Project Description

Ohio University along with West Virginia University, and American Electric Power, will validate the technical/commercial promise of an advanced multistage process for treatment and reutilization of impaired water as make-up water in fossil fuel-based power plants through small scale testing and prepare the technology for a future pilot scale test effort, if successful. The process is based upon an advanced multi-stage treatment process which utilizes commercial solids filtering and ultra violet light treatment to remediate bacteria, a low-cost natural zeolite to remove naturally occurring radioactive material (NORM) found in oil/gas-based impaired water, electrochemical stripping (E-stripping) and selective sulfation to remove minor constituents, and a breakthrough supercritical water unit design which utilizes internal Joule-based heating to remove major constituents and hydrocarbons.

Project Benefits

It is anticipated that the results obtained from this project will lead to the recovery of 95% of impaired water as a beneficially reusable water product; capability to work with all impaired water chemistries; utilization of E-stripping to selectively remove minor constituents such as Fe2+/Fe3+, Mn2+ Zn2+, Ru2+, and Cu2+; removal of all major impaired water constituents; removal of NORM associated with oil/gas impaired water, and production of non-hazardous bulk solid products for industrial/municipal applications. These could potentially enhance U.S. energy security by: decreasing the intensity of water use in the utility sector, supporting future growth of reliable low-cost fossil-based power generation systems, as well as lowering the costs associated with management of impaired water generated by CO2 storage operations.
