liquid or powder Aluminium ACH chloro hydrate easily dissolved in water
#
Aluminum Chlorohydrate (short name is ACH) is Aluminium-based Coagulant , the most concentrated material of the PAC family, it offers the maximum alumina and basicity available in a stable solution form. ACH liquid is typically defined as at least 23%min Al2O3 and 83% basic. As it has the highest polynuclear content and highest level of neutralization, it can deliver the benefits of PAC to the ultimate degree.

#
ACH is a workhorse product in drinking water and industrial wastewater applications, as it can provide performance across a wide variety of water conditions. With it& acute;s high alumina content, it is the least freight sensitive of any of the PAC products.


Physical and chemical properties:

Inorganic macromolecular compound; white powder, its solution shows colorless or tawny transparent liquid and specific gravity is 1.33-1.35g/ml (20℃), easily dissolved in water, with corrosion.
