News Release Envirogen October 14, 2013Envirogen Announces Start-Up of Large Fluidized Bed Reactor System for Perchlorate Remediation at Nevada Industrial Site Proven, “green” biological treatment technology answers need for treatment of perchlorate-laden groundwater in Henderson, Nevada
Envirogen Technologies, Inc. (Envirogen) announced the successful start-up of a large-scale fluidized bed bioreactor (FBR) system for American Pacific Corporation (AMPAC), to achieve the biodegradation of perchlorate and other constituents from groundwater in the area of a former manufacturing facility in Henderson, Nevada. The 1.2 million gallon per day (MGD) capacity system replaces a smaller biological system that had been in service since 2006, and utilizes Envirogen’s patented FBR technology in a custom configuration to reduce influent concentrations of perchlorate of up to 500 ppm to non-detectable levels prior to surface discharge.
According to Robert Stark, South Region Vice President for Envirogen, the AMPAC installation underscores the rising prominence of FBR technology, both for perchlorate remediation and as a sustainable, cost-effective tool for a wide range of groundwater treatment challenges. “This site presented us with a high-load scenario coupled with the need for trouble-free performance and a low operational burden,” Stark explained. “With this FBR installation, we were able to meet AMPAC’s target treatment goals for perchlorate as well as chlorate and nitrate, while fine-tuning the equipment to provide them with the lowest-cost performance possible. Today, we are pushing FBR technology to meet new challenges for treatment efficiency and cost- effectiveness. Its versatility in handling multiple constituents and varying flow characteristics also points to its potential to treat other contaminants, such as selenium, hexavalent chromium or chlorinated solvents. As sustainability becomes an important element in treatment technology selection, we feel strongly that the use of the FBR in groundwater remediation applications will grow,” he continued.
