After several SeHAWK® pilot studies showed successful treatment of FGD blowdown for selenium, nitrate, arsenic, and mercury removal, a southern power utility chose to install a demonstration scale SeHAWK® FGD bioreactor at one of their plants in the South Eastern US. The installation was completed in 2016, demonstrating FGD metals compliance below ELG limits. The system was restarted in October 2019 and continues to operate as a demonstration and R&D unit for the client.
