Benefits of Aeration

As shown in Agriculture Canada’s video animation, dugout aeration improves water quality.Before Aeration with Bubble Tubing, Pushkar Lake, India has the aeration solutions for a significant and broad customer base. The basins, ponds and lakes that receive aeration are equally diverse, as are the goals and results. The same aeration technology can solve an impressive array of water quality problems from targeting specific organics, reduction of odours, mixing and de-gassing to name a few. Learn more about how our Bubble Tubing improved water quality for an aeration project in India.

Wastewater Treatment: Municipal sewage, abattoirs, industrial composting and other industrial wastewater treatment plants turn to aeration and microbial action for nutrient removal.  Our products provide biological nutrient removal, liquid mixing, increased oxygen and oxidation, reduction of noxious odours associated with Hydrogen Sulphide (H2S) and sludge management.OCTO AIR Industrial diffuser for waste water aeration

Oil, Gas and Mineral Extraction Industries: Aeration is used for de-gassing, cooling systems, mineral recovery, oxidation, deicing for water pumping, dewatering, reclaiming and reusing produced water from oil and gas production, end pit lakes and tailings ponds created from petroleum extraction.

Agriculture, Food Industry and Aquaculture: Odour reduction in waste, improved waste water treatment, improving water quality for animal consumption, watering, irrigation ponds, deicing, and decontamination of holding tanks and lagoons are several applications for aeration in this sector.

Ponds and Lakes System: Without a pond bubbler, an older or man-made water body can become stratified and depleted of oxygen at the sediment level. During anoxic conditions, nutrients are released into the water column from the sediment. This increases nutrient load and so also, plant and algae growth.  OctoAir-10 diffuser fine bubble air pattern in lake waterIn winter, these anoxic conditions often result in fish kills as oxygen cannot replenish itself with the atmosphere. Our aeration systems can be tailored to de-stratify the water body.  This will ensure that oxygen is available at the sediment level for aerobic bacteria to decompose organic matter, and reduce available nutrients in the system. Using our aeration system, oxygen is continually available for fish, invertebrates and microbes. This maintains equilibrium in the system. Aeration systems in winter can also act as a deicing system. Deicing systems, prevent ice formation and allow gasses such as HS2 to be released and oxygen to be absorbed year round. With proper aeration a phenomenon called bio-dredging may occur. This happens, when the organic sediments are consumed and the organic layer of the sediment is depleted over time leading to increased depths.

For Industrial, Governmental and Private aeration projects visit our client projects sections of our website.

Open Channels and Rivers: Following a 2014 study, it was found that a bubble screen can influence flow patterns and bed morphology in open channels and rivers.  This prevents sediment from clogging curves in streams that must be dredged regularly to remain open for the transport of goods.

Goals of Aeration

69 days after aeration with Bubble Tubing, Lake Pushkar, India

We always start with the goals for aeration. Does your aquaculture business want to reduce operating costs while improving water clarity? Do the regulations require decontamination of holding tanks faster than your system currently performs? Is the drinking reservoir or lake contaminated with Manganese (Mn) leaving otherwise good water unfit for drinking? Or how can operational costs be reduced using bottom aeration instead of surface aerators to treat leachate in basins and retaining ponds? Proper aeration is an ecological and efficient component to address these environmental management issues.

Fine Bubble Aeration Diffusers

The fine bubbles (also called micro bubbles) from aeration systems are critical for achieving results whether oxygenating a wastewater treatment plant, using aeration to control excess nutrients such as Phosphorous (P) or controlling gas such as Hydrogen Sulphide (H2S). Fine bubble aeration can also be used for liquid mixing. Fine bubble aeration with linear Bubble TubingNot only do bubbles transfer oxygen, they move and mix, clarify and de-stratify and may decontaminate water by oxidation. The size of the bubble matters greatly for the application where finer bubbles lead to higher oxygen transfer. offers a range of aeration diffusers that perform optimally under different environmental conditions and for various applications. Contact us for inspiration and sound advice. Our proposals respect operating budgets, timelines and desired air transfer results.

Bottom Aerators Versus Surface Aerators

Surface aerators and circulators may be required for some applications, such as fish farming, where de-stratifying the water column is not desired. However, we can provide bottom aeration which only targets the hypolimnion. The importance of choosing bottom versus surface aerators is that the oxygen transfer rate is normally higher. In addition when surface tension is broken by bubbles, oxygen found in the atmosphere can be transferred to exposed water. We can help you decide which system is best for your application.

