  • Evaluation of Combined Heat and Power Technologies for Wastewater Treatment Facilities (PDF) (213 pp, 8.37 MB) Exit EPA Disclaimer - This report on combined heat and power (CHP) was prepared by Brown and Caldwell for Columbus Water Works (CWW) under an assistance agreement awarded by U.S. EPA to CWW in support of the Columbus Biosolids Flow-Through Thermophilic Treatment (CBFT3) National Demonstration Project in Columbus, Georgia. The document serves as a planning-level tool for wastewater professionals and provides an examination of commonly used and emerging CHP technologies for converting anaerobic digester gas to electrical power and process heat. It provides detailed technical information about existing technologies for producing heat and power from biogas including: internal combustion engines, gas turbines, microturbines, and fuel cells as well as other beneficial uses for digester gas. The report includes detailed process descriptions and performance and cost data. It also addresses factors such as infrastructure requirements, digester gas treatment, and operational issues. The report also includes five in-depth facility case studies, including four projects in California (projects at the Joint Water Pollution Control Plant in Carson, the Point Loma Wastewater Treatment Plant in San Diego, the Lancaster Water Reclamation Plant in Los Angeles County, and the Riverside Water Quality Control Plant in Riverside) and one in Wisconsin (the Sheboygan Regional Wastewater Treatment Plant in Sheboygan), as well as a chapter featuring detailed information about the full-scale CWW CBFT3 project in Columbus, Georgia, that demonstrates successful biogas-to-energy projects.
  • Evaluation of Energy Conservation Measurers for Wastewater Treatment Facilities  (PDF) (224 pp, 4.18MB) This technical document will assist municipal utility owners and operators in finding information on cost-effective energy management and energy conservation measurers (ECMs) and technologies for reducing total energy usage in their wastewater treatment facilities.  The document presents technical and cost information about energy management and cost-effective energy conservation measurers and technologies.  Technical and cost data were developed from literature sources, as well as, from manufacturers and operating facilities contacted as part of this project.  The document provides preliminary information on innovative and emerging ECMs and technologies that have the potential for substantial energy savings.  In addition, the document includes nine in-depth facility studies that further examine the application and cost information for various full-scale, operational ECMs and technologies.  
  • Municipal Nutrient Removal Technologies Reference Document
    This reference manual will help municipal utility owners and operators, state permit writers and regulators plan cost-effective nutrient removal projects for municipal wastewater treatment facilities.
    • Volume 1 (PDF) (268 pp, 4.1MB) - Detailed technical and cost information about both biological and physiochemical treatment technologies. It includes detailed process descriptions and operating factors for processes that can remove nitrogen, phosphorus, or both from municipal wastewater. Also includes data on process performance and reliability
    • Volume 2 (PDF) (181 pp, 9.96MB) - Nine in-depth facility studies that examine the factors involved in successful process design and operation, and cost analysis.
  • Emerging Technologies for Wastewater Biosolids Management (PDF) (133 pp, 1.51MB) - This guide will help municipal wastewater treatment system owners and operators find information on emerging biosolids management technologies. Featured technologies can be used to reduce the volume of residuals to be managed, produce stabilized biosolids that can be used to help improve soil fertility and tilth, or promote the recovery of energy from biosolids. Technical and cost data for more than sixty technologies are provided. An additional 25 early-stage technologies are also identified.
  • Emerging Technologies for Conveyance Systems: New Installations and Rehabilitation Methods (PDF) (98 pp, 752K) - This technology guide is intended to help municipal and utility collection system owners and operators find information about innovative and emerging technologies for the installation of new conveyance systems and the repair of existing systems.  The guide also includes data on cost-effective technologies for repair and rehabilitation of existing conveyance systems and preliminary information on emerging technologies for new installations and for the repair of existing conveyance systems.
  • Overview to Watershed Assessments: Tools for Local Stakeholders (PDF) (29 pp, 667K) - The Watershed Management Framework provides for comprehensive, sensible water resource decisions and strategies, and addresses more effectively the full range of stakeholder concerns. The assessment phase is one of the first elements of effective water resources management. This document provides a set of tools to support watershed-level frameworks to conduct the assessment phase.
