Polyaluminium chloride (coagulant) is a very complex compound. The change in the ratio HCO3/CO2 during coagulation cause a change in pH in the subsequent RO unit (because CO2 is not rejected by the RO membrane), and it was found that this change is constant for any given recovery, e.g. at 75% recove

This study evaluates the effectiveness of polyaluminium chloride (PACl) compared to aluminium sulphate (alum) and ferric chloride (FeCl3) to remove THM precursors and reduce THM formation potential of two samples (S1 and S2) from a surface water resource with low TOC (<3mg/l), high alkalinity (180 m
