Abstract: A water treatment system includes: a first vessel having adsorbent materials that form a filtering bed; a second vessel in fluid communication with the first vessel and which includes adsorbent materials that form a filtering bed; an underdrain collection system having ring headers formed below the first and second vessel; a liquid control system in fluid communication with the first vessel, the second vessel, and the underdrain collection system; adsorbent material influent lines; water wash-down lines; raw water lines; and adsorbent material effluent lines, each adsorbent material effluent line having an inlet attached to a bottom of the first or second vessel and an outlet that extends out from the first or second vessel and which is positioned above the ring headers of the underdrain collection system.
