Aluminium sulphate ( Aluminium sulfate), its chemical formula is Al2(SO4)3 , it's white rhombic crystal , density 1.69g/mL (25℃) [1]. In the papermaking industry, it is used as the precipitant of the rubber materials such as rosin gum and wax emulsion, flocculant in water treatment, internal retention agent of foam extinguisher, raw material of alum and aluminum white, raw material of petroleum decolorization, deodorant and some medicine, etc.
Aluminium sulphate solid is white crystal granular powder or flake.
The applicable pH value range of industrial aluminum sulfate is related to the hardness of raw water. When treating soft water, the suitable pH value is 5~6.6; when treating hard water, the suitable pH value is 6.6~7.2, and when treating high hard water, the suitable pH value is 7.2~7.8. The applicable water temperature range for aluminum sulfate is 20 C~40 C. Aluminum sulfate is less corrosive, easy to use, and cost-effective.

Packaging specification for sulfate aluminum :25kg/50kg plastic woven bag or kraft paper bag or ton bag, covered with film, also can be packed according to your requirement.
Product storage and transport requirements for aluminum sulfate: keep dry, away from inflammable, corrodible, toxic goods.
Q1.There are specific ways to use aluminium sulphate products.
1, There are two kinds of dosing methods: dry casting and wet casting, and the product is usually prepared into a solution in a certain proportion.
2, The dissolution ratio and dosing concentration should be determined according to the water quality being treated, such as the PH value of the water, the type and content of impurities in the water. When the water quality to be treated is determined, the factors such as dry casting, wet casting, lime regulation and stirring should be tested to select and determine the best use method.
Q2. The sample service requirements.
Normally, we can provide 1kg sample and you need to pay the related express fee.
