U.S. Water Secures Approval for New Patent

U.S. Water announces that on May 21, 2019, the Minnesota based company has been granted a new U.S. patent (10,294,126) entitled “Water Treatment Method & System.” 

The technology is a unique process that converts hexavalent chromium, a hazardous material, into a non-hazardous trivalent chromium. The trivalent chromium is then removed using a specialized chelating resin which can then be disposed as a non-hazardous waste. 

U.S. Water began development of this process in response to California adopting a new Maximum Contaminant Level (MCL) for hexavalent chromium in 2014 MCLs are standards that are set by the EPA for drinking water quality.  As part of the development process, multiple pilots were successfully completed, validating the effectiveness of the technology.
