“…According to Alizadeh and colleagues study, by increasing pH the matter coagulation increases [41].According to the study by Yousefi et al, optimal pH for poly-aluminum chloride (PVC) is 7.5 to 8 which is suitable for drinking water [42].Takdastan and colleagues study showed that the highest average percentage of turbidity removal in the use of poly aluminum chloride at pH = 8 is 93.3 percent, The more quickly mixing rapid, the higher turbidity removal efficiency, and by adding a coagulant in water leads to a drop in pH from 8 to 7/84 [11].Bina and colleagues also showed that the optimal pH for the removal of turbidity using ferric chloride coagulants is 7. [43] Conclusion: according to the conducted studies, it concluded that the use of chemical coagulation is an effective way to reduce water turbidity and the use of poly aluminum chloride due to low sludge production, PH reduction to a limited extent, the creation of large fluke and high rate of sedimentation and less residual in water is more than any other coagulants.…”

Health promotion and protection of environment constantly depends on providing clean water. Water turbidity caused by suspended particles and colloids in it. So the aim of this study was to review the efficiency of chemical coagulation in removal of water turbidity .In this study all the present articles were searched in internal databases including Iran medex, Irandoc and SID and external databases such as Google Scholar, Scopus, Science Direct, scientific database of World Health Organization (Medicos / WHO / EMR), free journal access guide (Open Access Journal Directory of), PubMed using the Key words of coagulants, chemical coagulation, total water turbidity, the articles were searched and 268 articles were extracted and 25 articles that were completely relevance with the topic was reviewed. Including inorganic polymer coagulants advantages of high efficiency compared to conventional coagulants extensively in a range of pH, and better performance at various temperatures, especially at low temperatures is the Among the advantages of polymeric inorganic coagulants efficiently compared to conventional coagulants is appropriate efficient in an extensively range of pH, and better performance at various temperatures especially at low temperatures.Based on the studies, it was concluded that the use of chemical coagulation is an effective way to reduce water turbidity and the use of poly aluminum chloride due to low sludge production, reduction of PH to a limited extent, creation of large fluke , less residual and high rate of sedimentation in water is greater than other coagulants.
