The results of anaerobic treatment of molasses processing wastewater in labscale AHR are presented. The performance of the model has shown that wastewater from molasses processing in BIOPO Leopoldov is suitable for anaerobic treatment. In the reactor, anaerobic granulated biomass was cultivated. As follows from granulation process observation, intensive wash-out of the suspended biomass started at Bv= 10-12 kg/m3d. This loading is significantly higher compared to the wash-out from UASB reactors with similar dimensions and technological parameters, as separation in the AHR filter layer is more effective than the separation in UASB gasliquid-solid separators. At Bv = 13 kg/m3d the operation of AHR was completed under the following parameters: hydraulic retention time =0.34 d, sludge concentration =26,4 g/1, COD removal =89%, effluent suspended solids < 100mg/l, and effluent COD about 500 mg/1.
