Entex Technologies Inc
About
Entex Technologies, Inc. is a Chapel Hill, North Carolina-based manufacturer of advanced biological wastewater treatment systems, holding U.S. patents on its core technologies. The company has deployed its systems across more than 100 installations with a combined design capacity exceeding 70 million gallons per day, serving municipal and industrial clients seeking nutrient removal, capacity upgrades, and effluent reuse. Entex's flagship platform is the Webitat, a versatile biological treatment module designed as a retrofit for wastewater lagoons that incorporates both moving and fixed media to increase biomass concentration without additional tank volume. The WavTex system uses patent-pending EnTextile woven media sheets that move independently within aeration basins, enabling simultaneous nitrification and denitrification within a single tank while eliminating the need for media retention screens. The Octopus is a surface-maintainable floating aeration system with eight stainless-steel legs and up to 32 fine-bubble diffusers per unit, powered by shore-based blowers with no submerged motors, achieving oxygen transfer at roughly half the energy cost of high-speed surface aerators. Entex also offers BioBloc biological treatment modules, tertiary disc filtration for reuse-quality effluent, PEAK Process Optimization services, and packaged treatment plants for turnkey installations. All products are available as rental units for pilot testing.
Key Products
Flexible biological treatment platform using moving and fixed media for retrofitting wastewater lagoons, providing enhanced nutrient removal and increased capacity without new tank construction.
Fixed-film biological treatment system that doubles biomass concentration, requires no new tanks, eliminates the need for screens, and is suitable for upgrading existing activated sludge or lagoon systems.
Flexible aeration system for optimizing dissolved oxygen delivery in biological wastewater treatment processes, supporting both nitrification and BOD removal.
Biological treatment module available as a rental unit for pilot testing or temporary treatment capacity expansion.
Disc filtration system for producing reuse-quality effluent by removing fine suspended solids from secondary or tertiary wastewater treatment effluent.
Consulting and process optimization service that fine-tunes biological treatment plant performance for improved nutrient removal, energy efficiency, and capacity utilization.
Turnkey, factory-built wastewater treatment plant packages incorporating Entex biological and filtration technologies for rapid deployment.
Integrated Fixed-Film Activated Sludge systems combining attached-growth and suspended biomass for enhanced nitrogen and phosphorus removal in cold-weather and capacity-limited plants.
