Abstract

Treatability tests of.instant coffee industry wastes were run in a lab scale upflow anaerobic sludge blanket reactor, during five months. A minimum hydraulic retention time of 2.1 days was attained. The results obtained in two average conditions indicated a gas yield of about 0.3 NrtJ.3/kgCOD added, containing about 75% of methane, as well as a BOD removal about 90%. From these data a good performance of the treatment system can be predicted at very short hydraulic retention times.
