Project Abstract

The work will evaluate the effects of enzyme additions on the dewatering properties of sludge produced in a bench-scale anaerobic digestion study. Sludge will be produced by two bespoke 10L anaerobic digesters at IT Sligo. A controlled fermentation experimental setup will allow for manipulation of variables such as retention time and feed-stock composition. Comprehensive trials will then assess the effects of various combinations of key enzymes on key dewatering parameters. These parameters will include permeability compressibility and optimum conditioner dose. The aim is to determine an optimal combination of enzymes for enhanced sludge dewatering leading to scaling up to pilot-level.
