Abstract
Abstract A device for adsorptively removing dissolved organic materials from liquid includes a vertically arranged housing which contains a bed of adsorption media and which has an influent inlet in its base. Two sets of collection launders horizontally extend across the housing, one above the other, and are alternatively used to collect filtrate from the adsorption bed. In the system, two such adsorption devices are connected in series with the connections controlled by valves so that filtrate is discharged from the upper set of launders of the first adsorption device then admitted to the second filtration device, and then discharged from the lower set of launders of the second device. The adsorption devices are further interconnected so that the alternative sets of launders are used when the flow through the system is reversed.
