Cost-Effective, Membrane-Free Desalination and Brine Collection Service for Operators Looking for the Highest-Quality Fresh Water and Saturated Brine
Transform the most difficult water makeup into the highest quality fresh water with Gradiant Energy Services’ (GES) desalination technology. Developed at the Massachusetts Institute of Technology (MIT), our process desalinates oilfield wastewaters to produce extremely fresh water (less than 500 ppm & even lower in many cases) and a highly concentrated brine solution that can be utilized for drilling, work-overs and completions.
How our solution works
Our technology is a membrane-free desalination process that uses air as a carrier gas to extract water vapor from produced water, leaving behind contaminants. This is the same principal as clouds forming over an ocean. The purified water is recovered in a subsequent dehumidification process that utilizes GES’ unique bubble-column heat exchanger, which is similar to clouds releasing rain over land. Our desalination process uses less than half the energy of competing Multi-stage Mechanical Vapor Recompression (MVR) technology commonly used for fresh water recovery from produced water.
