Selenium, Chromium and Arsenic Removal Using Zero Valent Iron Media
Zero Valent Iron (ZVI) media effectively neutralize or eliminate specific pollutants, without generating toxic byproducts. The ZVI media reacts with the contaminants and removes them from the contaminated water.
While ZVI has been used for in-situ applications in the form of a permeable reactive barrier (PRB), Envirogen has developed an alternative use of ZVI in an active water treatment system. Our proprietary system can be engineered to address specific contaminants, influent concentrations, and effluent limits for your application. The AMRS relies on Zero Valent Iron technology to deliver high removal efficiencies allowing customers to comply with stringent wastewater discharge permit limits.
Envirogen’s Advanced Metals Removal System (AMRS) can be employed for applications with very low effluent limits for difficult to remove metals such as selenium, chromium and arsenic. It is employed primarily for groundwater and wastewater remediation.
A recent pilot study for treatment of coal ash pond water has demonstrated the effectiveness of the AMRS to reduce selenium levels to single digit parts per billion, even when faced with the more difficult-to-treat species such as selenate.
