A laboratory study was conducted to assess the performance of a Hybrid Upflow Anaerobic Sludge Blanket (HUASB) Reactor in order to treat the effluent from a paper mill. The maximum organic loading rate (OLR) is 12 kg COD/m3.day. The OLR was calculated on the basis of COD inlet in the reactor for different flow rates. A hydraulic retention time (HRT) of 12 hrs was maintained in the reactor. The maximum TCOD and SCOD reduction was 92% and 88% respectively. The maximum biogas production was 3.27 m3/m3.day. Development of granulation with two different inoculums in early start-up was also studied. The study revealed that earlier start-up and granulation of biomass could be achieved using mixed sludge (cow dung and effective microorganisms). Scanning Electron Microscope (SEM) study of the granules showed predominance of Methanosarcina and Methanothrix type of species on the surface of granules. The process efficiency and biogas production were found to be increased with an increase in the organic loading rate. The size of the granules was 1-3 mm and exhibited good settling tendency.Keywords
