摘要： Cations that can precipitate from an aqueous composition to produce scaling are sequestered by adding a multi-dentate ligand to the aqueous composition. The multi-dentate ligand bonds with the cation to form a non-scaling ionic complex; and the aqueous solution with the ionic complex is used in a process that produces substantially pure water from the aqueous composition, where the cation, absent formation of the ionic complex, is subject to scaling. The pH of the aqueous composition (or a brine including components of the aqueous composition) is then reduced to release the cation from the multi-dentate ligand; and the multi-dentate ligand, after the cation is released, is then reused in a predominantly closed loop.

摘要翻译： 可以通过向水性组合物中加入多齿配体将螯合物从水性组合物沉淀以产生结垢。 多齿配体与阳离子结合形成非结垢离子络合物; 并且具有离子络合物的水溶液用于从水性组合物产生基本上纯的水的方法，其中离子络合物的形成不存在结垢的阳离子。 然后还原水性组合物（或包含含水组合物的组分的盐水）的pH以从多齿配体释放阳离子; 并且在释放阳离子之后的多齿配体然后在主要闭合的环路中重新使用。
