| Abstract | The research reported herein was conducted to study the sources and characteristics of brewery wastewater and to evaluate the waste treatability by various .selected treatment processes. Major sources of wastewaters were wash water from various processes in the brewery. The pattern of the wastewater flows was found to be highly variable on both an hourly and daily basis and wastewater quality also varied. The brewery wastewaters studied were discharged through ten points. Three discharges were found to be very low in COD and BOD5 and needed no further treatment. The remaining wastewaters were combined for laboratory study of treatment by selected biological treatment processes, namely, batch and continuous activated sludge processes, anaerobic batch process and the two-stage anaerobic filter process. The combined waste had COD of 1,058 mg/l, BOD 643 mg/l and S.S. 221 mg/l. In the batch activated sludge process, more than 95% of the initial total filtered COD could be removed, whereas in the continuous flow activated sludge with 6 hrs retention the COD removal was as high as 96.6%. All design parameters were evaluated for the above processes. With regard to the batch anaerobic process, more than 80% as COD of the soluble organic matter could be stabilized, 88% and 94% as COD of the soluble organic matter were removed by the two-stage anaerobic process at the loading of 0.506 and 0.253 kg COD/m3 of effective volume per day, respectively. |
