Aluminum sulfate white orthorhombic crystal powder, density 1.69g/mL (25℃). In the paper industry, it is used as a precipitation agent for rosin gum, wax emulsion and other rubber materials, as a flocculant in water treatment, as a retention agent for foam fire extinguishers, as a raw material for the manufacture of alum and aluminum white, as a decolorizing agent for petroleum, deodorant, some Raw materials for medicines, etc. It can also manufacture artificial gemstones and ammonium alum.

Industrial aluminum sulfate (low iron) is mainly used as a flocculant in factory wastewater treatment. Another use is papermaking, synthetic catalysts, rutile titanium dioxide production.


+

In wastewater treatment, aluminum sulfate is used to polymerize phosphorus and suspended solids, and the resulting flocs are then settled in a settling tank or filtered off in a gravity filter. In drinking water applications, aluminum sulfate acts as a coagulant to remove turbidity and suspended solids by charge neutralization and flocculation in raw water.

Iron Removal Process of Aluminum Sulfate

At present, the production method of aluminum sulfate mainly uses bauxite for production, but because the iron content in bauxite is very high, the iron content in the finished product will be relatively high, and it may be used in this way. It will affect the use effect, so it is necessary to remove the iron in it. Let's take a look at the process of iron removal by precipitation method. Generally speaking, this method is only suitable for ordinary iron removal. First, a certain content of potassium permanganate solution is added to the hot solution. At this time, a large number of brown precipitates will be formed. Then, after filtering, the filtered filtrate is Concentration and crystallization will result in a product with less iron content. The remaining iron is generally high-priced iron, and the product is yellow in color and looks poor in appearance. In the concentration process, a small amount of aluminum flakes can be added to reduce the unclean iron to ferrous iron, so that the obtained product will be light green with good color, and the color of the product will hardly change within 3 months. The pH value of the solution also affects the iron removal effect. The higher the pH of the solution, the better the iron removal. And the higher the pH, the lower the recovery of aluminum sulfate. In this way, after washing the filter residue, the loss of production can be greatly reduced. If the amount of potassium permanganate is insufficient, the removal effect of iron will also be poor, and even the work of iron removal cannot be carried out. Potassium permanganate first oxidizes ferrous ions to Fe, and manganese is reduced to Mn2t. At this time, there is no precipitation of Fe(OH)3: with the continuous addition of potassium permanganate, Mn2+ will be gradually oxidized to Mn'+ . A small amount of aluminum will be adsorbed together to form a precipitate. The higher the content of generated H20, the higher the iron removal rate. The process of iron removal by precipitation introduced above is only one of the methods for removing iron from aluminum sulfate. We need to choose according to actual needs when using various methods.
