Abstract | The experimental data show the high-pressure system to be much more effective than the low-pressure system for the removal of all contaminants and natural constituents. The high-pressure system had rejections ranging from 78 to 99 percent, and the low-pressure system from 20 to 85 percent. Rejections varied with the specific contaminants, but the order from best to least was the same for both systems: arsenic V, fluoride, arsenic III, and nitrate. Because of the low rejections, the low-pressure system was able to achieve the EPA maximum contaminant levels when the feed water concentrations were only slightly above them. |
