ABSTRACT:
A pliable compressible, liquid impervious bag having at least one integral part with a bag hole extending entirely therethrough. The bag includes a structure defining a bag aperture for communicating with the inside of the bag. A plurality of beads is positioned in the bag, and the beads are covalently coupled with a binder. A method for liquid modification comprising installing into a centrifuge bowl the pliable liquid impervious bag having the plurality of beads. A centrifuge cover is secured to the centrifuge bowl, and a liquid having matter to be removed is introduced into the pliable bag. The centrifuge bowl is supn at a predetermined speed in order to mix vigorously the liquid with the beads in the bag in order to expose the beads to a matter within the liquid such that the exposure enables the matter to attach and adsorb to the exterior surface of the beads. The method additionally comprises separating the stripped liquid phase from the pliable bag and the beads including the adsorbed matter that has been removed from the liquid.
