UPDATED Phosphorus Removal Guidance Module

This guidance module is designed to assist wastewater treatment plant (WWTP) personnel and stakeholders in understanding and optimizing phosphorus removal processes using low-cost operational strategies. The focus is on both Enhanced Biological Phosphorus Removal (EBPR) and Chemical Phosphorus Removal, with practical strategies for monitoring, diagnosing, and improving system performance. The information included in this module was obtained from available literature, EPA reports, practical experience and direct communication with practitioners actively working in the field. Tables, figures and diagrams were presented where appropriate for illustrative purposes. While this module provides a broad range of solutions, not all will be applicable to every treatment plant. The user can refer to several other documents mentioned in the ‘References’ section for detailed information.
