| Abstract | The carpet wastewater characteristics from different point sources namely sump, washing and dyeing were studied. Acid and basic dyes were the main dyes used in the dyeing processes Dyeing wastewater contained maximum amount of COD, Color and TSS. The acid dye wastewater contained average COD as 920 mg/L having average color, 309 ADMI. The basic dye wastewater contained average COD as 984 mg/L having average color, 302 ADMI. Acid dye and basic dye wastewater samples were treated by electroflotation process as well as Activated-sludge process separately but couldn't satisfy the effluent standards. Chemical treatment (Alum) of acid dye wastewater could only remove 30.19% COD. Acid dye wastewater could be well treated by electroflotation process followed by ASP in SBR and satisfy the effluent standard. The overall COD removal 97.10% and 91.92% color removal efficiency could be achieved by producing final effluent COD as 29 mg/L and final color 32 ADMI at the energy consumption of 1.12 Kwh/m3 in EFR and ASP in sequencing batch process running for 6 hours with F/M ratio as 0.202 day-1 . Basic dye wastewater could be well treated by ASP in sequencing batch process followed by EFP and satisfy the effluent standard. The overall COD removal 94.40% and 68.67% color removal efficiency could be achieved by producing final effluent COD as 58 mg/L and final color 94 ADMI by ASP in sequencing batch process running for 8 hours with F/M ratio as 0.248 day-1 at the energy consumption of 0.200 Kwh/m3 in EFR. |
