## Abstract

An aeration system for the treatment and purification of liquid is presented. The aeration system includes a decompression chamber extending a length between an inlet end and an outlet end and a motor connected to the decompression chamber. The system includes drive shaft connected to the motor and extending into a hollow interior of the decompression chamber wherein airflow into the hollow interior is restricted through at least one inlet port. An orifice plate is connected to the drive shaft, wherein the orifice plate includes a plurality of apertures. A rotor disk is connected to the drive shaft, wherein the rotor disk includes a plurality of deflecting blades. When the outlet end of the system is positioned in liquid and the driveshaft and rotor disk are rotated micro bubbles are formed in the liquid thereby treating and purifying the liquid.

## Claims

### Claim 1

An aeration system for the treatment and purification of liquid through aeration comprising:
a decompression chamber extending a length between an inlet end and an outlet end;
a motor connected to the decompression chamber;
a drive shaft connected to the motor and extending into a hollow interior of the decompression chamber;
wherein airflow into the hollow interior is restricted through at least one inlet port;
an orifice plate connected to the drive shaft;
wherein the orifice plate includes a plurality of apertures;
a rotor disk connected to the drive shaft;
wherein the rotor disk includes a plurality of deflecting blades;
wherein when the outlet end of the system is positioned in liquid and the driveshaft and rotor disk are rotated micro bubbles are formed thereby treating and purifying the liquid.

### Claim 2 (depends on 1)

The apparatus of claim 1 wherein the motor is submerged in the liquid.

### Claim 3 (depends on 1)

The apparatus of claim 1 wherein the motor is positioned above the decompression chamber.

### Claim 4 (depends on 1)

The apparatus of claim 1 wherein the at least one inlet port is manually or automatically adjustable.

### Claim 5 (depends on 1)

The apparatus of claim 1 wherein at least one of the plurality of deflecting blades extend out from a bottom surface of the rotor disk.

### Claim 6 (depends on 1)

The apparatus of claim 1 wherein at least one of the plurality of deflecting blades are formed of louvers.

### Claim 7 (depends on 1)

The apparatus of claim 1 wherein rotation of the rotor disk creates a vortex in the liquid.

### Claim 8 (depends on 1)

The apparatus of claim 1 wherein rotation of the rotor disk creates a vortex in the liquid pushing micro bubbles outward from the rotor disk.

### Claim 9 (depends on 1)

The apparatus of claim 1 wherein rotating the rotor disk with deflecting blades creates openings in the liquid which draws the air or gas into the liquid through the apertures in the orifice plate.

### Claim 10 (depends on 1)

The apparatus of claim 1 wherein the orifice plate is connected to the driveshaft and rotates with the driveshaft.

### Claim 11 (depends on 1)

The apparatus of claim 1 wherein an opening is positioned in the rotor disk adjacent at least one of the deflecting blades, wherein the opening is positioned rearward of the deflecting blade in the direction of rotation.
