Wastewater Engineering: Design of Water Resource Recovery Facilities (MOP 8 Series) provides the reader with the up-to-date knowledge and tools required to design water resource recovery facilities. It serves as both a textbook for senior level and graduate students in civil engineering and a reference work. The scope of coverage and the classroom-friendly features, such as learning objectives and example problems, makes it an excellent tool for students transitioning from academia to practice, and it remains an essential resource for practitioners. Written by a team of professors and consultants and put through a rigorous industry review, Wastewater Engineering provides vital WRRF design information to an engineer at every stage of their education and career. Wastewater Engineering has its roots in WEF’s Design of Water Resource Recovery Facilities (MOP 8), a long-time fixture on the design engineer’s shelf. As WEF approached how to update MOP 8, the organization decided to do so in a way that would address two significant needs in the water sector. The first was the need for current, nationally applicable, peer-reviewed design standards. The result was Standards for Design of Water Resource Recovery Facilities (WEF 8). WEF 8 is a tool for seasoned design professionals, providing concise coverage of critical design criteria that has been formatted in quick-reference tables and bulleted lists. The second was the need for a wastewater design textbook and reference, as covered by this book. Within the MOP 8 series framework, this textbook serves as the entry point for new wastewater engineers and a primary reference work for practitioners, providing both theory and significant context behind the design parameters covered more briefly in WEF 8.

Description: Per- and Polyfluoroalkyl Substances (PFAS): A Blueprint for Utility...

This Blueprint represents a moment in the evolution of the PFAS story, noting that this is an iterative process in tracking PFAS. This publication targets a specific audience and purpose: utilities navigating options for addressing PFAS. Because PFAS continues to be a moving target, it adds a level of complexity in offering the latest detail. This publication offers a good historical snapshot of the considerations utilities need to make when preparing their strategies. It's important for receivers of these compounds to be informed about PFAS and to be able to effectively communicate to their customers. This Blueprint document presents best practices and resources for receivers trying to navigate PFAS issues in their communities.

WEF’s new, comprehensive toolkit provides an extensive framework for communicating about biosolids in ways that are factual, science-based, and easily understandable by those who might be hearing about biosolids for the first time. The toolkit includes guidance on some of the more challenging communication tasks you may encounter—responding to, or proactively pursuing media coverage, handling concerns raised about the safety of biosolids, creating presentations for use at events or meetings with the public, and developing content to post online or on social media. The toolkit features messages that serve as an overall umbrella that can be adapted for FAQs, talking points, community meetings, fact sheets, brochures, social media, and websites.

Plus, listen to WEF’s webcast on how to use the toolkit!

Abstract

Water Environment Federation (WEF) members know the significance of the use of biosolids to wastewater treatment and to the communities we serve. The benefits are obvious but not always without controversy. Our member volunteers have done a significant amount of work to elevate the conversation about what biosolids bring in terms of innovation, resource recovery, and stewardship, and we think you’ll agree that this work is even more important in today’s environment.

This biosolids communications toolkit builds on and expands the digital resource developed by WEF and can be used by WEF members to help raise awareness and support for the use of biosolids. This is a resource for communicating about biosolids in ways that are factual, science-based, and easily understandable by those who might be hearing about biosolids for the first time—your neighbor, a city council member, or your mom.

The toolkit includes guidance on some of the more challenging communication tasks you may encounter—responding to, or proactively pursuing media coverage, handling concerns raised about the safety of biosolids, creating presentations for use at events or meetings with the public, and developing content to post online or on social media. The toolkit features messages that serve as an overall umbrella that can be adapted for FAQs, talking points, community meetings, fact sheets, brochures, social media, and websites.

Think of this toolkit as a do-it-yourself handbook designed for the range of utility professionals who may need it. Some may want to follow all the step-by-step guidance the toolkit offers while others may only need specific sections. You are encouraged to use this as a reference any way you need, to address any number of issues related to biosolids, to create messages, to see samples for best practices, and more.

WEF members and water professionals around the world are incredibly proud of the services they provide and know biosolids are part of their
innovative industry’s future. This toolkit, and the accompanying training, will help make you proficient at communicating all that biosolids can do, as you share how valuable this resource is.

Polymer/Flocculants 101

The aggregation of particles into larger and more easily removable forms by employing coagulants or flocculants is necessary for efficient separation by clarification, sedimentation, filtration, or dewatering processes. The terms “coagulant” and “flocculant” are often used interchangeably. However, the discussion in this fact sheet will be focused on high molecular weight, cationic polymeric flocculants used for thickening and dewatering solids separation processes where they operate through bridging or similar mechanisms
