The characteristics of HSRO® technology are introduced.Combined with the desulfurization wastewater zero discharge phase I project in a thermal power plant in Inner Mongolia,China,the membrane concentration section of the process has been successfully designed and applied with HSRO device.The device runs stably and reliably with an overall recovery rate higher than 90％.The final water produced by reverse osmosis can be directly reused as production water.This technology has been successfully verified in the field of desulfurization wastewater,and also provides a reference for the process selection in the field of high salinity mine water and concentrated brine in the coal chemical industry.
