Abstract:-Described in this study are experiments conducted to evaluate performance of fixed and suspended filter media in anaerobic reactor of compacted sewage treatment for domestic wastewater. Basically now a day’s compacted sewage treatment process is most preferred because of its advantages over septic tank for treating domestic wastewater. The media which used as fixed is graded stone media and for suspended media bioballs are used in two different reactors. The work involved laboratory scale batch reactor which is prime important stage of compacted sewage treatment. Two reactors are simultaneously observed over period of 180 days after development of biofilm over both filter media. The results are observed on the experimental basis with different condition. Suspended Filter media i.e. Bioballs gives 80% reduction efficiency in BOD whereas Fixed filter media gives approx. 70% reduction efficiency in BOD
