Water Environment Research Open Access Article Examines Thickened Waste Activated Sludge

ALEXANDRIA, Va. – The open access article in the September 2018 issue of Water Environment Research investigates the unbiodegradable fraction of particulate chemical oxygen demand (PCOD) in thickened waste activated sludge. “In their paper on thickened waste activated sludge, Chowdry et al. used long-term anaerobic studies operated at detention times between 16.7 – 33.3 d (corresponding to organic loading rates of 1.21 – 3.47 kg/L m^3) to determine the fraction of unbiodegradable particulate COD,” said Tim Ellis, WER editor-in-chief. “They found a value of 0.28 which agreed well with the fraction of unbiodegradable volatile suspended solids that was determined to be 0.26.

 

This study provides additional information for the design and operation of anaerobic digestion processes to achieve volume reduction, pathogen destruction, and energy recovery from waste active sludge.” Selected WER articles such as this one are available free to the public on a monthly basis through an open access program. In addition, authors can pay a fee to make their accepted articles open access.
