Updating the Comprehensive 1979 Sludge Treatment & Disposal Manual

Wastewater treatment plants produce residuals (as sludge) that must be managed, which represents more than 50% of the total cost of wastewater treatment. As Office of Water (OW), OIG, Congress, and state authorities have noted, utility companies need help selecting cost-effective solutions for sludge management.

Chapters in the current manual include:

Design Approach;
Wastewater Solids Production and Characterization;
Thickening;
Stabilization;
Disinfection;
Conditioning;
Dewatering;
Heat Drying;
High Temperature Processes;
Composting;
Transportation;
Storage;
Sidestreams from Solids Treatment Processes;
Utilization; and
Disposal to Land.

Working closely with Office of Waste Management (OWM) and consultants, EPA will review the chapters to determine their current relevance and applicability in light of other EPA documents. Chapters will be selected to remain unchanged, be updated, or be added; a Request for Proposals (RFP) for individual chapters will be sent to authors who will prepare drafts.
