Typical Application Scenarios for Bubble Tubing®
Typical Application Scenarios for a fine bubble diffuser such as Bubble Tubing®
Waste water basins, leachate ponds, composting and storm water retention ponds can achieve highly efficient aeration and circulation using Bubble Tubing®. Tubing can be installed directly in to the basin or attached to grids to allow quick removal when required.

Combining linear aeration with floating islands is a recipe for a healthy pond.
Air Bubble Curtains can be effective in absorbing sonar or blast noise from underwater detonations and pile driving. The air bubble curtains will also create an underwater fence to prevent jellyfish, sharks, salmon, shrimp and other species from entering or crossing into certain zones.
De-icing of large dams & superstructures
Bubble Tubing® installed as a deicing bubbler system at the base of a dam ensures its de-icing at all times. Single or multiple lengths of tubing fed by a large compressor can be installed at the foot of the dam face. Rising bubbles create upward flow of warmer waters and maintain open water or thin ice, as needed, preventing ice damage to the dam. Inflatable dams can also be protected using a simple Bubble Tubing® system. Dock de-icing and the de-icing of large boat slips is also a standard application.
Aeration and circulation
The principal function of the fine bubble diffuser is to aerate and create circulation. Bubble Tubing® can be used as a replacement for traditional aeration diffusers like membrane discs, air stones or out-dated plastic tubing with slits. Bubble Tubing® can be installed in wastewater treatment basins or aquaculture and shrimp farming. Whether your job requires a few hundred feet of Bubble Tubing® and a small air-pump or several thousand feet of tubing using multiple blowers with bio-augmentation, our aeration specialists will help design the most efficient Bubble Tubing® system.
Blast, sonar and noise dampening
Bubble Tubing® can provide blast dampening during underwater detonation of explosives or percussive pile driving during construction. Using an air bubble curtain will inhibit sound transmission through water due to the reflection and absorption of the sound waves by the small bubbles. The rising curtain of tightly spaced bubbles acts as a blast damper and can absorb the shock waves and other unwanted blast effects. Bubble Tubing® can also be used around harbours and military installations as a sonar muffler or sonar dampening curtain to reduce sonar noises that can harm sea life. Killer whales in Puget Sound on the Pacific Coast of North America are being harmed by sonar from the US Navy ships during military practice manoeuvres; the underwater sonar can disorient killer whales and other aquatic mammals. Reducing underwater sound levels with a bubble curtain will help with protecting whales, dolphins and other migratory creatures from the harmful effects of underwater noises like construction and blast percussion. As we wait for stricter environmental guidelines to come into play the tight-knit bubble wall created by the tubing can easily absorb sonar and other unwanted underwater noises.
Reflective pools and unique water features
Bubble Tubing® can be used to create unique patterns in reflective pools or special projects which combine lighting and surface movements. Attaching the flexible tubing to grids or shapes can allow the creation of strong geometrical patterns, straight lines and unique details lettering or images using CAD. The tubing can be used to create logos on the water’s surface or special messages during large exhibits or as special additions to monuments and parks.
Bubble Tubing® caracteristics
The ¾” Bubble Tubing® has a larger bore airline to allow for longer continuous lengths of tubing to be used. This tubing also has a solid steel cable at the center of the ballast adding extra weight to meet the requirements of salt water conditions. The wire rope at the center of the ballast also allows the tubing to be stretched taut between two points. Attaching clamps or marine connectors to the wire rope inside the ballast allows the tubing to be tightened much like a guitar string.
The ¾” Bubble Tubing® comes on reels of 200 and 400 feet, or custom lengths can be cut if required. Maximum length of a single line should be kept to 800 feet for uniformity of bubbles. Orders shipped by truck. A 200 foot reel weighs 225 pounds.
Linear aeration is a fairly recent term used to define aeration with long lengths of diffuser tubing and Bubble Tubing® is the easiest and least expensive way to maintain highly efficient linear aeration. Ecological sludge removal by diffused linear aeration is a cutting-edge technique for reducing large volumes of organic sediment from ponds and lakes.
The Europeans have a similar “linear aeration system” named after a diffuser tubing developed by Drausy. The Drausy system tubing uses a steel keel for ballast while the Canadian Bubble Tubing® uses a dense PVC solid core line for ballast. Results using the linear aeration technique are already being implemented on more than ten sites in Germany. The use of Bubble Tubing® as an effective diffuser in linear aeration has enormous potential for the restoration of lakes and ongoing projects throughout North America are showing high success rates.
Using the Bubble Tubing® can also mean adding a dramatic visual impact to your pond. This picture shows a pond with the bubbles rising from a 40 foot length of Bubble Tubing® placed in a circle in a 4 foot deep pond. A small linear compressor silently feeds air to the Bubble Tubing® and provides reliable clean air into the pond to circulate and aerate the water. Our flexible Bubble Tubing ™ can provide efficient aeration in shallow and deep ponds and hard to reach areas.
