Abstract
A wastewater treatment apparatus has a tank with an access opening, at least one fixed film media pod positioned in the interior of the tank, a diffuser positioned in the interior of the tank, and an air pump connected to the diffuser. The fixed film media pod is formed of a polymeric material and has openings framed by the polymeric material. The diffuser is adapted to aerate liquid in the interior of the tank. The media pod has a tubular structure extending vertically in the interior of the tank and positioned above the bottom of the tank. Floats are attached to the top of the media pod so as to suspend the media pod in the liquid in the tank.
Claims5
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.
