poly aluminum chloride vs alum keyword found website
PAC vs. Alum? What are the key differences to consider?
These highly polymerised coagulants include the following: ♦ polyaluminium chloride (PACl, n=2 and m=3), ♦ aluminium chlorohydrate (ACH, n=2 and m=5), and ♦ polyaluminium chlorohydrate (PACH): similar to ACH.

Comparison of Three Aluminum Coagulants for Phosphorus Removal
to 80%, followed by aluminum chloride and aluminum sulfate. The lowest proportion of alumi-num quality to phosphorus quality is 63 as using poly aluminum chloride, followed by aluminum chloride and aluminum sulfate. It is suggested that the poly aluminum chloride should be the best option to remove phosphorus in water plant. Keywords

99.0% for alum and 93.8-99.6% for poly-aluminum chloride over the applied range of turbidity. Both applied coagulants demonstrated promising performance in tur-bidity removal from water; however, poly-aluminum chloride showed better per-formance compared to aluminium sulfate. The results of the current study can be

“Inorganic Polymer Flocculation Catalyst”—Polyaluminum
results show that the average residual aluminum in the PA-WTS was 3.4 mg/L. These are much lower doses than what has been used in other studies using alum, for example it was 313 mg Al/L alum sludge for Horth et al. (1994). One of the the advantages of using pre-polymerised inorganic coagulants over alum, is their

treated with alum. High levels of aluminium in potable water is reported to cause Alzheimer’s disease, a form of senility. However uptill now there is no clear evidence to suggest a link between aluminium & Alzheimer’s disease (Cole, 1990).

6. Lower doses are required to give equivalent results to alum. 7. The increase in chloride in the treated water is much lower than the sulphate increase from alum, resulting in lower overall increases in the TDS of the treated water. PAC=PACl. Note: a) .the cost of Poly Aluminium Chloride is twice/thrice of Alum ( roughly the cost of PAC-$0.4/ Kg)
