Abstract
A water treatment system may generally comprise a generally cylindrical halogenated resin bed comprising an empty bed contact time greater than 1 second, an aspect ratio less than 0.8, and a fluid velocity less than 0.5 cm/s, wherein the aspect ratio is the ratio of the length of the halogenated resin bed to the diameter of the halogenated resin bed; and wherein the fluid velocity is the quotient of the volumetric flow rate of the water treatment system and the cross-sectional area of the halogenated resin bed; and wherein the halogenated resin bed improves the removal of contaminates relative to a corresponding water treatment system having an aspect ratio greater than 0.8.
