Abstract
This report studies the effects of chemical conditioners on dewatering sludge through
geotextiles. An optimum chemical conditioning dosage is determined for the
sludge at the Fredericton Area Water Pollution Control Commission Wastewater
Treatment Plant (Frederiction W.W.T.P.). A model is developed for predicting the
solids content in a sludge-cake after dewatering. Finally, the results obtained from this
study are applied to a design example to investigate their applicability to a small to
medium sized municipality in dewatering sludge.
