Fracking Clean-up with Ozone

Hydraulic fracturing or fracking is a technique in which rock is fractured by a pressurized liquid made of water, sand, and chemicals (90 percent water, 9.5 percent proppants,   and 0.5 percent chemicals usually). This high pressure liquid is injected into a well to create cracks in the deep-rock formations. Proppants are sand and ceramic mixture which keep the cracks open, so when the hydraulic pressure is removed natural gas, petroleum, and brine will flow more freely [1].

How Fracking WorksDuring each hydraulic fracking 1-8 million gallon water is used. 400 gal chemical is used per fracking. These chemicals include 600 chemicals which some of them are toxic or carcinogen. If the water is not treated it will cause surface, soil and ground water contamination [2].

Air quality also can be degraded during fracking as Volatile Organic Compound (VOCs) like benzene can penetrated in Air.

Ozone as a strong oxidant can be used for water reuse and treatment in fracking process. Ozone is powerful in removing VOCs and breaking down the most of dangerous chemicals. So it is anticipated ozone treatment will increase in fracking processes.  You can check out our Ozone Remediation Trailers & Cabinets at our website.

Using Ozone to Clean Up Fracking

Ecosphere’s new technology reduces the use of chemicals and helps natural-gas companies recycle water.

Ecosphere’s process replaces the biocides and descaling agents typically used in fracking water with an ozone-based treatment. Ozone itself isn’t benign, but Ecosphere produces it on site, so it doesn’t have to be transported, which reduces the chance of spills, the fuel needed for transport, and the wear and tear on roads—a major problem for communities with large fracking operations. The process lets well operators recycle water, reducing the total amount consumed and the amount of waste material that needs to be disposed of.

The use of ozone to treat water isn’t new, but it hasn’t been used much in part because it’s expensive. Ecosphere has found ways to reduce the amount of ozone needed by 90 percent. It uses a combination of approaches. First it flows water through proprietary structures that cause tiny bubbles to form and collapse—which is called cavitation. It also uses ultrasound to create more cavitation. In both cases, this breaks up biological contaminants in the water, making the ozone more effective, and creates free radicals that themselves help disinfect the water. The final step is to run an electrical current through the water, which causes some of the salts in the water to precipitate, reducing scaling. The process is cheaper than some other alternatives, such as UV treatment and desalination, the company says.

Cleared up: Ecosphere CEO Robbie Cathey holds up a jar full of dark untreated water, and cloudy water that’s been treated with his company’s technology. The treated water isn’t safe to drink, but it’s good enough for fracking.
