The video shows an R&D setup that mimics the assembly inside a FreeOx™ well. Water is flowing downward in a 1¼” pipe that, for research and development purposes, is clear. The pipe is under a partial vacuum due to the pumping action of the water traveling downward in the pipe. Air has been drawn into the pipe just above the top of the early frames of the video and is being carried downward in the pipe by the flow of water.

As the water/air mixture moves downward in a FreeOx™ well, the pressure increases. The increased pressure forces oxygen (and nitrogen, argon, and other constituents of air) into the water. The higher pressure increases both the solubility of oxygen in the water and the rate at which the water can become saturated or over-saturated with oxygen.

Very little air is required. A 1:25 air/water ratio (one cubic foot of air for every 187 gallons of water) is enough to provide 100% oxygen saturation of water at one atmosphere. The air/water ratio in the video clip is 1:10, more than enough for 200% saturation of the water with oxygen.

This is a very low energy process. The water is pumped just a few feet above groundwater level, and much of the energy used to pump the water those few feet is recovered due the vacuum produced in the down pipe.

No compressors or blowers are required at the surface. Air is drawn into the process without need of assistance from a compressor or blower. The system runs silently at the surface. There is no aboveground equipment, other than the control panel that provides the power to the pump in the well and facilitates operation of the system.

The great advantages of FreeOx™ are:

  1. The ability to force over-saturation levels of oxygen into the water with a low-pressure, low-energy process that involves no aboveground equipment.
  2. The use of a recirculating well to over-saturate the water with oxygen several times.
  3. The use of a recirculating well to push the oxygen-laden water to great distances from the wells, oxygenating all of the water in the circulation zone of the well.
