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.
Claims22
A wastewater treatment apparatus comprising:
- a tank having an access opening thereon, said tank having an inlet adapted to allow wastewater to enter an interior of said tank, said tank having an outlet adapted to allow an effluent to exit said tank;
- at least one fixed film media pod positioned in the interior of said tank, said at least one fixed film media pod being formed of a polymeric material, said at least one fixed film media pod having openings framed by the polymeric material;
- a diffuser positioned in the interior of said tank, said diffuser adapted to aerate liquid in the interior of said tank;
- and
- an air pump connected to said diffuser.
A method of forming a biofilm reactor, the method comprising:
- forming a fixed film media pod having a polymeric mesh structure with openings framed by polymeric material;
- 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;
- and
- connecting the air diffuser to an air pump.
A fixed film media pod for treating wastewater, the fixed film media pod comprising:
- a generally tubular structure of a polymeric mesh material, the polymeric mesh material having openings framed by polymeric material;
- a top ring surrounded by or surrounding the polymeric mesh material;
- a bottom ring surrounded by or surrounding the polymeric mesh material;
- and
- at least one float affixed to the generally tubular structure adjacent to the top ring.
