Treatment of winery effluent with upflow anaerobic sludge blanket (UASB)--granular sludges enriched with Enterobacter sakazakii.
Three upflow anaerobic sludge blankets (UASBs) were evaluated for the treatment of winery wastewater: the first was seeded with granular sludge enriched with Enterobacter sakazakii and reached a 90% COD removal within 17 d at hydraulic retention time of 24 h; the second was seeded with brewery granules and achieved 85% COD removal within 50 d, the third was seeded with just sludge and showed the typical problems encountered with conventional sludge seeding and had continuously to be re-seeded. A PCR-based technique was developed for the rapid detection of E. sakazakii in the granular sludge.
