Water. desalination + reuse

PROJECTS August-September 2014 | Desalination & Water Reuse | 29 | PROJECTPROGRESS NEw TExaS dESaliNaTiON PlaNT COuld REuSE fRaCkiNg waTER A new desalination test facility in Loving County, Texas could be deployed in treating water used in hydraulic fracturing – fracking – for shale gas for reuse in the oil industry. The county said the technology used in the plant was, "capable of treating brackish groundwater, produced water, and frack water." The DyVaR technology evaporates the brackish water in cyclone chambers where pure water is condensed and the brine is concentrated for disposal as a solid. The county has finished installing a US$ 3.5 million solar-powered, evaporative desalination unit designated for drinking water production from brackish water. "For produced or frack water, a process like this could produce water for reuse in the oil field," said the plant project engineer, James Busby. The project, located in Mentone, was funded by Loving County and the federal Bureau of Reclamation by way of the WaterSMART innovative water treatment grant programme. There are no seawater desalination plants currently operating in Texas but there are 46 municipal brackish water desalination facilities operating across the state, according to a local news report. Another local report citing state climatologist John Nielsen- Gammon described the Texas drought - currently in its fourth year - as, "among the five worst in the past 500 years...If it continues to be as dry as it is has been, the drought could be the third worst." POiNT liSaS NEaRS ENd Of SixTh ExPaNSiON Desalcott's Point Lisas seawater reverse osmosis is nearing the completion of its sixth expansion since it was commissioned in April 2002. The expansion consists of the addition of a 914 mm intake header, three 483 mm pipelines from the intake to the plant, an upgrade to the flocculation/sedimentation basins, a clearwell pump, one seawater reverse osmosis train, two brackish water reverse osmosis trains, a 915 mm permeate header, a product delivery station and modifications to the chemical feed systems. The next planned expansion is scheduled for June 2015 and will include adding more reverse osmosis capacity along with a Pall microfiltration pretreatment system, following three years of pilot studies. The plant is the largest seawater desalination plant in the western hemisphere according to Desalcott. 2014 DESALINATION AND WATER REUSE INTERNATIONAL CONGRESS WWW.DESAL2014.COM ALADyR through Gecamin is organizing the more important desalination and water reuse event in LATAM Region.
