It doesn’t matter if an aeration system or device splashes, sprays, or diffuses air, the bottom line is how much surface area it creates. The surface area is where water contacts air and where oxygen transfer takes place. Smaller bubble size results in more surface area, which is why fine bubble aeration devices are superior in oxygen transfer than coarse bubble aerators. To maximize aeration efficiency in a system, an aerator must create fine bubbles while expending a minimum amount of energy. Aero-Tube™ technology meets both goals, and does so with a long-life, low-maintenance system.
The technology behind the extremely high performance and efficiency of Aero-Tube™ is our twice-patented manufacturing process which, through a unique combination of technique and raw material, creates numerous tiny pores throughout the length of the hose. These micro-pores allow the efficient transfer of air into the water. By combining Aero-Tube™ aeration tubing with an efficient clean air blower, you create a high efficiency, low cost method of aerating water.
Aero-Tube™ achieves its high energy efficiency in two ways:
- Due to the number of pores created during our manufacturing process, there is little resistance created when pushing air through the tubing. Resistance equals energy demand. By working with Aero-Tube™, you can use significantly less horsepower when compared with traditional methods of aeration (paddlewheels, aspirators, less efficient tubing).
- Aero-Tube’s tiny pore size creates extremely small diameter bubbles. The smaller a bubble of air the more efficiently it transfers oxygen into water (more surface area!). Small bubbles also take longer to rise once they are introduced into water. Slower rising, small-diameter bubbles mean more contact with the water and a much higher rate of oxygen transfer.
By creating significantly smaller bubbles, more efficiently, Aero-Tube™ products are able to deliver high rates of oxygen transfer and energy efficiency.
The mechanical aerators tested by GSEE Inc., provided from 1.7 to 3.0 pounds (0.8 to 1.4 kg) of oxygen per horsepower consumed, where Swan Aero-Tube™ aeration tubing yielded from 6 to 8 pounds (2.7 to 3.6 kg) of oxygen per horsepower used in fresh water. In salt water, Aero-Tube™ tubing supplied up to 15 pounds (6.8 kg) of oxygen per horsepower, making it the ideal choice for shrimp and salt water fish aquaculture.
