ABSTRACT:
Liquid is purified by passing it through a bed containing disc-shaped buoyant media beads having grooved surfaces. Such beads are formed from a polymeric pellets. The pellets are passed through a scarifier to roughen their surfaces. Pellets are also passed through a rolling mill which grooves the pellets and compresses them into disc-like shapes.
