Abstract
A beam is pivotally supported at a fixed pivot support, the beam movable in cyclic tilting motion such that ends of the beam move vertically in mutually opposing directions. The ends of the beam are pivotally engaged with vertical arms extending downwardly. The arms terminate with mixing plates immersed within the fluid so that the mixing plates cause fluid mixing as the tilts. A fixed film biomass is engaged with the surfaces of the plates for improved bio-processing within the tanks.
Claims11
An apparatus for mixing a fluid within a tank, the apparatus comprising:
- a beam pivotally supported at a fixed pivot support, the beam movable in cyclic tilting motion such that ends of the beam move vertically in mutually opposing directions;
- the ends of the beam pivotally engaging vertical arms depending downwardly therefrom;
- each of the arms downwardly terminating with at least one mixing plate engaged therewith;
- the mixing plates immersed within the fluid within the tank so that the mixing plates cause fluid mixing as the beam moves in the tilting motion;
- a means for causing the beam to execute cyclic tilting motion;
- and a fixed film biomass engaging the at least one plate for biologically processing the fluid in the tank.

A method for mixing a fluid within a tank, the method comprising the steps of:
- supporting a beam at a balance point on the beam;
- moving the beam in tilting motion about the balance point such that ends of the beam move vertically in mutually opposing directions;
- pivotally engaging the ends of the beam with vertical arms depending downwardly therefrom;
- terminating each of the arms downwardly with at least one mixing plate;
- positioning the mixing plates for being immersed within the fluid in the tank so that the mixing plates cause fluid mixing as the beam moves in the tilting motion;
- engaging a means for cyclically unbalancing the beam to cause the tilting motion;
- and engaging a fixed film biomass on the surfaces of the plates for improved bio-processing of the fluid.
