After a SeHAWK® pilot study demonstrated effective treatment of FGD blowdown for selenium, nitrate, arsenic, and mercury removal, a 2800 MW southern power utility chose to install a full-scale SeHAWK® FGD bioreactor at the facility. The system was commissioned in 2019, with Frontier Water Systems personnel providing thorough onsite engineering presence to ensure the successful mechanical, electrical, and operational success of the bioreactor installation. Within two weeks of startup, the SeHAWK® FGD bioreactor demonstrated treatment performance to well below ELG standards.
