dc.description.abstractDairy wastewaters of strong acidic character from yoghurt and white cheese production units in small dairy plants were fed to sequential upflow anaerobic sludge blanket reactors. The reactors were monitored for organic matter removal, pH, HCO(3)(-) and volatile fatty acid (VFA) balance during the adaptation period. The wastewaters were rich in organic acids and fat as organic matter and deficient in nitrogen and sulfate. Rapid acidification lowered the pH consuming alkalinity provided in the feed solution. As one reactor configuration was not sufficient for efficient VFA and organic matter removal, second stage UASB reactors were configured into the system. Organic loading rates (OLRs) ranged from 1.12-1.33 g COD/L.d up to 5.3-6.5 g COD/L.d where the reactors' performance ameliorated with increasing OLRs after ammonia nitrogen and sulfate were added to the feed solution completing adaptation period in organic matter and VFA removal at the sequential mode in 71 days.en_US
