Polyaluminium chloride for drinking water treatment
The raw materials used for potable water treatment and waterworks are different from industrial grade PCL. Aluminum hydroxide powder and calcium aluminate powder are used in both of them, which are produced through plate and frame filtration or spray drying. The indicators of potable water grade polyaluminum chloride produced by Wanlong Water Purification conform to the standard GB15892-2009. This product is widely used in drinking water treatment at home and abroad, water plant water treatment, by users welcome and attention.
Mechanism of action
Polyaluminium chloride is a kind of inorganic polymer coagulant. Its molecular formula is: ALn(OH)mCL(3N-M) 0 < M < 3N. Through the mechanism of compressing double layer, adsorptive electric neutralization, adsorptive bridge and sedimentation net, the fine suspended particles and colloidal particles in water can be destabilized, aggregated, flocculated, coagulated and precipitated to achieve purification treatment effect.
1, solid product appearance white, yellow, tan, reddish-brown powder, granular or flake;
2, dissolved liquid polyaluminum chloride product appearance: colorless or yellow transparent;
Potable water grade polyaluminum chloride product features
