Geosyntec Staff to Attend and Contribute to the 2022 International Water Conference

Geosyntec staff will attend, present and host a booth at the 2022 International Water Conference (IWC2022) at the Hilton in the Walt Disney World Resort in Orlando, Florida, November 6 through 10, 2022.

Kevin Dufresne, P.Eng. (Ontario) will present "Barium Chemistry to Treat Sulfate – But What About Selenium?"  during the technical session titled "Trace Metals – Lithium, Rare Earths and Selenium" which takes place from 8 a.m. to 12 p.m. EST on November 8, 2022. The paper Kevin will present was coauthored by Geosyntec's Mehmet Iscimen, P.E., CPESC (Georgia), Hariprasad Parthasarathy, Ph.D, P.E. (Illinois), and Andrew Holmes, Ph.D., P.Eng (Ontario) as well as Alicia Herrin of Southern Company.

In addition, Phil Benson, P.E., PMP (Washington, D.C.), will discuss the presentation "Carbon Capture: A Water Overview." Geosyntec will also host Booth #111 at the conference.

Other Geosyntec attendees include Shira Colsky, P.E. (Georgia), Mike Hayes, P.E. (Pennsylvania), Hari Parthasarathy, and Kevin Warner, P.E. (Florida).

The International Water Conference (IWC) presents timely, relevant science and continuing education for professionals and students and showcases new technologies and products in the industry. The organization is further dedicated to encouraging the next generation of water related engineers through hands-on courses, practical continuing education, and professional networking.

The event is hosted by the Engineers' Society of Western Pennsylvania, an organization that advances the professions of engineering, architecture, and applied sciences through technical activities, public service participation and social organizations.

Presentation Summary

Title: Barium Chemistry to Treat Sulfate – But What About Selenium?
Presenter: Kevin Dufresne, P.Eng.
Authors: Kevin Dufresne (Geosyntec), Alicia Herrin (Southern Company), Mehmet Iscimen, (Geosyntec), Hariprasad Parthasarathy, (Geosyntec) Andrew Holmes (Geosyntec)
Description: This paper discusses a study using barium chemistry to remove sulfate ions from an industrial wastewater stream and assess its impact on selenium removal. The study demonstrated that for wastewaters rich in calcium and bicarbonate ions, barium hydroxide can be used to simultaneously precipitate barium sulfate and calcium carbonate, while also removing up to 94% of the selenium.
