Polyaluminum Chloride (PAC)
Recently, a number of alternative aluminum-based coagulants have been developed for water treatment applications. Totally soluble in water it has a formula (Aln(OH)mCl(3n-m))x .
Polyaluminum chloride is also used in deodorants and antiperspirants. It has also special use in drilling mud treatment.
High basicity polyaluminum chloride is available on request.
Pride-Chem can provide polyaluminum chloride in the following UN packaging:
- 200L drums
- 1000L IBCs
An important property of polyaluminum coagulants is their basicity. This is the ratio of hydroxyl to aluminum ions in the hydrated complex and in general the higher the basicity, the lower will be the consumption of alkalinity in the treatment process and hence impact on pH.
The polyaluminum coagulants in general consume considerably less alkalinity than alum. They are effective over a broader pH range compared to alum and experience shows that PAC works satisfactorily over a pH range of 5.0 to 8.0. PAC produces less sludge than alum counterpart.
