Abstract

Aluminum chloride (AlCl3) is an inorganic coagulant and the preset study is aimed as surveying its usage for water treatment purposes. The keywords “poly aluminum chloride”, water treatment”, and “coagulant” were searched in Google Scholar, SID, Iran Medix, and Magiran databases between 2006 and 2017. The found articles were summarized afterward. The results showed that poly aluminum chloride (PAC) can be used as an effective coagulant if the standards with regard to concentration of PAC are observed in the process of treatment. PAC can be also used to remove extra fluoride content from water resources. To have better results, adjusting PH value of the coagulation process, avoiding higher doses of PAC, adequate stirring with proper speed (to facilitate coagulation process), efficient filtration (to remove aluminum clods), using chitosan (as aid coagulant of PAC), adding bentonites (to reduce optimum concentration of PAC needed) are recommended. © 2018, Advanced Scientific Research.
