The receptacle comprises a plurality of hollow fibers extending the length of the receptacle and at least one solid absorbent material occupying a space between the plurality of hollow fibers. Each hollow fiber comprises at least one opening and a lumen defined by the walls thereof, allowing the liquid to flow through. The hollow fiber walls have a porosity profile selective to passage of waste materials contained in the liquid from the lumen to the solid absorbent material(s), thereby filtering the liquid.
