Evaluation of Removal of Phosphorus by Poly Aluminum Chloride PACl Ferric Chloride from Wastewater Treatment Effluent Hasan Ali Mahdieh H mahdieh@Gmail com Date of Submission 22 Sep 2013 Department of Civil Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language Farsi Amir Taebi Harandi amirth@cc iut ac ir Abstract impacts as two ordinary coagulants in water and wastewater treatment industry on Phosphorus removal from wastewater treatment effluents This research was established on Isfahan north wastewater treatment effluent the optimum terms that cause be gain maximum removal of Phosphorus Samples were collected monthly for six months Results of analysis suggested optimum level for coagulant dose pH time and tensity of rapid mix time and tesity of slow mix and settle time Samples after collection was carried to environmental laboratory in civil engineering factually on Isfahan University of technology pH Turbidity COD total phosphorus and alkalinity was determined early In each experiment series did 18 tests according to orthogonal array witch suggested by Taghuchi method Then suggested levels were evaluated In total cases phosphorus When all of tests in six months completed Analysis of Variance ANOVA was established to identify of share ratio for each parameter in phosphorus removal process For each series of experiment a General Linear Model GLM was created with Minitab software Interactions effect between main parameters was assessed for generation of a good model too Totally impact of any parameter on removal of phosphorus specified with contraction of 6 models for each coagulant In cases of using Poly Aluminum Chloride coagulant dose settle time pH slow mix tensity slow mix time rapid mix tensity rapid mix time had ordinary share of 30 92 19 06 17 60 9 48 8 16 8 06 and 5 29 percent In cases of using Ferric Chloride the shares were different pH coagulant dose rapid mix time settle time rapid mix tensity slow mix tensity and slow mix time had share of 29 81 15 57 13 95 13 69 11 07 9 69 and 4 13 percent ordinary Maximum efficiency of phosphorus removal with poly Aluminum Chloride was 89 9 percent with residual phosphorus 0 1 mg l Also maximum efficiency of phosphorus removal with Ferric Chloride was 98 8 percent with residual phosphorus 0 4 mg l Impact of dosing Ferric Chloride on pH decrease was great Key Words Phosphorus Coagulation Flocculation Poly Aluminum Chloride Ferric Chloride Taghuchi
