Air Jammer™ Aerator
| The Air Jammer™
aerator is a unique device for injecting atmospheric oxygen into wastewater. The Air
Jammer™ utilizes micron-size bubble diffusion along with hydraulic shear within a
pressurized aeration chamber to produce a well mixed oxygenated and conditioned liquid.
Wastewater, the primary target, is pumped through the Air Jammer's™ high velocity
nozzle at a hydraulic pressure of 20 psi. The resulting implosion and dramatic expansion
thereafter shears the waste stream's organic solids to macroscopic size and releases the
embedded grease and gas bubbles trapped within the solids. The waste stream is then
thoroughly mixed under pressure with aspirated air utilizing micron-size bubbles to
produce an exceptional oxygen transfer to the liquid, resulting in a dramatically improved
environment for biological activity and thus a more rapid degradation of wastewater
contaminants. Air Jammer™
systems have several advantages over other aeration systems:
|
1) |
The Air Jammer™
has an excellent oxygen transfer to water/wastewater. As water is pumped through the Air
Jammer™ unit, at specified rates and pressure, a vacuum is
created at the air induction ports on each side of the unit. The vacuum created is equal
to approximately twice the atmospheric pressure that water and people are subjected to, 28
PSI. This pressure forces the atmospheric oxygen into the water. Once this occurs, the
oxygen can only be removed from the water by biological uptake from the waste stream or
boiling of the water. As wastewater is pumped through the unit, organics that are in the
waste stream are sheared into macroscopic size and thoroughly mixed with the oxygenated
water. This shearing of organics into smaller particles allows bacteria to digest them
easier. |
| 2) |
The Oxygen transfer
stated above for Air Jammer™ units
is equal to:
| Model M-2 |
15 pounds per hour |
| Model M-3 |
27 pounds per hour |
| Model M-4 |
50 pounds per hour |
| Model M-6 |
101 pounds per hour |
|
| 3) |
The Air Jammer™
system is a land-based system allowing ease of installation and increased safety for
maintenance requirements. |
| 4) |
The Air Jammer™
system pulling water or wastewater from the bottom or near bottom of a lagoon or tank
gives mixing from bottom to top and circulation in clockwise or counter-clockwise
direction. This mixing and stirring greatly improves operation of any system and will stop
temperature inversions and the odor problems caused by the changing of the seasons. The
Air Jammer™ will not create odors. |
| 5) |
The Air Jammer™
will place more oxygen in the water for less electrical cost than any other system
available today.

Metcalf & Eddy, Inc. McGraw-Hill, NY, NY 1991Surface aerators beat atmospheric oxygen into water that already has oxygen in
it. Venturi aeration is configured to bring the most anoxic (oxygen-deficient) water into
the venturi. This is where the venturi can achieve higher transfer rates of dissolved
oxygen because there is less resistance at the air/liquid interface. Most aerators use the
buoyancy transfer model for dissolved oxygen. The venturi (Air Jammer™) uses the
kinetic oxygen transfer model where the liquid is converted into macro-droplets of water
and is imploded with 2.2 volumes (twice the atmospheric pressure) of ambient air to one
equivalent volume of liquid. Transfer takes place predominantly within the "mixing
and oxidizing" zone of the Air Jammer™. |
The Air Jammer™ must be installed in a horizontal position and discharged above
liquid level.
