An experiment of anaerobic biofilter using honeycomb plastic media was conducted in semi-pilot scale. This paper describes the pilot plan study of chickenâ€™s slaughterhouse wastewater treatment using anaerobic and aerobic submerged biofilter using honeycomb plastic media. The main research was conducting by continuous operation under condition 4 days, 2 days and 1 day retention time. The result of experiment shows that within the anaerobic process under conditions 1- 4 days retention time, the removal efficiency of COD were 78 â€“ 87 %, BODÂ were 78 â€“ 89Â Â %, 73 â€“ 83 % , and Total Suspended Solids (TSS) were 83 â€“ 96 %Â respectively.Â
Using combined anaerobic and aerobic process under same conditions 1 - 4 days retention time shows increasing of removal efficiency.Â The removal efficiency of COD were 86 â€“ 90 %, BOD were 85 â€“ 90 %, Organics (KMnO4) were 81 â€“ 88 % and Total Suspended Solids (TSS) were 94 â€“ 96 % respectively.Â The longer retention time has resulted in higher removal efficiency.
