STRATEGIES FOR AUGMENTING THE PENTACHLOROPHENOL DEGRADATION POTENTIAL OF UASB ANAEROBIC GRANULES

GUIOT S. R. / LANTHIER M. / TARTAKOVSKY B. / et al. - ARTICLE DE PERIODIQUE - 2002

Enrichment acceleration was attempted by applying an on-line control-based selective stress strategy to a native anaerobic upflow sludge bed(UASB) system, this strategy link pentachlorophenol(PCP) loading rate to methane production. The reactor biomass potential for PCP complete dechlorination reached a rate of 4mg/g volatile suspended solid/day with a period of 120 days. A pure culture Desul-fitobacterium frappieri, a strictly anaerobic Gram-positive bacterium was also used to augment the granular biomass of the UASB reactor.
