| Abstract | The application of DSFF reactor to both two phase and single
phase anaerobic system was studied. The performance of DSFF
reactors in methanogenic phase, which received the different
organic acid as carbon and energy source, was also
investigated. The effect of phase seperation over single
phase system and the effect of different organic acid over
methanogenic efficiency was evaluated. One mixed flow reactor was
used as acidogenic reactor for two phase system and all reactors
were operated in 35 degree C temperature controlled room. Same
concentration (5000 mg/l) of glucose or acetic acid was used
in each system in order to make direct comparison. It was found
that DSFF reactor can be applied to both single phase and two
phase system with acceptable process performance. DSFF reactors
were very stable and tolerant to operational accident. Two phase
system has no significant advantage over single phase system
in this study. The methane fermentation by acetate alone failed
to maintain methanogenic enrichment whereas the bacteria
receiving the various organic acid other than acetic acid could
perform well. Type of material and architecture of supporting
media are very important functions for application of DSFF
reactor in anaerobic digestion process. The packing material made
with acrylic corrugated plastic sheet could not provide
the good biofilm attachment resulting in less process
performance than that of maximum obtainable one . |
