There are various grades of Polyaluminium chloride in the market with varying degrees of Al2O3 concentration- usually 10-20% for liquid type, 28-31% for powder PAC. While choosing which grade to use, there are other factors beside the concentration of aluminum to take into consideration.
Commercial grade PAC products tend to have a higher degree of basification. This is the degree of concentration of Hydroxyl groups relative to aluminum ions. As a rule of thumb in PAC usage, the higher the basicity, the higher the efficiency, cationic charge density, and polymer value.
Poly Aluminium coagulants are increasingly finding their way into portable water treatment plants. In several instances during post-treatment pH adjustment, usage of alkali proved to be unnecessary. This has a positive effect not only on the quality of water but also on savings on production costs and maintenance requirements.
