ABSTRACT:
Water contaminated with sodium, calcium or magnesium salts or chloride, sulfate or carbonate salts is processed to produce a clean water stream and a waste water stream. The clean water stream is analyzed to determine if the sodium content is too high for potable use and, if so, the clean water stream is applied to soil to improve rain catchment for pond sealing.
