A system and method for extracting liquid and/or solids from interstices of a porous matrix is disclosed. The porous matrix has two exposed ends, one of which is exposed to a first pressure and at an upstream end and another one of which is exposed to a second pressure and at a downstream end. The method includes first providing a pressure differential between the first pressure and the second pressure, wherein the first pressure is higher than the second pressure. This is then followed by providing foam on the upstream end, where the pressure differential is configured to cause foam movement through the interstices of the porous matrix to extract the liquid and/or solids through the downstream end. |
