    Abstract: A scrubbing process for high feed concentrations of different materials in liquid streams. The process calls for providing a porous membrane (11) in a cell (10), the mem­brane (11) having pores of sufficient dimension to allow passage of the different materials therethrough; providing a first stream (12) comprising the different materials in a liquid carrier, providing a second stream (13) comprising an affinity adsorbent in a second liquid carrier, wherein the affinity adsorbent has a dimension larger than that of the pores and has a preferred binding capacity for at least one but not all of the different materials; mixing the first and second streams together to form a composite mixture (14) wherein a portion of the different materials become bound to the affinity adsorbent and a portion of the different materials remain essentially unbound to the affinity adsorbent; and passing the composite mixture against a first side of the membrane while passing a liquid carrier (16) for any of the unbound material against a second side of the membrane to produce a first exit stream (19) containing the affinity adsorbent and a high concentration of at least one of the different materials and a second exit stream (18) containing the liquid carrier and a high concentration of at least one of the other different materials.
