De Noa, a designer of sustainable water disinfection and oxidation, filtration, and electrochlorination solutions, has completed delivery of eight ClorTec mobile disinfection systems to treat frack water at different sites in the Permian Basin. As part of the hydraulic fracturing process to release onshore oil and natural gas from shale, water must be disinfected shortly before going downhole to prevent growth of anaerobic, iron-consuming bacteria and other microorganisms.
De Nora worked in conjunction with its partner, Neptune Solutions Company to provide fully equipped disinfection trailers, each with a ClorTec CT-DN on-site hypochlorite system, tanks, dosing pumps, analyzers, HVAC, and a small lab. Each containerized system has the capacity to generate up to 1,500 pounds per day of a 0.8 percent sodium hypochlorite disinfection solution, a chlorine equivalent, using three common consumables: salt, water, and electricity. This is sufficient to treat upwards of 235,000 barrels of frack water per day, per unit.
“We are thrilled to be providing the oil and gas industry with reliable, cost-effective disinfection for their fracking operations in a complete packaged solution,” said Bryan Brownlie, managing director, De Nora Water Technologies Texas, LLC,. “Working together with Neptune Solutions Company, our end users are getting an exceptional, trouble-free product and outstanding personal service. These trailers are disinfecting very effectively with essentially zero bacteriological activity, for months after the frack fluids are pumped.”
De Nora’s initial collaborations with Neptune Solutions Company include a produced water recycling center, which currently treats upwards of 500,000 barrels of produced water per month—which has immediately been used in well completions—and has been in operation since last year.
Generating disinfectant on-site produces a less hazardous hypochlorite solution than bulk hypochlorite and eliminates the need to transport hazardous materials. Additionally, on-site provides protection against chemical price fluctuations and avoids costly chemical containment systems and risk management planning.
