Abstract:

Little substantive change in the way municipal waste water sludges are managed occurred during the 20th Century – current practices differ only marginally from those used in the 19th Century. Further marginal improvement in current sludge treatment practices is not a worthy goal for the 21st Century; a more challenging and meritorious goal is to develop sludge management as a sustainable practice. Substantial advances in separation technology are needed to achieve this goal.
