Purestream Services, a commercial water treatment supplier, has added an installation of its portable induced gas flotation system in Woods County, Okla., to treat produced and flow-back water for an undisclosed oil and gas operation.
The IGF system uses closed-circuit recirculation of treated water and air to remove oil and suspended solids. The mobile system can be moved from site to site for on-demand reuse water needs.
Neil Richardson, Purestream CEO, says this type of well-site system is cost-effective by reducing the hauling of water across long distances for disposal and sourcing. “The IGF technology gives producers on-demand treatment options for their existing operations below disposal and sourcing costs,” he notes.
As hydraulic fracturing continues to boom, produced-water management and its cost-containment become ever more important for oil and gas producers. Treated water gets to be reused for drilling operations. Treating wastewater nearer to the source of production also minimizes the environmental impact of long-distance truck hauling.
A module for produced water purification and recovery and brine concentration, dubbed AVARA (for Accelerated Vapor Recompression), a low-pressure, low-energy mechanical system, is integrated with the induced gas flotation module on a mobile platform. A single IGF cell can process 75 gpm of production water.
According to Purestream, its water treatment technology is already in play at Marcellus Shale as well as at well sites in Arkansas and Wyoming.
