A recent innovative development in the ,removal, of organic species from ,flowback, waters is the potential to use an advanced oxidation process in a batch-wise treatment mode. One unit supplied by Ozonix uses a combination of injection of in-situ generated ozone, hydrodynamic and acoustic cavitation plus electrochemical oxidation to produce the very reactive hydroxyl radicals in the reaction chamber.

The study recounts that at 99% TSS ,removal,, the produced water was success- fully blended into a crosslinked-gel-based frac ,fluid, suitable for hydraulic ,fracturing,. Suspended solids come in various shapes and sizes; removing the visible range of solids, the ones that contribute to turbidity, is insufficient when it comes to frac ,fluid, mixology.

Flowback, water. After a ,fracturing, treatment on a gas well, the pumping pressure is relieved and ,fracturing fluid,, mixed with water from the rock formation, begins to ,flow back, through the well casing to the wellhead. In treatment-and-reuse scenarios, this is the water that will serve as the basis for ,fracturing fluid, for the next job.
