(NASDAQ: FTEK), a technology company providing advanced engineering solutions for the optimization of combustion systems, emissions control, and water treatment in utility and industrial applications, announced today the appointment of William (Bill) Decker as Vice President Water and Wastewater Treatment Technologies, effective March 15, 2023. In this newly created position, Decker will lead the growth and development of Fuel Tech’s Dissolved Gas Infusion (DGITM) technology, including business development, sales and marketing, and new product development and commercialization.

Decker brings to Fuel Tech more than 30 years of engineering, operational, and financial experience serving industrial and municipal water and wastewater clients across the United States and around the world. He joins Fuel Tech from Aqua-Aerobic Systems, a global leader in the design, application, and manufacture of water and wastewater treatment equipment and systems, where he served as Vice President & General Manager Equipment Service Group since 2012. Prior to that, Decker was President of Aquionics, a supplier of UltraViolet (UV) disinfection systems, and he also held positions of increasing responsibility at Ashbrook Simon-Hartley, a global provider of water and wastewater treatment services.

Decker was selected five times by multiple U.S. Secretaries of Commerce to serve on the Environmental Technologies Trade Advisory Committee (ETTAC), including twice as Chairman. ETTAC makes recommendations to the Secretary of Commerce on issues that affect export competitiveness of U.S. environmental technologies.

In November 2022, Decker was elected Chairman of The Water and Wastewater Equipment Manufacturers Association (WWEMA), a Washington D.C.-based non-profit trade association representing water and wastewater technology and service providers since 1908. WWEMA works closely with Congress and other regulatory agencies, monitors legislative actions, testifies before Congressional committees, and advocates for funding to meet environmental goals.

Decker earned his BSCE, Civil Engineering from the United States Air Force Academy and served as a USAF Civil Engineering Officer for 6 years following his graduation. He rose to the rank of Captain prior to his honorable discharge. Decker is currently pursuing a M.S. degree in Occupational Safety and Health.
