In December of 2016 Entex’s Webitat submerged fixed film installation at the Superfund site at Woburn, MA started up. Eighteen Webitat units were installed, anchored on a specially built pier in this lagoon. The original objective was to remove ammonia from the system. While the treatment objectives were complex, involving a formula to include temperature and alkalinity, generally we needed to treat to below 1 mg/l of ammonia.

Entex Technologies recently completed an exciting installation of its WavTex Integrated Fixed-Film Activated Sludge (IFAS) system at the Phantom Ranch Wastewater Reclamation Facility (WRF), located at the base of the Grand Canyon. The Phantom Ranch is a popular destination for hikers and mule riders, attracting thousands of visitors each year.

Entex’s WavTex IFAS Installation for Peterborough, Ontario was featured in the Spring 2022 Edition of Influents, the official publication of the Water Environment Association of Ontario (WEAO). Complementing the issue’s theme of Innovative and Alternate Treatment Technologies, the article describes a fixed-film WavTex system as an alternate treatment approach from the plant’s previous IFAS configuration consisting of suspended MBBR media.

Does your wastewater treatment system require energy efficient alternatives for BOD and nutrient removal? If so, Entex’s innovative solar powered WavTexTM module will be a great fit for your system. Featuring our proven EnTextileTM attached growth media, the module utilizes all of the benefits of Entex’s WavTex biological process with none of the operating costs or demands for a local power source.

The 18 MGD wastewater treatment plant in Peterborough, Ontario had problems with media breakage and washout within their MBBR system. Entex replaced the failing MBBR with their WavTex system in the fall of 2021.

In July of 2020, the 0.65 MGD lagoon system in Pax, WV was upgraded with three floating WavTex modules and two floating Octopus aerators to meet a new effluent requirement of <5 mg/L of ammonia.

The wastewater treatment plant in DeQuincy, LA had an aging aeration system providing poor mixing and treatment. Entex replaced this system with 9 floating Octopus modules. The installation was staged to ensure no interruption in operations.

In serving both our municipal and industrial customers, Entex works with a wide variety of systems with different needs, limits, and challenges. One need that all of these systems have in common is air. Whether airflow is distributed through coarse or fine bubble diffusers or through one of our fixed-film media systems, a well

The Blue Cypress Golf & RV Resort needed a new wastewater plant capable of treating 50,000 gpd. Entex, in partnership with Galene Water Treatment, incorporated our patented WavTex system in their FRP packaged plant to meet permit limits of < 15 mg/L of BOD5 and < 6 mg/L of TKN. High seasonal load variations provided additional challenges.

Entex installed a floating WavTex and Octopus system in the Pax, WV wastewater treatment lagoon in late July 2020. Just 2 months after the installation, the plant operator has reported that the floating duckweed had been steadily disappearing, the suspended algae was gone, the green tint in the effluent had gone away, and that he was surprised to be able to see the gravel on the slope of the lagoon floor.
