چکیده مقاله
The aim of the present study was to explore the possibility of using the downflow filtration process using multi media filters as a good alternative to the reuse of wastewater from the wastewater treatment plant of Baharan Industrial Town, Hamadan, Iran The experiments were carried out with a pilot scale reactor and three variants of the filter medium including Garnet, Silica, and Anthracite To achieve the aims of the present study, the effectiveness of three different coagulants including poly aluminum chloride PAC , sulfate aluminum Alum , and ferric chloride FeCl3 were investigated Different operational parameters, i e , turbidity, TS, TSS, TDS, COD, BOD5, TP, and heavy metals were investigated before and after filtration The results indicated that the best coagulant for the coagulation process was alum the concentration of 400 mg/L Also, the maximum removal efficiency of turbidity, TS, TSS, TDS, COD, BOD5, and TP were 96 99 0 6, 25 64 3 6, 97 02 0 6, 19 31 3 9, 80 89 3, 81 6 3, and 83 20 2 14% at a surface load of 5m/hr after contact time of 6 hr, respectively The maximum removal rate of heavy metals was 58 9% after 9 hours of filter operation at a surface load of 5 m/hr The use of a direct filtration process with multi bed filters could provide the possibility of use of the wastewater treatment plant effluent of Baharan industrial town in agriculture so that this effluent can be employed as a water resource
