摘要： A process (10) for providing water with a lowered salinity and which produces at least one recoverable waste stream containing a useful by-product, includes treating raw water (12) which has an undesirably high concentration of cations, including Ca 2+ and Na + , in a cation exchange stage (14). The cation exchange stage 14 includes at least first and second cation exchangers (18, 20). The first cation exchanger (18) has a selectivity towards di-valent cations and the second cation exchanger (20) is downstream of the first cation exchanger (18). From time to time, the first cation exchanger (18) is regenerated with an acid to produce a first recoverable waste stream (50) which includes a calcium salt, and from time to time, Na + is removed from the second cation exchanger (20) to produce a second recoverable waste stream (58) which includes a sodium compound.
摘要翻译：提供具有降低的盐度的水并且产生含有有用副产物的至少一种可回收废物流的方法（10）包括处理具有不期望的高浓度阳离子的原水（12），包括Ca 2 +阳离子交换阶段（14）。阳离子交换阶段14至少包括第一和第二阳离子交换剂（18,20）。第一阳离子交换剂（18）对二价阳离子具有选择性，第二阳离子交换剂（20）在第一阳离子交换剂（18）的下游。有时，第一阳离子交换器（18）用酸再生以产生包含钙盐的第一可回收废物流（50），并且不时地去除Na + 从第二阳离子交换器（20）产生包含钠化合物的第二可回收废物流（58）。

摘要： The invention comprises water desalination methods and a system for such, which includes treatment of water in cation and anion ion exchange columns, and regenerating the columns after treatment of the water to set them up again for a further treatment cycle, and also providing recoverable by-products during the regeneration of the ion exchange columns instead of waste.
摘要翻译：本发明包括水脱盐方法及其系统，包括处理阳离子和阴离子交换柱中的水，并在处理水后再生塔，再次再次进行处理循环，并且还可通过 - 在离子交换柱再生期间的产物，而不是废物。
