    摘要： Solid sodium chloride is incorporated into a sodium chloridesaturated brine containing dissolved matter, other than sodium chloride, to be concentrated. The temperature of the system is reduced to within the range from about 0* C. to about -21* C. to form sodium chloride dihydrate. The dihydrate is separated from the aqueous system thereby increasing the concentration of the other dissolved matter relative to the remaining liquid phase. The process is particularly useful for concentrating dilute systems for further treatment or ultimate disposal.

    摘要翻译： 将固体氯化钠加入含氯化钠饱和盐水中，除了氯化钠以外还含有待浓缩的溶解物质。 将体系的温度降低至约0℃至约-21℃的范围，以形成氯化钠二水合物。 二水合物与水性体系分离，从而相对于剩余的液相增加其它溶解物质的浓度。 该方法对于浓缩稀释系统进行进一步处理或最终处置特别有用。
