1. A method of forming a biofilm reactor, the method comprising:
forming a fixed film media pod having a mesh structure with openings framed by polymeric material and with no random packing on an interior thereof;
affixing at least one float onto the fixed film media pod;
installing the fixed film media pod into a wastewater treatment tank and into a liquid in an interior of the tank such that the fixed film media pod resides in a generally vertical orientation above a bottom of the tank;
placing an air diffuser into the liquid in the interior of the tank at an exterior of the fixed film media pod;
wrapping the polymeric mesh around an interior or an exterior of a top ring and a bottom ring so as to create a generally tubular structure;
joining ends of a polymeric mesh panel so as to create a teardrop-shaped structure; and
affixing the teardrop-shaped structure into an interior of the generally tubular structure of the fixed film media pod.
