The Use Of Flocculants In Anaerobic Digestion Of Palm Oil Mill Effluent
The use of flocculant in the anaerobic digestion of palm oil mill effluent (POME) was studied. The use of flocculant had enabled pelletization in mesophilic anaerobic digestion to occur within three months of start-up for the substrate which is difficult to granulate naturally. The effect of pell...

| description |
The use of flocculant in the anaerobic digestion of palm oil mill effluent
(POME) was studied. The use of flocculant had enabled pelletization in mesophilic
anaerobic digestion to occur within three months of start-up for the substrate which
is difficult to granulate naturally. The effect of pelletization had resulted in an
increase in biomass concentration and produce a good-solid-liquid separation within
the digester resulting in enhanced treatment performance and the ability to tolerate
higher organic loads.
Various flocculants were initially tested to assess their effectiveness in
forming flocs which exhibited good settling properties with no inhibitory effects on
the anaerobic digestion of POME. Zetag 88N, a cationic polyacrylamide of high
molecular density was found to be the most effective flocculant. Once pelletization
occured, flocculant dosage was able to be discontinued without affecting the process
performance. |
