Using a radial mixing anaerobic reactor a study was conducted to remove organics of septic tanks sludge of IPLT Sukolilo. The results showed that the granular sludge quality of the biofilm of reactor was important for the organic removal. The granular sludge must exist and grow during high organic loading. The reactor was able to remove 72.62 % and 89.64 % of COD and SS respectively at a detention time of 28 hours. The same removal of detention time of 2.8 hours was 62.64 % and 76.42 %. The reactor was able to cope with the organic shocks. The start-up process for bacterial growth was an important step to achieve such removal.
