What Entex Technologies does

Entex Technologies, Inc., founded in 2004 and headquartered at 1340 Environ Way in Chapel Hill, North Carolina, designs, manufactures, and sells advanced biological wastewater treatment and filtration systems for municipal and industrial customers across North America (with select installations in the United Kingdom and Canada). The company's portfolio rests on two technology pillars — proprietary attached-growth EnTextile media used across fixed-film and moving-media systems, and proprietary BioWeb fixed media — implemented in IFAS (Integrated Fixed-film Activated Sludge), SFF (Submerged Fixed-Film), and MBBR process modes. Flagship products include the WavTex moving woven media system, Webitat fixed media system, BioBloc fixed-film modules, BioTex MBBR, and a complementary infrastructure stack of FlowTex disc and drum tertiary filters, Octopus floating aeration, floor-mounted aeration, blower packages, and Solar Powered WavTex for off-grid applications. The company offers an 'unbiased design assessment' across both fixed and moving media, positioning itself as one of the few vendors able to match technology to application rather than a single-process approach.

Commercially, Entex generates revenue primarily through custom-engineered hardware sales (multi-year project contracts, quote-based pricing) of complete treatment systems — packaged plants spanning 10,000 gpd to 3.0 MGD, plus standalone biological modules, aeration, filtration, and blowers — and increasingly through the PEAK Process Optimization Service that adds IoT-enabled remote monitoring, SCADA/lab/field data consolidation, and algorithm-driven optimization to the installed base. The go-to-market is enterprise field sales via North American regional representatives, supplemented by subcontractor relationships with general contractors and consulting engineers on municipal bid projects and direct 'Request a Design' website intake. Customers span municipal government, industrial (chemical, food processing, malting, building products, nuclear power), and decentralized/resort use cases.

The company's claimed scale includes more than 100 installations and 70+ million gallons per day of design capacity, a multi-patent portfolio covering WavTex, BioWeb, Webitat, BioTex, and FlowTex, recognition including the 2014 WEF Innovative Technology of the Year Award and 2014 Frost & Sullivan Product Line Strategy Leadership Award, and an industry analyst 'clear lead' rating from Lux Research (2012). Entex operates with 11–50 employees, is privately held with no disclosed institutional investors, and is led by CEO Wayne Flournoy (formerly President of Kaldnes North America and Director of Water and Wastewater at Brentwood Industries), VP Engineering Jeff Danner, and VP Heidi Rupp.

Core offering

Entex Technologies designs, manufactures, and sells advanced biological wastewater treatment systems for municipal and industrial clients, including moving media (WavTex, BioTex MBBR) and fixed media (Webitat, BioBloc) platforms, aeration systems (Octopus, floor-mounted), tertiary filtration (FlowTex disc and drum filters), blowers, and complete Packaged Plants, supplemented by the PEAK remote process optimization service. The company's core value is delivering nutrient removal and capacity upgrades typically without the need for additional treatment basins.

Product overview

Entex Technologies offers a comprehensive portfolio of advanced wastewater treatment solutions centered on biological treatment technologies. The core product line includes moving media systems (BioTex MBBR, WavTex), fixed media systems (Webitat, BioBloc), and hybrid systems combining both approaches. Supporting infrastructure includes FlowTex tertiary filtration (disc and drum filters), Octopus floating aeration systems, floor-mounted aeration, and blower packages. The PEAK Process Optimization Service adds IoT-enabled remote monitoring and optimization. Packaged Plants integrate these technologies into complete treatment solutions. The company provides both IFAS (Integrated Fixed-film Activated Sludge) and SFF (Submerged Fixed-Film) process modes, offering unbiased design assessments to select optimal technology for each application.
