On-The-Fly System Treats Water for Bacteria, Iron, and Hydrogen Sulfide

The mobile Hydrozonix oxidation system disinfects water and oxidizes iron and sulfides without chemicals that can be incompatible with frac fluids. Used alone or as part of the HzO Trio program, the mobile ozone treatment provides the final polish for water before reuse as a completion fluid.

The mobile oxidation system can handle up to 100 bpm without creating a waste stream. These mobile units are efficient at killing bacteria in the water, and oxidizing iron and sulfides while reducing friction on the fly.

Hydrozonix ozone technology reduces operating, chemical, and disposal costs, and assures that frac fluids will perform as expected without chemical compatibility issues. Our mobile water treatment system has successfully treated millions of barrels of flow back and produced water in five U.S. basins.

High-Volume Treatment without Liquid Chemicals

Other mobile frac water treatment units can have serious limitations. They operate at low treatment rates, require several modules to remove bacteria and other contaminants, rely on chemicals that are not compatible with frac fluids and offer only limited means to monitor water quality or adjust treatment. As part of the Hydrozonix comprehensive water management service, the On-The-Fly system overcomes all these limitations and delivers many other valuable benefits.

The On-The-Fly unit can treat water at 100 bpm, compared to 20 bpm or less for other systems. This high flow rate enables real-time treatment during fracturing and makes the system ideal for quickly treating large water volumes stored in tanks or ponds.

Automated O-Zone

The self-contained On-The-Fly unit thoroughly treats flow back and produced water with an automated approach to oxidation.

The unit generates ozone and mixes it with the water to kill bacteria and oxidize iron and sulfides.
The ozone concentration is automatically as water quality changes.
Dose control via an automated process prevents compatibility problems while ensuring effective treatment—all without the need for an operator.

The Hydrozonix service includes accurate real-time quality measurement of influent and effluent water, which enables rapid adjustment to source water variations and assures consistent frac water quality.

No Liquid Chemicals, No Chemical Incompatibility

Because Hydrozonix does not add liquid chemicals during water treatment, we avoid frac fluid compatibility problems common with other methods. The On-The-Fly process eliminates biocides, iron, and sulfide from the fluid matrix, so treated water has no negative impact on gels or friction reducers, and there is no need to add more of these chemicals after treatment. And because the on-the-fly system uses no liquid chemicals, there are no risks of personnel exposure or environmental spills.

Water treated with the On-The-Fly unit can be pumped at lower pressures and requires less friction reducer than water treated with other methods for important cost savings.