Aeration Systems Options

1. CanadianAir Diffusion Systems using Bubble Tubing

CanadianAir Diffusion Systems are custom industrial aeration systems.  They are composed of our very efficient Bubble Tubing linear fine bubble diffuser, on its own or embedded in an OctoAir-10 industrial grade diffuser, with compressors, cabinets, tubing lengths, and hardware components. All are chosen to specifically match the application.CanadianAir Diffusion System for aeration

Included in CanadianAir Diffusion Systems are the following:

  • Powerful, reliable and energy efficient compressor chosen to match the application.
  • Industrial grade linear fine bubble air diffuser system (Bubble Tubing or OctoAir-10) chosen to match the application.
  • Airline delivery hose.
  • Necessary hardware including valves, plugs, clamps, etc.
  • Canadian made, ventilated locking cabinet when required.

Every CanadianAir Diffusion System is custom designed. Pricing is quoted once the compressor type (piston, rotary claw etc.), tubing size (1/2”, ¾”, 1 ¼”), type (weighted, non-weighted), lengths (custom cut, rolls, spools), hardware and cabinet options are discussed.

As aeration specialists we use the best components to design our complete aeration systems. We know the strengths and limitations of the products we sell. We know how to combine parts for optimal performance under vastly different environmental conditions. And every system we sell is tested by us so what you see in a CanadianAir Diffusion Systems is simply the best on the market, from the industrial grade diffusers to the compressor as well as other components such as tubing, connectors, etc. With our name behind the CanadianAir Diffusion Systems, you are assured of a quality system that will reach your goals and that is backed by the best after sales service you can find.  We honour all parts and warranties, in addition to being able to do in house repairs.

CanadianAir Diffusion System Components Customized for Your Project:

Each component of a CanadianAir Diffusion System must be chosen carefully in order to build an optimal system that matches the application. Our experts can advise on the best options for compressors, airline delivery hose, diffusers, hardware and cabinetry, helping you design the most energy and cost efficient system for the application. We can also advise you on the optimal layout for an aeration project.

  • Configuration of the Water Basin, Holding Tank or Lake Bottom for CanadianAir Diffusion system diffuser selection

We look at the basin floor, its size, configuration, depth, and any important features or limitations. The basin configuration often determines which diffuser is best suited to the application. And as air diffusers vary in air transfer rate, CFM, design, cost, and maintenance, our expertise can help you decide if bubble tubing or another type of diffuser is warranted.

  • Matching the Compressor in the CanadianAir Diffusion System to the Application

The compressor is another critical component in the aeration set up.  Our expertise can help you decide the best options possible, whether a Piston Compressor, Rotary Claw or Screw compressor is best and why. Does the operation warrant a new compressor or can the system make do with existing equipment? can help retrofit an existing aeration system of any parts or components including the compressor. We also can help size the compressor when the diffuser changes, ensuring optimal performance results with minimum operational costs. Often commercial systems do not perform as well as they should simply because the compressor is not the correct model for the application. Contact us with your project details, we are here to help.

  • Airline Delivery Hose, Hardware and Cabinetry used in CanadianAir Diffusion Systems

Airline delivery hose, known as Torpedo tubing, heat resistant tubing, accessories, hardware and cabinetry are integral to an efficient aeration system layout. Consider saving tens of thousands of dollars with one larger compressor and a stainless steel custom valve system compared to an array of six blowers, each consuming more power than what is required. Our Torpedo Tubing is flexible, self-sinking and performs consistently year after year. We sell only top quality hardware and design valve systems in-house to meet specific project requirements. Our cabinets are robust, durable, ventilated and quiet. Use one of our cabinets or purchase a bare compressor and install it in an existing structure.

  • Additional Services to Support an Aeration Project using CanadianAir Diffusion Systems

Additional services include support (an independent engineer) to achieve specific oxygen transfer rate targets for Bubble Tubing or OctoAir-10 based on the results we obtained from The Evaluation of the Oxygen Transfer Capabilities report by Gerry Shell in 2011 (GSEE Inc. Environmental Engineering Service).  Compare our technology to others before you make a decision.  This could provide significant savings in equipment purchasing and operational costs.
