De Nora Water Technologies has completed delivering eight ClorTec mobile disinfection systems to treat frack water at different sites in the Permian Basin, located in western Texas and southeastern New Mexico.

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 Co., 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% 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,” De Nora Water Technologies Texas Managing Director Bryan Brownlie said.

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. The unique design of the ClorTec DN electrode/cell rapidly and effectively removes hydrogen, the only by-product generated by the system.
