Abstract
A device for purifying a workstream of contaminants and method of making. One device is made of an inorganic monolithic porous particulate filter and a continuous uninterrupted coating of activated carbon impregnated into the pores of the filter. Preferably the filter has inlet and outlet faces, and a multiplicity of cells separated by porous walls and extending longitudinally and mutually parallel therethrough from inlet to outlet end, a portion of the total number of cells being plugged at the inlet end face, and the remaining portion of the total number of cells being plugged at the outlet end face of the device. Another device can be made entirely of activated carbon having the multicellular structure. A workstream containing contaminants is passed through the device to cause retention of the contaminants. The device can have electrically conducting mechanism for conducting electric current therethrough for removal of the contaminants and regeneration of the device.
