ion exchanger
A permanent insoluble material (usually a synthetic resin) which contains ions that will exchange reversibly with other ions in a surrounding solution. Both cation and anion exchangers are used in water conditioning. The volume of an ion exchanger is measured in cubic liters of exchanger after the exchanger bed has been backwashed and drained, and has settled into place. (Source: WQA)
