Abstract

В изобретении предложены устройства и способы умягчения воды, а в частности устройство и способ умягчения воды без добавления ионов в поток сточных вод. Устройство, главным образом, включает в себя по меньшей мере один фильтрующий элемент нанофильтрации, позволяющий принимать входящий поток жесткой воды, выпускать выходящий поток проникающей воды, содержащий часть входящего потока, и выпускать выходящий поток не проникающей воды, содержащий остаток входящего потока. Фильтрующий элемент нанофильтрации обычно имеет средний размер пор, который, главным образом, позволяет проходить воде и однозарядным ионам, но, главным образом, не позволяет проходить двухзарядным ионам.Отчет о международном поиске был опубликован 2003.04.24.
