Abstract: A method of removing chromium from water using a weak base anion exchange resin at a pH above about 5 includes the step of periodically reducing a flow of the water through the ion exchange resin for a rest period, such that a secondary mechanism of chromium removal predominates, wherein chromium ions are removed from the weak base anion exchange groups and precipitated inside the ion exchange resin. In an alternative embodiment, rather than resting, the ion exchange resin is periodically conditioned with an acid so as to enhance the secondary mechanism.
