heal.abstract	The two most dominant technologies in sludge dewatering are belt filter presses and centrifuges. The objective of this work is to evaluate the two technologies in parallel operation, using full scale data from two wastewater treatment plants of different size. According to the data obtained, centrifuges produced a drier cake and exhibited slightly lower polymer requirements compared to belt filter presses. Based on a cost analysis performed, the annual sludge dewatering and disposal cost for a small to medium size and a medium to large size WWTP was higher for the belt filter press and ranged from 106-147 €/ton DS versus 82-114 €/ton DS for the centrifuge dewatering system. © 2009 DEStech Publications, Inc.	en
