CHEESE WHEY TREATMENT BY HYBRID UASB

Sanmati Bedage*

ABSTRACT

Utilization of cheese whey is a major concern nowadays which creates many environmental problems. Characterization study of whey effluent for Color, Total Suspended Solid (TSS), pH, BOD, COD, Sulphates, Alkalinity was performed. Raw whey was given the primary treatment of coagulation by using FeCl3 as a coagulant and secondary treatment by hybrid UASB (UASFF). The lab scale potential of UASFF for pretreated whey effluent was assessed for the organic loading in the range of 0.5 to 6 kg COD/ m3. d. The HRT is also varied in the range of 8, 20, 24 and 48 hrs. The influent and effluent were analyzed for the parameter for Total Suspended Solids, Total Dissolved Solids, pH, Alkalinity, Sulphates, Volatile Fatty Acids, COD and BOD. UASFF system is efficient to treat whey effluent with average COD removal efficiency of 88% at an organic loading of 4 kg/m3.d at 20 hrs HRT.
