Cheyenne, WY
In August of 2006 the wastewater treatment plant (WWTP) for the Frontier Oil Refinery in Cheyenne, Wyoming received a new effluent discharge limit that required greater ammonia removal than the plant had historically been able to maintain. A combined suspended growth and attached growth nitrification process was determined to be the most cost-effective technology for upgrading the existing bioreactors.
The Colony, TX
In 2005, The Colony needed to expand capacity by 33% from 3.4 million gallons per day (MGD) to 4.5 MGD. Additionally, and nitrify year round to below 3 mg/l. The Colony installed BioWeb and converted from contact stabilization to the IFAS mode. The town saved over $2M in aeration basin construction costs by choosing to modify and augment their existing basins with IFAS media.
Ciales, Puerto Rico
In the fall of 2009, Entex was chosen as the IFAS system supplier for the Ciales Wastewater Treatment Plant and Dos Rios Pump Station. The project consists of a new Pretreatment Facility and a complete retrofit to a BioPortz Moving Media System for nitrification and Carbon Oxidation. Entex’s scope of supply includes media, media retention screens, aerations system, anoxic mixers, and a SCADA system. Construction began in early 2010.
Johnstown, PA
In the fall of 2008, Johnstown, PA installed 32 BioWeb modules in their existing 12 MGD pure oxygen wastewater treatment plant. The plant needed to reduce the clarifier’s solids loading to bring the plant into compliance with their solids effluent limit. The BioWeb system provides additional fixed biomass, allowing the suspended biomass in the system to be reduced, improving the system stability and performance by reducing the clarifier solids loading.
Mt Wolf, PA
AeroMod’s SEQUOX BNR process was selected as the supplier for upgrading the 1.7 MGD Mt. Wolf, PA wastewater treatment. AeroMod asked Entex to participate with them on this project by providing eight Webitat modules to be installed at the end of their system to provide enhanced nitrification and denitrification.
Tabernacle, NJ
The wastewater treatment facility at the Kenneth R. Olson Middle School in Tabernacle, NJ needed to provide enhanced total nitrogen removal. Entex provided the complete system, including media, retention screens and a submersible mixer.
Newark, OH
Entex Technologies increased the treatment capacity and efficiency at the Owens Corning wastewater plant in Newark, Ohio. The upgrade has allowed Owens Corning to vary production levels at the manufacturing site. The innovative Webitat retrofit of Owens Corning’s SBR was the subject of an Industrial Wastewater magazine article in the December 2009/January 2010 issue (Vol. 8, No. 6).
