Daftar Isi:
- This study was aimed to 1) compare effectiveness of aerobic and anaerob biofilters in reducing BOD5, COD, and Total Nitrogen levels, 2) examine the interaction between immersion times and biofilter medium in reducing BOD5, COD and Total Nitrogen levels. This study was an experimental study using biofilters of brick fraction and data analysis was permormed using ANOVE tes. Study result indicated that anaerobic and aerobic biofilters medium were effective in reducing BOD5, COD and Totall Nitrogen levels. In anaerobic process with contact time 1 and 2 weeks, the BOD5 was reduced up to 90,48% and 93,33%, COD 83,31 % and 88,31%, and Total Nitrogen 5,40% and 30%, respectively. Where as in the combination of anaerobic and aerobic process with immersion time 1 and 2 weeks, elimination total of BOD5 level was 92,16% and 98,53%, cod 87,79%, and 89,16% and Total nitrogen was 5,94% and 37,83% elimination, respectively. The reduction of BOD5, COD, Total Nitrogen in this study was significant at immersion time of 1 and 2 week (p=0,000).
