Oct. 28, 2014, Grande Prairie, Alta. – A water treatment company has successfully and cost-effectively removed hydrogen sulphide from frac flowback and produced water sources to a non-detect level.


HydroSphere Energy Solutions (Canada) Corp., known as HydroSphere, has completed several on-site sour water treatment jobs reducing hydrogren sulphide (H2S) concentrations of up to 12,000 ppm to 0 ppm (“non detectable”). One of the company’s clients has estimated their net savings are in excess of $100,000 per well, including savings from reusing the treated water in subsequent fracs, said the HydroSphere in a news release.


The mobile treatment process employs a liquid chemical-free combination of sciences that provide a very high rate treatment for bacteria, scale, organics and hydrogen sulphide while producing a fluid that is more compatible with other chemicals being used in the completions process. Unlike traditional scavengers that coat the outer walls of H2S molecules, the Ozonix(R) Advanced Oxidization Process fully oxidizes hydrogen sulphide, creating a safer fluid that can be recycled and reused in the fracturing process, said the company.


“We knew from our research and our pilots that Hydrosphere could treat sour water successfully and economically – so it's great to see the commercial performance outcomes exactly as planned,” said Scott Donahue, chief executive officer of HydroSphere. “Hydrosphere can also reduce the need for harmful chemical additives to the water. And, unlike other water treatment technologies, it's very rapid and leaves no residues.”


Under an exclusive licensing agreement, HydroSphere said its aim is to build a fleet of Ozonix(R) water treatment systems to service the industry’s growing water challenges.
