Spentwash was pretreated with 4.5 Litters capacity anaerobic floating bed baffled wall reactor. Reactor is used to obtain a treated Spentwash on which adsorption experiment was carried out. Adsorbent used was activated Bagasse. Its adsorptive properties were determined by using standard Melanoidin solution which was synthesized in laboratory. Adsorbents showed a best fit for Langmuir isotherm undergoing monolayer. A 10 g dosage and 90 min contact time was chosen as optimum value. Rector performed well and shown 69 % efficiency in removing COD at 2000 mg/L COD loading rate at 24 hr of HRT. Adsorption experiment had shown 40% efficiency in reducing Melanoidin concentration and 68.9 % efficiency in reduction of color from treated spent wash. Combined treatment of Spentwash in anaerobic floating bed baffled wall reactor and adsorption resulted in 81 % efficiency in treating COD load at 2000 mg/L COD loading rate at 24 hr of HRT.
