RANDOM PACKING MATERIALS

摘要

A bed for the treatment of fluids comprising a plurality of packing units. Each packing unit has a plurality of fins disposed around an axis lying substantially in the plane of each of the fins. The fins are held in a speed relationship to one another by at least one generally annular reinforcing member between each angularly adjacent pair of fins in a plane substantially perpendicular to the axis. The outward facing edges of the fins are serrated.
