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.
