Abstract

This study was conducted with the objectives to analyze Ghee Mill effluents, search out low cost wastewater treatment and make the water suitable for irrigation. For this purpose Ghee Mill effluents were analyzed for 19 physico-chemical parameters twice, before and after treatment and were compared with Pakistan National Environmental Quality Standards (Pak-NEQS). The analytical results revealed that Total Suspended Solids (TSS), Chemical Oxygen Demand (COD) and oil & grease were high. For identification of suitable treatment method, two different techniques were tested, coagulation and adsorption. The optimum dose of 35mg/L to 66 mg/L was identified as appropriate to remove suspended solids. For adsorption a column containing 0.2 mg/L was identified as suitable dose for removal of color and COD. The analytical results after treatments were complying with Pak-NEQS. Therefore, coagulation in combination with adsorption is herein recommended for treatment of Ghee Mill effluents.
