December 13 – 15, CH2Mers Mike Bobinecz and Tom Higgins will share their expertise in Water for Power at the 2016 POWER-GEN International Conference in Orlando. Both Bobinecz and Higgins are authorities on the U.S. Environmental Protection Agency (EPA) revised Steam Electric Power Generating Effluent Guidelines (ELGs) and will be featured in a special session dedicated providing comprehensive strategies to comply with the ELG’s, specifically as they relate to flue gas desulfurization (FGD) systems.
Mike Bobinecz will chair the session and Tom Higgins will discuss how to achieve FGD wastewater treatment compliance through design details.
For background, on September 30, 2015, the EPA promulgated its revised ELGs, which impose new steam electric plant wastewater discharge limits for arsenic, mercury, selenium, and nitrates. The revised rule sets the first federal limits on these parameters requiring adoption of new wastewater treatment technologies.
These recent revisions to the Steam Electric Utilities ELGs include requirements for the treatment of wastewater produced from wet FGD systems. Due to the complex chemistries associated with the wastewater generated from these systems, various treatment processes and equipment must be evaluated to reduce the regulated constituents to the permitted levels. Numerous design considerations—including selecting mechanical equipment that minimizes shearing of metal containing solids, using a closed-loop sludge wasting and recycling system, employing piping configurations to minimize the potential for solids accumulation and plugging, and laying out the treatment train to take advantage of common unit processes and allow for common access—can promote the treatment system’s ability to comply with the ELGs and simplify its operation and maintenance while promoting system reliability and adaptability.
