Selenium removal has become a pressing problem for power plants, mines and many other industries globally. Selenium, and its various components is unlike many other pollutants in that it requires a unique technical approach for removal. Species such as selenate are difficult to remove from waste water and have traditionally required complex systems that are expensive to install and operate.

A simpler and less expensive approach utilizes zero valent iron (ZVI) which is a strong reducing agent and one of the few that can reduce selenate ions to inert, elemental selenium, while also tackling hard to address organo-selenium compounds.

Liberty Hydro Inc. offers a simple to use and operate ZVI technology focused on selenium reduction.  Our ZVI Blue™ product can address all species of selenium, including organo-selenium compounds, over a wide variety of operating parameters.  Whether as a stand-alone solution for selenium removal, or as a polishing step to achieve particularly difficult target concentrations of selenium, we can achieve the lowest levels of selenium concentrations required.

Using our patented Suspended Bed technology, ZVI Blue™ ensures very high contact rates between the process water and the reducing surface. Our modular design can scale up or down for the process requirements and our cuboid media has been designed for maximum efficiency in operation and ease of change-out.

Pilot tests in mine and power plant applications have proven that ZVI Blue™ will achieve among the highest rates of reduction of selenium, selenate, selenite and organo-selenium compounds in the industry today.
