Did you know?

After many years of research, we believe aeration to be the foundation for improving and maintaining proper water quality in ponds and lakes. Lake bed aeration acts to increase dissolved oxygen levels while eliminating water stratification.

OxyJet®

OxyJet®

Pond Oxygenation

The Patent-pending OxyJet® system can increase DO levels to over 20 ppm throughout the pond down to the sediment layer where it is needed most.

Oxygen is generated on-site and pumped into a specially designed water-oxygen contact chamber. Here, pumped pond water becomes super-saturated with oxygen and diffuses throughout the pond, all the way to the sediment layer where it is needed most.

This technology has distinct advantages over other aeration including being able to reach much higher DO levels, having low visual and audible impact, as well as being simple to install.

Kasco Diffused Aeration

Kasco Diffused Aeration

NEW Kasco’s Robust-Aire™ systems are NOW 34% quieter and easier to maintain. Newly redesigned, these systems feature a significant reduction in sound (patent pending), larger air filters on 1/4HP and 1/2HP systems for less frequent cleaning, and a visual maintenance indicator to alert when maintenance is needed.

Robust-Aire™ systems pump compressed air from a shore-mounted compressor through self-weighted lines to a diffuser on the pond, lake or tank bottom. The diffuser then continuously releases micro-bubbles that rise to the surface carrying large volumes of water. This induces oxygen-transfer as well as beneficial water movement and mixing.

All Robust-Aire™ diffused aeration systems are available with an optional remote manifold allowing the compressor to be installed up to a mile away from the water’s edge

Kasco Surface Aerators

Kasco Surface Aerators

Kasco Surface Aerators are the clear market leaders, with more installations than any other manufacturer. Independent testing at Auburn University found that Kasco’s aerators’ SAE (Standard Aeration Efficiency) is up to 3.0 lbs of oxygen per horsepower per hour of operation, making them some of the most efficient and effective units available.

Kasco Surface Aerators dramatically agitate high volumes of water at the surface, maximizing air and water exposure to create valuable gas exchange. Surface Aerators are your best choice for aeration when a decorative fountain pattern is neither necessary nor desired.

Bubble Tubing Aeration

Bubble Tubing Aeration

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.

Fine Bubble Technology at work

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.  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.

Bubble Tubing® optimises oxygen transfer and lifts water which aids in total circulation throughout the water column.  As it functions without moving parts or electricity in the water, it increases performance efficiency while significantly reducing electrical and maintenance costs in comparison to other aeration systems.  This tubing, made of highly resistant yet flexible PVC, is non-kinking and holds no memory when deployed.

Features of Bubble Tubing®

  • 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, impressive 5-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.

Operations: 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.

Silt Barrier and turbidity curtains to contain sediments in suspension

Bubble curtains also meet the requirement for containing silt and turbidity for in-situ work where sediment containment barriers are mandatory. When operating in a stream, river or lake, marine construction and dredging companies are required to install a physical curtain called a floating turbidity barrier.lick on picture to enlarge

These obstacles do not allow free passage for boats and work equipment. Whereas a bubble curtain does both: it allows movement of boats and equipment over the barrier while retaining sediment and other suspended matter. In this case, a bubble curtain installed from the stream, river or lake bed will mitigate the migration of silt and other suspended sediments through the water column.

Our Bubble Tubing® has proven to be very useful as a silt barrier and turbidity curtain during these applications. Also, in this article, research is currently underway to validate the effectiveness of bubble curtains in altering stream dynamics. Water currents in the outer curves of riverbeds are slower allowing for sediment deposition and accumulation.  Over time, a sand bank can be created, making shipping impossible without dredging under certain circumstances. By installing a bubble curtain in this outer curve, this creates a sufficient current to prevent sediment buildup.

These are a few of the applications for Bubble Curtains. We look forward to working closely with engineers, scientists and water managers to find bubble curtain applications to protect wildlife and the environment so projects can move forward in an environmentally responsible manner.
