Webinar Papers and Presenters:

IWC 15-58 – Thomas E. Higgins, Ph.D., P.E., CH2M Hill, Jacksonville, FL

Title: Challenges in Flue Gas Desulfurization Physical/Chemical Wastewater Treatment for Mercury and Arsenic

Abstract: Electric utilities are facing a series of regulations that will likely require advanced treatment of flue gas desulfurization (FGD) wastewater.  The proposed Effluent Limitation Guidelines (ELG) of 2013 and water quality based effluent limits (WQBELs) will necessitate treatment of FGD water. The appropriate treatment technologies for meeting these limits will be driven by the pollutants regulated.  This presentation will focus on recent evaluations of physical/chemical treatment, with an emphasis on findings regarding mercury removal.

IWC 15-59 – Frank Sassaman, Evoqua Water Technologies LLC, Warrendale, PA

Title: Treatment of FGD Wastewater in a Pilot Advanced Reactive Iron Media Wastewater Treatement System

Abstract: This paper focuses on the performance associated with the reduction of selenium. Reduction of mercury, arsenic, and numerous other trace heavy metals is also examined as well as the effect of hydraulic retention time, dynamic flow changes, influent chemistry changes, and response to typical real world upsets. Data will be specifically analyzed and discussed in association with meeting the pending ELG guidelines.
