<p>A method and apparatus for treating liquid is disclosed utilizing two or more treatment tanks (10, 12) connected in parallel for treating the liquid. The treatment tanks (10, 12) are essentially alike in terms of treatment performance. The tanks (10, 12) each contain a bed of treatment material which may be regenerated. The treatment material in only one of the tanks (10, 12) is regenerated at a time, such that the remaining tank or parallel connected tanks may continue to supply treated liquid.</p> |
