Calcium Aluminates for Water Treatment -1
Calcium Aluminates powder, its main mineralogical composition is CaO.AL2O3 and CO2.AL2O3 which have stronger activity, is an idea raw material for producing water treatment chemicals such as Hydroxyl Aluminium Chloride and Poly-Aluminium Chloride, etc. In addition to the excellent acid-solubility, it has the properties of high efficiency, low cost, good performance, fast reaction and good filtration. Using Calcium Aluminate powder to produce water treatment agent by one step acid-soluble process is a unique invention in China. This technique can reduce much labor power and save electric power, then greatly low the production cost.
Testing method:
As per Calcium Aluminates for Water Treatment Chemicals of HG 3746-2004(2004/12/14)
Application: Mainly used for the material of producing aluminum sulfate, poly-aluminum chloride, crystal aluminium, and the substitute of aluminium hydroxide powder. Showing features of low price and high aluminium content.
Storage: In a dry place against moisture. Avoiding poisonous substance contaminated and to be exposed to heat and moisture during storage and transportation. Package must not be damaged.
Package: Packed in PP woven bag, net weight 50 Kg /bag.
