WebMost ion-exchange systems use columns of ion-exchange resin that are operated on a cyclic basis. During the filtration process, water flows through the resin column until the resin is considered exhausted. That happens only when water leaving the column contains more than the maximal desired concentration of the ions being removed. how do you cook pigs liver
