Bubble Tubing®, Fine Bubble Linear Diffuser

Exclusive to CanadianPond.ca, the Bubble Tubing® is a linear air diffuser for aeration, de-icing and curtain of bubbles. It is designed and manufactured in Canada to our specifications. They provide substantial and efficient transfer of oxygen to the water. Since its establishment in 2003, we have developed our product. We have expanded the options. We are now able to meet the growing number of requests from all continents for our air diffuser hose.

Fine bubble diffusers such as our Bubble Tubing® produce many tiny air bubbles (less than 1 mm in diameter). Tiny bubbles rise steadily from the floor of a wastewater treatment basin or the bottom of waterways and canals, ponds, lakes or lagoons. These bubbles provide substantial and efficient mass transfer of oxygen into the water. This oxygen, combined with the food source, sewage or sediment, allows naturally occurring bacteria to produce enzymes. Enzymes help break down waste or sediment made of accumulated organic matter.

  • Bubble Tubing® is flexible, it holds no memory and will not kink, is easy to install and is safe for the environment (does not contain lead).
  • Made exclusively in Canada to our exact specifications, 1-year warranty.

  • High oxygen transfer rate. A full evaluation of the oxygen transfer capabilities by independent firm available.
  • Applications range from farm ponds to the largest industrial projects.
  • Suitable for fresh and saltwater applications, from shallow to deep waters.
  • Inner pressure prevents clogging; tubing is low maintenance, anti-fouling.
  • No moving parts or electricity in the water.
  • Highly resistant PVC (chemicals, salinity, temperature).
  • Weighted and non-weighted formats available.
  • Tubing can be purchased with all the necessary hardware, ready to be installed.

The size of the bubble matters greatly for the application as we have noticed in our work. The fine bubbles (microbubbles) are critical for achieving precise results whether oxygenating a wastewater treatment plant, using aeration to biologically remove excess nutrients, or using aeration for fluid mixing. Deicing and air bubble curtains applications that rely more on mixing and moving water also benefit from billions upon billions of microbubbles produced by Bubble Tubing®. Not only do bubbles transfer oxygen and decontaminate water by oxidation, but they also move and mix, clarify, and de-stratify water. Thus the same technology has many diverse applications.

For de-icing, the bubbles that come out of the Bubble Tubing® carry dense, heavy and warmer water from the depths to the surface. This movement of warmer water towards the surface inhibits the formation of ice.

Bubble Tubing® Test Results

In 2011 we tested the oxygen transfer capabilities of Bubble Tubing® by an independent firm, GSEE Inc of Laverne, Tennessee. The tests were carried out on the ½”, ¾” Bubble tubing® and the OctoAir-10 industrial diffuser. In the summer of 2017 we gave an other mandate to GSEE Inc. to test the Bubble tubing® at higher airflows and deeper depths, while also carrying out testing on our 1” Bubble tubing® and OctoAir-60 industrial diffuser.

“Overall, the results obtained for the CanadianPond.ca Products Ltd. aeration systems were uniformly excellent and produced some of the highest SOTE values GSEE Inc. has observed.”

How does Bubble Tubing® work?
Compressed air enters the tubing creating an inner pressure. It is released through the perforations thanks to the precision holes found along both sides of the entire length of tubing. The ensuing micro-bubbles are efficient in preventing clogging and fouling (typically found in porous diffusers), of the entire length of tubing. They form a bubble curtain of uniform and evenly dispersed fine bubbles.

CanadianAir System Plan witn Bubble Tubing® fine bubble diffuser

No matter the scale of operations the same basic principle applies: A compressor’s heat hose is attached to the airline delivery hose which itself is connected to the Bubble Tubing® equipped with a check valve. The compressor pushes the air through both the feeder hose and the diffuser tubing that releases the air uniformly into the water.

We offer all the necessary products from start to finish, to fully set-up a reliable and efficient aeration system for you. We can size the compressor for the application, suggest tubing layout, suggest cost effective design modifications, and offer to troubleshoot. Our experience designing aeration and deicing systems with Bubble Tubing® is substantial, and our expertise is sought for many aeration projects.

Aeration, Deicing and Air Bubble curtains applications include (but are not limited to the following):

  • Aeration sewage lagoons, wastewater treatment process plants, leachate ponds, etc.
  • Earthen ponds, dugouts, lakes, etc.
  • Waterways and channels
  • Stormwater retention ponds
  • Septic systems
  • Aquaculture
  • Deicing docks, power plant water intake, marina slips, shoreline and water retention structures, industrial ship Air Bubble Curtain with Bubble Tubing® 
  • docking, ocean freight & maritime transport, pumping operations and nuclear power generating plants.
  • Efficient Bottom-to-Top Water Circulation and Mixing for water treatment, deicing, and other application
  • Pathogen Reduction, the bubbles lift deeper waters to the surface for UV exposure.
  • Underwater Air Bubble Curtains for:
    • protecting fish and marine mammals from underwater blasting and pile driving noise
    • diverting marine mammals away from offshore oil platforms and wind power farm construction and continuous operation vibrations and noises (machinery and engine noise)
    • containing oil spills within a given area
    • controlling movement of marine life, plants and debris. A bubble barrier can control the movement of marine life, floating debris, migration of jellyfish, fish, seagrass, debris, sediments, etc
    • For efficient circulation, from the bottom to the top, in the water column and the mixture of water for treatment purposes,
  • Water Quality improvement for increasing water clarity, reducing algae blooms and reducing H2S Hydrogen Sulphide production for odour suppression.
