Study of Performance Evaluation of Uaa5 Reactor for Sugar Industry Effluent Treatment at Specific Temperature

Sugar industry waste water was treated in a laboratory model UASB reactor seeded with domestic waste water collected from septic tank sludge. Two different studies were carried out at Phase 1: maintained psicrophilic temperature (20-28℃) condition during October -November and Phase II: maintained mesophilic temperature (30-40℃) condition during April to June for COD reduction. In the phase I, the average varying influent COD applied over the model are 2114,2543,3341,4028 and 4520 mg/L with flow rates for each average influent COD are 4.80, 9.60, 14 40, 19.20 and 24.00 lid. It was found successful with 84.06% COD removal under the operating conditions of OLR at 0.034 kg COD/kg VSS day, VLR at 0.760 kg COD/m³ day and HRT at 5.21 days. In the phase II the average varying influent COD of 2065, 2508, 3332, 4033 and 4512mg/L were applied with same flow rates. The experimental work on UASBR model is found successful with 91.86 % COD removal under the operating conditions of OLR at 0.031 kg COD/kg VSS day, VLR at 0.764 kg COD/m3day and HRT at 5.21 days.
