A water recycling project in Texas to convert produced water into freshwater, brine, and hydrocarbon streams has since June been using a Hippo® mobile water treatment plant from Omni Water Solutions equipped with Dow ultrafiltration and reverse osmosis membranes.
The equipment has so far treated more than 245,000 barrels (29,000 m³) of flowback and produced water from the Eagle Ford shale hydraulic fracturing operation to reduce hardness and boron.
The project’s goal is to reduce boron levels from 90 ppm to less than 5 ppm in the fresh water stream, so it is compatible with gel frac formulations and can be reused in subsequent well operations without having to blend in additional fresh water.
