Abstract
Attempts were made to utilize anaerobic hybrid reactor for sewage treatment. The reactor was seeded with digested sewage sludge and a HRT of 24 hrs. was kept in the start up. The HRT was subsequently decreased to 20, 16, 12, 8 and 4 hrs. A maximum COD removal efficiency of 74% was achieved at minimum HRT. The pH, alkalinity, solids and VFA of the effluent were within the permissible limits.
