Supplies site-specific activated-carbon, oxidizer, testing, engineering, and support solutions for coal-plant mercury control and water treatment, earning primarily from treatment-media sales alongside patent licenses, equipment, demonstrations, and consulting. Its legacy air business remains tied to coal generation and mercury rules.
Supplies specialty activated-carbon technologies for air and water purification in the United States. Its mature Clean Air / ME2C platform combines SEA® oxidizers with formulated sorbents, plant audits, injection guidance, analysis, and operational support for coal-fired utilities seeking mercury control. Materials sales, patent licenses, demonstrations, consulting, and commissioned equipment form its revenue model.
Extends the same testing-led approach into municipal drinking water, process water, and industrial wastewater through Design Centers, treatment-system engineering, media supply, commissioning, and spent-carbon reactivation. The water platform includes testing across activated-carbon and ion-exchange options rather than a single proprietary medium. Air demand remains tied to coal-plant activity and mercury rules, while water-market timing depends on federal and state PFAS rules.
