Who Moved My Carbon? The Competition for Carbon at WRRF of the Future

Disruptive and game-changing approaches are needed to allow today’s wastewater treatment plant to evolve as a water resource recovery facility (WRRF) of the future. During a workshop at WEFTEC on Saturday, Samuel Jeyanayagam will explore the many uses of carbon at a WRRF including production of energy, volatile fatty acids for nutrient removal, and marketable chemicals.

Imagining a Day Without Water

Today, CH2M is proud to join elected officials, drinking water and wastewater providers, community leaders, business and labor groups, policy experts, advocacy organizations and infrastructure experts for Imagine a Day Without Water, a day specifically designated to educate the public about the water infrastructure crisis currently facing the United States.

Achieving Zero Liquid Discharge while complying with Effluent Limitation Guidelines

Curious to know how you can achieve zero liquid discharge at your facility? CH2Mer Tom Higgins will present the paper, “Enhancing FGD Wastewater ZLD Design and Insights from Simulated Brine-Solidification,” co-authored by CH2Mers Dennis Fink, Senior Project Manager and Krystal Perez, Senior Project Engineer, on Thursday, August 18, from 10:35-11 a.m., during the Power Plant Pollution Control and Carbon Management MEGA Symposium, in Baltimore, Maryland.

Recharging groundwater in the City of Fresno

Brian presented his paper, “Using Optimizing Modeling for Transmission Mains to Find Cost Savings for the Recharge Fresno Program,”at the American Water Works Association’s Annual Conference and Exposition, held June 19-22, in Chicago, Illinois. Brian’s presentation reviewed CH2M’s optimization model used to help the City of Fresno reduce overall costs of constructing a large conveyance system to alleviate its groundwater depletion. Brian also presented on “Developing a Regional Water Conservation Program for the Metropolitan North Georgia Water Planning District,” and “Incorporating Uncertainty in Water Demand Forecasts Increases Confidence,” in addition to moderating the session, “21st Century Water Conservation & Sustainability.”

Thermal Hydrolysis Offerings and Performance

The wastewater industry has entered an exciting time, as new technologies are making it economically feasible to exploit resources, such as sewage sludge, which has traditionally been considered a problematic waste. Today, with the advancements being made, sewage sludge is seen as a resource which can be recovered and used for its high energy and nutrient content. CH2M's Global Wastewater Service Team Deputy Leader Todd Williams explores a specific example of technology changing the way resources are recovered to help with managing biosolids - thermal hydrolysis technology.
