ABSTRACT:
Undesirable ionic species are removed from water by way of a passive treatment employing apparatus in the form of a porous container which confines a multitude of pieces of sponge containing a chelation polymer. The container, preferably of tubular shape and having a draw-string closure, is emplaced into a region through which water to be treated is caused to flow. The manner of emplacement is such as to prevent by-pass of water around the container. After a suitable time interval, the apparatus is removed and replaced with similar apparatus having fresh sponge.
