摘要：

The newly conceived and recently reported closed circuit desalination (CCD) Technology has been successfully demonstrated for nitrate decontamination. The application of the brackish water reverse osmosis-CCD(BWRO-CCD) Technology to feed sources of 98, 144 and 197ppm NO3 gave the respective amounts of 19, 27 and 45ppm NO3 in permeates from said sources obtained with 90% recovery at 20 degrees C. The illustrated NO3 rejection finding of the BWRO-CCD Technology, considered in the context of high flux, high recovery, low energy demand and reduced fouling factors may suggest the plausibility of this cost-effective approach for nitrate decontamination of drinking water worldwide.
