Hungerford & Terry, Inc.
About
Founded in 1909 and headquartered in Clayton, New Jersey, Hungerford & Terry is an employee-owned manufacturer of municipal and industrial water treatment systems with over 115 years of continuous operation. The company's filtration line centers on the HFS Series horizontal filter system for multi-MGD potable water treatment, the Plug & Play Greensand Plus system for pre-engineered iron, manganese, arsenic, radium, and hydrogen sulfide removal at 6 gpm per square foot, and self-cleaning underdrain filters in horizontal multi-cell configurations. Their ion exchange division builds custom vessels up to 132 inches in diameter for nitrate removal, color and TOC reduction, and water softening, with a notable installation in Chino, California featuring six 132-inch nitrate removal vessels. Additional treatment offerings include demineralizer systems for boiler feedwater and high-purity applications, condensate polishers for high-temperature power generation duty, forced draft and vacuum degasifiers for CO2 and oxygen stripping (achieving effluent O2 as low as 0.67 mg/L from 8 mg/L influent), reverse osmosis systems, and PFAS/PFOS removal solutions using ion exchange and specialized media. Hungerford & Terry uniquely holds nuclear-grade quality control certifications for government and nuclear power clients. In-house engineering, pilot laboratory testing, system rebuilds, and custom engineered specialized systems round out the service portfolio.
