This study examines the possibility of using Polyaluminum Chloride (PACl) instead of Aluminum Sulphate (Alum) as a coagulant in surface water treatment process and compares between both coagulants at actual parameters ranges (Turbidity, pH, Temperature, and Residual Chlorine). The results indicated PACl is performing better than Alum.

Does polyaluminium chloride affect microbial community in urban river sediments?
Polyaluminium chloride (PAC) has been widely used as a chemical coagulant in water treatment. However, little is known about the impact of PAC performance on the microbial community in sediments. In this study, the archaeal, bacterial, and fungal communities in urban river sediments with and without PAC treatment were investigated.
What is high-purity poly-aluminum chloride (PACL)?
Poly-aluminum chloride (PACl) is one of the common coagulants for water and wastewater treatment. A new Chinese national standard of PACl has been implemented, where the concentration of insoluble substances, iron and heavy metals is to be controlled strictly, then researches on the preparation of high–purity PACl are needed.
Does PAC coagulant reduce turbidity of urban river water?
As a chemical coagulant, PAC exhibited high efficiency in removing particles and reducing the turbidity of urban river water, with a maximum efficiency of 98%. After the addition of PAC coagulant, the TDS, salinity, and residual metals in the sediment increased in an obvious manner.
Can coagulation remove pollutants from urban drinking water?
Conclusions In this study, the coagulation method, which is simple and cost-efficient, is proven as an effective process to remove pollutants from urban drinking water. Although several coagulants have been experimented with for urban drinking water treatment, the PAC coagulant was investigated as efficient for TOC, TSS, and TN removal.
Does high-purity PACL remove turbidity?
Samples taken from the Huangpu River were used to evaluate the coagulation performance of high-purity PACl in comparison with conventional PACl. The results demonstrate that for the whole dose range studied, high-purity PACls removed more turbidity than conventional PACl.
