affect your health Typical use: Iron removal by natural manganese sand is a contact catalytic iron removal process, which is suitable for iron removal when the iron content in groundwater is less than 20mg / L. The high valence manganese contained in natural manganese sand can oxidize the divalent iron in water into trivalent iron, and form a catalytic "active filter membrane" on the surface, which further improves the iron removal effect. After aeration, all iron removal processes can be completed only by one filtration of natural manganese sand. It is commonly used in iron removal and manganese removal filtration devices for drinking water, and the water filtering effect is very good.

Product application: Columnar activated carbon is also widely used in toxic gas purification, waste gas treatment, industrial and domestic water purification, solvent recovery and so on. Columnar activated carbon is used in all aspects of industrial and agricultural production, such as alkali free deodorization (refined mercaptan), ethylene desalted water (refined filler), catalyst carrier (palladium, platinum, rhodium, etc.), water purification and sewage treatment in petrochemical industry; Water quality treatment and protection of power plants in the power industry; Chemical catalysts and carriers, gas purification, solvent recovery and decolorization and refining of oils and fats in the chemical industry; Refining and decolorization of beverages, alcohol, monosodium glutamate mother liquor and food in the food industry; Gold extraction and tail liquid recovery in the gold industry; Sewage treatment, waste gas and harmful gas treatment and gas purification in environmental protection industry; As well as the cigarette filter tip, wood floor moisture-proof, odor absorption, automobile gasoline evaporation pollution control, and the preparation of various impregnant solutions in related industries. Activated carbon will have excellent development prospects and broad sales market in the future. Columnar activated carbon has a good adsorption effect on volatile organic compounds in water, and the removal rate of various volatile organic compounds in water can reach 25% ~ 65%. Comparing the adsorption laws of various organic compounds with different molecular weights, it can be seen that for volatile organic compounds, the greater the molecular weight, the higher their removal rate. This is similar to the adsorption law of phenol and cationic light yellow, that is, for small molecular organics in water, the greater the molecular weight, the easier it is to be adsorbed by activated carbon. Activated carbon has a good removal effect on extractable organic matter with molecular weight less than 480, while the removal efficiency of macromolecular organic matter is very low. This is mainly due to the steric effect of the microporous structure of activated carbon. Too large organic molecules cannot enter the pores of activated carbon and can only be adsorbed on the surface of activated carbon. characteristic: The advanced nature of columnar activated carbon: Due to the use of high-quality sawdust and coconut shell as raw materials, the columnar activated carbon has lower ash content, less impurities, gas phase adsorption value and CTC than the traditional coal columnar carbon. Coal columnar activated carbon has the advantages of developed void structure, large specific area, strong adsorption capacity, high mechanical strength, low bed resistance, good chemical stability, easy regeneration and durability. The pore size distribution of the product is reasonable to achieve the maximum adsorption and desorption, so as to greatly improve the service life of the product (average 2-3 years), which is 1.4 times that of ordinary coal carbon. Applicability of columnar activated carbon: ① Gas phase adsorption; ② Recovery of organic solvents (recovery of benzene gas toluene and acetone in acetate fiber industry); ③ , impurities and harmful gases are removed, and waste gas is recovered; ④ Recovery of excess gasoline in refineries, gas stations and oil depots; ⑤. It is used for preparing trichloroethylene by catalytic dehydrogenation of perchloroethane with activated carbon. |
