What Problem Do We Solve?


Selenium removal has become a pressing problem for Power Plants, Mine’s and General Industry Globally. Removing Selenium is unlike many other pollutants in that the different species (Selenium, Selenate, Selenite) & Organo Selenium compounds each require a different technical approach. Removal efficiency is highly dependent on influent quality, quantity, chemical composition, and temperature.  There is no one technological solution that meets all conditions, chemistry and concentrations.

Liberty Hydro offers a simple to use and operate technology focused on Selenium Reduction.  Our ZVI Blue™ product can address all species of selenium and 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 target particularly difficult elements of Selenium, we can achieve among the lowest levels of selenium concentrations required.

Using our patented “Suspended Reagent” approach,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 changeout.

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.
