Faced with ever-increasing challenges, it is important for wastewater utility staff to proactively evaluate treatment plant performance and implement actions that improve operations, energy efficiency, and effluent quality. Self-Assessment for Wastewater Treatment Plant Optimization outlines the Partnership for Clean Water approach to achieving this objective, in as energy efficient a manner as possible. Suitable for wastewater treatment facilities in a wide variety of sizes and process configurations, this handbook guides users through the process of completing a comprehensive wastewater treatment plant self-assessment and creating an action plan framework to improve performance and efficiency- and achieve optimization.
