Aluminum chloride, crystal

Molecular formula: ALCL3·6H2O
Technical standard: In conformity with China national standard.

Appearance: Colorless, brown or yellow crystal.

Product nature: Liable to be exposed to moisture, non-combustible, nontoxic, easily soluble in water, alcohol, ether and glycerol, aqueous solution show acidity, decomposition temperature of 100℃, and give out chlorine hydride when thermal decomposition.

Application:
Mainly used for treatment of drinking water, and make better effect especially for the treatment of low temperature, low turbidity and alkaline water. Also the intermediate product for manufacturing polyaluminium chloride for the substitute of hydrochloric acid, which can reduce pollution.

Production process of manufacturing liquid PAC with Crystal aluminum chloride
Crystal aluminum chloride- Water dilution- Calcium aluminate powder- Polymerisation- Finished liquid product

1 ton of Crystal aluminum chloride, mixed with more or less 700 Kg calcium aluminate powder, can yield 6-7 tons of 8-10% liquid PAC.

Features:
1. Free from water, dust and atmosphere pollution, for use of crystal aluminium chloride instead of directly using of hydrochloric acid.
2. Uses of crystal aluminium chloride yield less offscourings than other materials such as bauxite, aluminium powder, etc., which can decrease labor content and increase production efficiency.
3. Less production procedure, decrease production energy consumption, and reduce cost.
4. Owing to adopting low temperature, normal pressure polymerization, intrinsic activity of crystal aluminium chloride are maintained, which make it bear the features of adaption to wide water area, less dosage (less more or less 20% than ordinary reagent), yielding less sludge, lower cost of water treatment, larger flocs, quick sedimentation, better adation to the abrupt change of raw water turbidity and flow.
