Wastewater Aeration

Patented Double Bubble Technology™

According to an EPA factsheet, the purpose of wastewater aeration is twofold:

  1. To supply the required oxygen to the metabolizing microorganisms; and
  2. To provide mixing so that the microorganisms come into contact with the dissolved and suspended organic matter (EPA 1999).

Wastewater Aeration

The Patented Double Bubble Technology™ utilized by the MARS Aerator is designed specifically to mix and aerate in one portable unit. The MARS utilizes fine bubble diffusers to efficiently supply oxygen, while attaining a high level of aeration energy efficiency. A coarse bubble static tube creates the mixing. This allows the microorganisms to contact with the dissolved and suspended organic matter.

MARS™ Wastewater Aeration Process

Below is a quick breakdown of the MARS Wastewater Aeration process. The unique combination of aeration and mixing allows our technology to meet the EPA definition for wastewater aeration.

See the diagram above as a reference.

  1. Mixing: Air is deployed at the lowest part of the static tube. This air is expelled first through the coarse bubble disc. The coarse bubbles, in addition to producing water turbulence, create a vacuum effect. This process lifts liquefied sludge from the bottom of the wastewater treatment cell and propels it to the surface of the water.
  2. Aeration: More air is released through the fine bubble diffusers. The fine bubble aeration results in a high level of OTE (oxygen transfer efficiency). As a result, the water column becomes enriched with oxygen. This oxygen-rich water is then primed for efficient and effective nutrient breakdown.
  3. Mixing (again): Traveling through the static tube, the liquefied sludge mixes with the air and water. It becomes further mixed and eventually dissolves amid the large bubbles and oxygen-rich water.
  4. Nutrient Breakdown: As the dissolved solids are suspended in the water column they come into contact with oxygen rich water. This oxygen feeds the metabolizing microorganisms and allows them to thoroughly break down the BOD5.
