Performance of an Up-Flow Anaerobic Sludge Blanket Reactor (Uasbr) In the Treatment of Brewery Effluent
Journal Title: American journal of Engineering Research - Year 2018, Vol 7, Issue 5
Abstract
Brewery waste stream is a high biodegradable with BOD in the range of 2500 to 3500 mg/l and COD from 4600 to 7000 mg/l. This waste stream suffers substrate inhabitation in conventional biological treatment process. Up flow anaerobic sludge blanket reactor (UASBR) is versatile and proven to be a high rate anaerobic reactor. The substance of the sludge blanket which is more dependent on the biodegradability and nutrients offers an edge for treating highly biodegradable waste stream such as brewery. The present study evaluated the performance of UASBR through a laboratory model (25 liters of effective volume) for treating the brewery effluent. This model was studied for its treatment efficiency in terms of COD reduction. The experiment was conducted for varying influent COD 3227, 4332, 5180, 5748, 6191, 6662 and 7177 mg/l with corresponding flow rates of 7.20, 14.40, 21.60, 28.80 and 36.00 mg/d . This work on UASBR model for treating brewery waste stream was found to be successful with COD removal of 79.85 % for the operating conditions of OLR at 0.0922 kg COD kg VSS per Day and HRT at 3.47 days.
