✦ Synopsis

Four types of anaerobic upflow biofilters: non-packed (NP-AUBF), two-stage (2S-AUBF), multi-stage (MS-AUBF) and fully-packed (FP-AUBF), were tested for their start-up and operational performance characteristics. The volume of each filter was 12.1 dm 3 (10 cm I.D. x 155 cm in height).

Stepwise seeding was conducted and the effect on the reduction of COD and gas production was monitored. When each reactor was loaded with 2 and 4 kg COD/m3-day of synthetic waste simulating alcohol production plant, 2S-, MS-, FP-AUBF had treatment efficieneies of 89-93%, while NP-AUBF showed efficiencies lower than 50%. As a conclusion, 2S-or MS-AUBF can be used as efficiently as FP-AUBF, while the amount of packings in the former is half that in FP-AUBE
