Random tower packing simply pours the filtration media into the tower. The uneven distribution and orientation of the parts increase the surface area and enhances the transfer of mass between two fluids. The benefits of random packing media only come from narrow towers without ready access. In some instances, random packing material may augment existing material to increase a tower's capacity. The media used for this type of packing have a variety of shapes. The shapes determine the total surface area, uniformity of distribution, wetting area and more. You can use these selection criteria of packings to find the best media for a specific application.
