Filter source water about how to remove iron in the production process of aluminum sulfate Tips and methods Filter source water About aluminum in the production of iron How to remove iron and aluminum sulfate method is usually used as a flocculant for purification of drinking water and sewage treatment equipment which , But also for the paper industry. In the preparation, easy doping iron filings affect the concentration of aluminum sulfate, the following describes a method of removing iron in the aluminum sulfate production process: Weigh a certain amount of aluminum sulfate, into the beaker, add distilled water and stir, dissolve with concentrated Sulfuric acid pH. Then add a certain amount of permanganic acid solution, stirring, so that the clear liquid shaking, Fe all shaken, until the mixed, the solution was purple, standing. Controlled at a temperature of about 100 degrees Celsius, heated for a certain period of time, resulting in a brown precipitate, excess permanganic acid was removed with sulfuric acid, allowed to stand after cooling filtration, the resulting filtrate yellowish, and then concentrated crystallization. At present, the widely used method of removing aluminum sulfate recrystallization, precipitation and organic extraction method. Potassium permanganate oxidation method is a new iron removal method, which is simple to operate, easy to control, and low in cost. The aluminum sulphate produced is solid aluminum sulphate and liquid aluminum sulphate. The content of Al2O3 in the solid aluminum sulfate is 15.8-17%, while the content of Al2O3 in the aluminum hydroxide powder is 64-65%. One ton of aluminum hydroxide powder can transport 4 tons of solid aluminum sulfate. The local price of concentrated sulfuric acid is relatively cheap, therefore, with aluminum hydroxide and concentrated sulfuric acid reaction low cost.
