Comparison of three practical processes for purifying wine distillery wastewaters

, : Comparison of three practical processes for purifying wine distillery wastewaters. Process Biochemistry 25(3): 93-96

Wine alcohol distilleries produce 8 volumes of high strength waste (vinasses) from every volume of ethanol. This waste has an acidic character and a high organic content (20-25 g/litre C.O.D.). Aerobic, mesophilic anaerobic and thermophilic anaerobic treatments were compared for the reduction of vinasses strength. The processes were studied to optimize operating conditions of each process in order to achieve an adequate purifying performance.
