Researchers investigated the unbiodegradable fraction of particulate chemical oxygen demand (PCOD) in thickened waste activated sludge (TWAS). They used semi-continuous completely-mixed anaerobic digesters for the study. A laboratory-scale system was operated at detention times ranging from 16.7 to 33.3 days with organic loading rates between 1.21 and 3.47 kg/L m3. The article, “Estimation of the […]
