Abstract
A wastewater treatment apparatus has a tank having an access opening therein, 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 mesh material and has openings framed by the mesh material. At least one weight is affixed to the fixed film media pod adjacent to a bottom thereof so as to maintain a vertical orientation of the fixed film media pod in the tank. The diffuser can be affixed to the fixed film media pod so as to aerate liquid in the interior of the tank.

A wastewater treatment apparatus comprising:
- a tank having an access opening therein, 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 having openings framed by a material, said at least one fixed film media pod having at least one weight adjacent to a bottom thereof, the at least one weight adapted to maintain a generally vertical orientation of said at least one fixed film media pod in said tank;
- a diffuser positioned in the interior of said tank at an exterior and at a side of said at least one fixed film media pod, said diffuser adapted to aerate liquid in the interior of adjacent tank;
- an air pump connected to said diffuser so as to pass air into and through said diffuser;
- a weighted member connected to said diffuser, said weighted member adapted to maintain said at least one fixed film media pod and said diffuser in a generally vertical orientation, said weighted member comprising:
- a pipe affixed to a bottom of said diffuser, said diffuser having a threaded portion at a bottom thereof, said pipe having a coupling threadedly secured to the threaded portion;
- and
- a plurality of weighted elements received in said pipe, said pipe being capped at an end opposite the coupling.
A fixed film media pod for aerating wastewater in a tank, the fixed film media pod comprising:
- a generally tubular structure of a mesh material, the mesh material having openings framed by the mesh material;
- a top ring surrounded by or surrounding the mesh material;
- a bottom ring surrounded by or surrounding the mesh material;
- at least one float affixed to said generally tubular structure adjacent to said top ring;
- a diffuser affixed to an exterior of and to a side of said generally tubular structure, said diffuser adapted to aerate the wastewater in the tank;
- an air pump connected to said diffuser so as to pass air into and through said diffuser;
- and
- a weighted member fastened below said diffuser or connected to said diffuser, said weighted member adapted to maintain said generally tubular structure and said diffuser in a generally vertical orientation, said weighted member comprising:
- a pipe affixed to a bottom of said diffuser, said diffuser having a threaded portion at a bottom thereof, said pipe having a coupling threadedly secured to the threaded portion;
- and
- a plurality of weighted elements received in said pipe, said pipe being capped at an end opposite the coupling.
