Abstract
A method for the assembly of biofilm support structure modules from individual sheets of biofilm support structure. The apparatus consists of a number of dowel rods protruding from a base. Hollow tubes are placed over the rods. Alignment holes are made in the biofilm support structure sheets such that the sheets may be slid over the tubes. When the required number of biofilm support structure sheets have been stacked in this fashion, caps are attached to the ends of the tubes, holding the biofilm support structure sheets in place. The assembled biofilm support structure modules may then be placed in a wastewater treatment plant. The tubes may also be used as passages for outside air or water, allowing the biofilm support structure sheets to be cleaned while still inside the treatment plant.
