Effect of the addition of bentonite on the anaerobic biodegradability of solid fatty wastes

The biological degradation of solid fatty residues is limited by their low bioavailability. In this work, the effect of the day mineral bentonite on the degradation of hexane extractable matter and its conversion to volatile fatty acids was investigated. Our results showed that the best performance...

520			\|a The biological degradation of solid fatty residues is limited by their low bioavailability. In this work, the effect of the day mineral bentonite on the degradation of hexane extractable matter and its conversion to volatile fatty acids was investigated. Our results showed that the best performance in the elimination of hexane extractable matter (73% +/- 2.5) and the production of volatile fatty acids (39% +/- 1.5) were observed in continuous experimental assays with a bentonite/greases ratio of 0.9. Isotherm studies showed that the sorption equilibria of oleate on bentonite and sludge could be described by the LANGMUIR model
