Abstract
A unique filtration device ( ) which removes metal ions from a contaminated aqueous stream through the use of partially hollow wicking fibers ( ) impregnated with a selected liquid ( ) which can capture the metal ions in the aqueous stream. The wicking fibers ( ) are formed into a filter element ( ) which extends from a chamber ( ) through which the aqueous stream is directed into a chamber ( ) wherein the unwanted metal ions are removed from the extracting liquid ( ). The wicking fibers ( ) include internal longitudinal cavities ( ) each with a relatively small longitudinal extending opening ( ). The wicking fibers ( ) are filled with the selected liquid extraction ( ) which remains within the fiber through capillary action by which capillary action the individual wicking fibers ( ) rapidly draw the selected liquid,( ) with which they comes into contact, through the internal cavities ( ). The liquid extrant ( ) remains within the wicking fiber cavities ( ) and generally does not enter the space between the wicking fibers ( ) yet through the longitudinal openings ( ) the liquid ( ) is in full communication with the metals contaminated aqueous stream flowing through the filter ( ) and past the individual fibers ( ).
