Dewatering Municipal Wastewater Sludge

Describes dewatering processes for municipal wastewater sludge. Up-to-date information is provided which a design engineer or others involved in the decision making process for sludge treatment can use to select appropriate dewatering processes for particular applications. The object is to reduce sludge volume, producing a sludge that behaves as a solid, not a liquid, and subsequently reducing the cost of treatment and disposal.
