## Abstract

A wastewater treatment system includes a blower providing air to an aerator and a low pressure pulsed air mixer. The invention generally relates to a wastewater treatment system and more particularly to a wastewater treatment system to eliminate biological and nutrient contaminants from wastewater.

## Claims

### Claim 1

A wastewater system comprising: a blower providing air to an aerator and a low pressure pulsed air mixer.

### Claim 2 (depends on 1)

The wastewater system of claim 1, the wastewater system including a first stage tank, wherein the aerator is located in the first stage tank.

### Claim 3 (depends on 2)

The wastewater system of claim 2, wherein the first stage tank is a biological oxygen demand zone.

### Claim 4 (depends on 2)

The wastewater system of claim 2, wherein an additional aerator is located in a second stage tank.

### Claim 5 (depends on 4)

The wastewater system of claim 4, wherein the second stage tank is an ammonia reduction zone.

### Claim 6 (depends on 4)

The wastewater system of claim 4, wherein the low pressure pulsed air mixer is located in a third stage tank.

### Claim 7 (depends on 6)

The wastewater system of claim 6, wherein the third stage tank is an anoxic zone.

### Claim 8 (depends on 7)

The wastewater system of claim 7, further including a low pressure pulsed air pump.

### Claim 9 (depends on 1)

The wastewater system of claim 1, wherein the low pressure pulsed air mixer is in one or more of a first stage tank and a second stage tank.

### Claim 10 (depends on 1)

The wastewater system of claim 1, further including a low pressure pulsed air pump.

### Claim 11 (depends on 10)

The wastewater system of claim 10, wherein the low pressure pulsed air pump pumps fluid from a treatment zone or clarifier zone to another zone.

### Claim 12 (depends on 1)

The wastewater system of claim 1 wherein the aerator is located in an oxygen-rich zone.

### Claim 13 (depends on 12)

The wastewater system of claim 12, further including an additional low pressure pulsed air mixer in the oxygen-rich zone.

### Claim 14 (depends on 11)

The wastewater system of claim 11, wherein the low pressure pulsed air pump pumps fluid to an anaerobic zone.

### Claim 15 (depends on 1)

The wastewater system of claim 1, wherein the aerator includes a plurality of air diffusers, wherein at least one of the air diffusers provide air to the lower pressure pulsed air mixer.

### Claim 16 (depends on 11)

The wastewater system of claim 11, wherein the air diffuser providing air to the lower pressure pulsed air mixer is positioned between a support ballast and an open bottom portion of the lower pressure pulsed air mixer.

### Claim 17

A wastewater system comprising: a blower providing air to an aerator; a low pressure pulsed air mixer and a low pressure pulsed air pump.

### Claim 18 (depends on 17)

A wastewater system of claim 17 comprising of moving bed biofilm reactor (MBBR) process, with variable carrier element filling degree from 0-100%.

### Claim 19

A wastewater system of single or multiple treatment zones of suspended, fixed or combined microbial processes, comprising: a blower providing air to an aerator and a low pressure pulsed air mixer.

### Claim 20 (depends on 19)

The wastewater system of claim 19, the wastewater system including a first stage tank, wherein the aerator or low pressure pulsed air mixer, or both aerator and low pressure pulsed air mixer is located in the first stage tank.
