✦ Synopsis

Removal of iron from tap water at pH 6.0-7.3 was performed with an ion-exchange resin (Lewatit TP-207) with a chelating iminodiacetic acid group. More than 90% of the iron was removed by passing the water through the resin at a flow rate of 200 bed volumes per hour. The capacity of the resin for divalent iron was 25-30 g/l resin. The regeneration of the resin was carried out with 2 N HCl.
