Sludge drying reduces water content by vaporization of water to permit sludge grinding, weight reduction, and to prevent 2-3 . continued biological action. The moisture content of dried sludge is less than 10 percent. Incinerator ash is a product of the incineration of sewage sludge. Ash is therefore not covered under the sampling or analysis of sewage sludge. It is covered under RCRA Subtitle

ZebraTube dewatering bags use woven polymer fabrics as semi-permeable membranes to trap the solids inside. The sludge is pumped in and the geotextile acts as a filter, allowing water to pass through but retaining the solid matter. When the tube has filled and completely drained, the solid material is dry enough to remove or re-use.
