The Vacuum AirLift

The Vacuum AirLift (VAL) is a new, sustainable, and efficient water treatment system. It is an innovative and versatile, yet simple, technology platform with four basic functions:

 
 
 
 

The VAL provides superior water treatment solutions for many industries, including Oil & Gas, Aquaculture, and Microalgae Production.

 

How It Works

Vacuum is used to raise water within 2 concentric tubes.

The vacuum pulls air through diffusers, which generate an airlift and, therefore, water circulation.

The bubbles rise and create a foam at the top of the VAL. The foam, filled with micro-particles, is then extracted by the vacuum.


Current Results

Water treatment is performed using less energy, and without the need for additional chemicals or consumables.

General Performance

  • Water flow rates range between 10 and 5,000 gpm per unit, depending on the use.
  • Energy consumption as low as 5 W/m^3 for water circulation.
  • CO2 stripped can range from 0.2 to 10 lbs/hour.
  • Depending on size and unit configuration, 0.2 lbs to 5 lbs of O2 can be dissolved per hour.
