What Envirogen Technologies does

Envirogen Technologies, Inc. is a privately held US-incorporated water and wastewater treatment company founded in October 2009 (though it markets over 30 years of combined operating experience through its predecessor heritage at Calgon Carbon, US Filter, and Veolia Water North America). The company designs, builds, and operates custom treatment systems for industrial, municipal, military, mining, power generation, and healthcare customers across North America, the UK, and continental Europe. Headquartered in Kingwood, Texas with regional offices in Alfreton (UK) and Zaandam (Netherlands), Envirogen runs an installed base of 125+ managed water systems, 40-200+ fluidized bed reactor (FBR) installations, and 120+ air emissions systems.

The core technology portfolio centers on the proprietary Fluidized Bed Reactor (FBR) — covered by 9 US patents and used to biologically destroy perchlorate, nitrate, selenium, and 1,4-dioxane at >99% efficiency — alongside Membrane Bioreactors (MBR), PureSep hollow fiber UF/NF membranes, Reverse Osmosis and Electrodeionization (Eco MultiPro RO-EDI), FerroLock Zero Valent Iron (AMRS) for metals removal, and ion exchange systems (SimPACK, MinX). Trademarked product families include EndoTherm (healthcare water purification, AAMI ST108 compliant), EcoRange, PureSep, FerroLock, SimPACK, and MinX. Operations span biological, membrane, adsorption, ion exchange, and physical-chemical process technologies.

Envirogen makes money through a mix of capital equipment sales (Design/Build, Design/Build/Operate, Design/Build/Own/Operate contracts), long-term managed O&M services backed by performance guarantees (Lifecycle Cost Assurance Program), recurring service contracts and consumables (resins, membranes, ZVI media), and ion exchange service models (PEDI, MODI, WWSDI). Pricing is custom and project-specific with no published rate cards; the sales motion is consultative and engineering-led, anchored by bench/pilot treatability studies and free site assessments, targeting enterprise and government buyers through direct field sales augmented by engineering consultant referrals.

Revenue model

1. Water and Wastewater Treatment Systems (Design/Build): Custom-designed and built treatment systems for water, wastewater, and groundwater remediation. Includes FBR, MBR, RO, UF/NF, ZVI, and IX systems. Revenue from capital equipment design, fabrication, and installation. Delivered under Design/Build (DB), Design/Build/Operate (DBO), or Design/Build/Own/Operate (DBOO) contracts.
2. Operations & Maintenance (O&M) Services: Long-term O&M contracts providing full-time staffing, routine service, licensed operator services, emergency response, and performance guarantees for water treatment systems. Lifecycle Cost Assurance Program offers guaranteed outcomes over the asset's lifetime. Near 100% system run time delivered across 125+ managed systems.
3. Ion Exchange Resin Services (PEDI, MODI, WWSDI): Portable Exchange Deionization (PEDI), Mobile Deionization (MODI), Wastewater Service Deionization (WWSDI), and off-site resin regeneration services. Operates from Memphis, Tennessee facility. Tank exchange programs and trailer-mounted emergency deployment.
4. Lifecycle Cost / Pay-for-Performance Contracts: Long-term guaranteed performance contracts structured around total cost of ownership (TOTEX/lifecycle cost) rather than CAPEX. Performance guarantees cover asset life, treatment outcomes, and operating costs, reducing customer risk and ensuring regulatory compliance.
5. Service Contracts and Consumables: Preventative maintenance contracts, emergency support services, consumables (resins, membranes, ZVI media), and spare parts supply for installed base of 125+ systems and 40+ FBR installations.
