Further develop and optimize the economic extraction of useful materials from residual “frac” water used in the development of natural gas wells. Hydro Recovery’s process converts the used water into a Hydraulic Stimulation Fluid (HSF™) that can subsequently be reused to extract more natural gas. This process eliminates the need to transport wastewater over long distances. Further, recycling frac water into a reusable product will save millions of gallons of freshwater each year and eliminate discharge of treated water into waterways.
