Industrial production of non-iron aluminum sulfate, aluminum sulfate, iron-free manufacturers Which is good, to get the iron sulfate leach bauxite (Fe2 + and Fe3 +) of aluminum sulfate solution, heated to a certain temperature, stirring, adding a certain amount of potassium permanganate solution no iron and manganese sulfate solution of aluminum sulfate, to generate activated manganese dioxide in solution without iron aluminum sulfate manufacturers Jinan, adjusting the pH of the solution, the reaction period of time, Fe (OH) 3 and manganese dioxide adsorption occurs coprecipitation effect, finally obtained no iron aluminum sulfate products. Uses one, mainly for drinking water, industrial water, oil field injection water, cooling water and a variety of water (such as urban sewage, oily wastewater, sewage and dyeing, papermaking wastewater, sewage bleaching mills, etc.) treatment. 2, paper sizing precipitating agent, sugar decolorization clarifying agent. 3, for a number of areas tanning, pharmaceuticals, cosmetics, and precision casting.
