The development of this WERF anaerobic digester (AD) foaming guidance document is based on the need for a specific detailed methodology that water reclamation and recovery facilities (WRRF) personnel can follow and implement for management of their AD foam incidents. This guidance manual is the final product following a comprehensive effort research effort on AD foaming in full-scale WRRFs. It is the outcome of lessons learnt from extensive literature review, WRRF surveys, full-scale data studies and experimental analyses. The primary goals of this document are to: 1) serve as a practical and usable tool for WRRFs; 2) to present feasible alternatives that are cost-effective; 3) to present large amounts of practical, focused information in a concise manner; 4) to present information of sound technical and scientific basis that can become a standard or foundation for foam management in WRRFs.
