Abstract:
Background And Aims
Fluoride is released to environment naturally and via Industrial effluents. According to concentration of fluoride in potable water and its total uptake rate, can be beneficial or harmful. Due to simplicity of operation, easy access to the coagulants of alum and poly aluminum chloride and low cost, coagulation was selected for fluoride removal from water. The purpose of this study was to comparison the efficiency of alum and commercial poly aluminum chloride for fluoride removal from water.Methods
Lab scale experiments were carried out via Jar apparatus. Variations of this study, including pH, coagulant dosage and fluoride concentration were experimented in defined conditions.Results
Results indicate that optimum pH for both of coagulants was equal to 4. Concentrations of alum and poly Aluminum chloride for fluoride removal were 240 and 160 mg/L respectively and removal efficiency in optimum pH and dosage of coagulant were 84.2 and 84 % respectively.Conclusion
According to data obtained from this study, it can be stated that coagulation is a suitable method for removal of fluoride from water and poly Aluminum chloride is compatible with alum.Language:
