Aeration

Wastewater and Effluent Treatment

Industries today face significant challenges in meeting increasingly strict environmental regulations for wastewater, effluents, and other types of leachate.

At the same time, rising energy costs, environmental impact, and carbon footprint concerns are pushing decision-makers to adopt solutions that are both sustainable and cost-effective over the long term. Studies indicate that 30% to 70% of the total energy consumption of a wastewater treatment plant is attributed to aeration.
With Bubble Tubing®, you can significantly improve both the energy efficiency and biological performance of your system. This results in lower operating costs (OPEX), while maintaining a low initial investment (CAPEX).

What is the Best Solution in Liquid Aeration?

With over 20 years of proven performance, Bubble Tubing® is a reliable and cost-effective aeration solution designed for a wide range of applications, including:

• Lakes and ponds
• Reservoirs and lagoons
• Wastewater treatment plants
• Drinking water tanks
• Leachate ponds
• Aquaculture and fish farms
• Stormwater retention basins
• Irrigation canals
• Industrial pits and underground reservoirs
• Sewers, pipelines, dams, and more

Bubble Tubing® systems are engineered to meet regulatory requirements across various aeration applications. They use a combination of diffusers, compressors, and established engineering practices to ensure consistent performance.

How Does Bubble Tubing® Work?

The Bubble Tubing® system is a fine-bubble aeration solution designed to maximize oxygen transfer efficiency while maintaining optimal water quality. The diffusers are available in two configurations: non-ballasted or ballasted, depending on the application.

Flexible Installation Options

• Ballasted systems are weighted to remain securely on the bottom of a water body while in operation. They are especially suitable for environments with water currents, without requiring burial or disturbing sediments.
• Non-ballasted systems are used where currents are minimal and additional weight is not required.

Targeted Aeration at the Source

The greatest need for aeration is typically found just above the sediment layer at the bottom of water bodies. However, disturbing these sediments can release unwanted pollutants.

Bubble Tubing® addresses this challenge by:

• Delivering fine bubbles precisely at this critical level
• Providing efficient oxygen transfer directly where it is needed most
• Avoiding sediment disruption and resuspension

Oxygenation, Mixing, and Gas Exchange

As microbubbles rise through the water column, they perform multiple essential functions:

• Oxygen Transfer: Fine bubbles increase contact time, improving oxygen dissolution into the water
• Water Circulation: They create vertical mixing by lifting oxygen-poor (anoxic) bottom water to the surface
• Gas Exchange: At the surface, bubbles break water tension, allowing harmful gases such as nitrogen and ammonia to escape while drawing in additional oxygen from the atmosphere

The linear design of Bubble Tubing® ensures a wide, even distribution of aeration, making it more efficient than localized systems such as disc diffusers.

Biological and Environmental Benefits

Well-oxygenated and properly mixed water promotes the growth of beneficial bacteria that produce enzymes to break down organic matter and pollutants.

As a result, Bubble Tubing®:

• Enhances the decomposition of organic waste
• Reduces sludge accumulation
• Supports nitrification processes
• Improves overall water quality

Durable, Low-Maintenance Design

The linear aeration diffuser tube is engineered for reliability and long-term performance:

• Resistant to clogging
• Compatible with most chemicals and varying salinity levels
• Performs across temperature fluctuations
• Available in versions that meet food industry standards (NSF certification)

It also offers:

• Low installation costs
• Minimal maintenance requirements
• Reduced energy consumption

Proven Performance and Certification

Bubble Tubing® has been independently evaluated by Gerald Shell Environment Engineering (GSEE Inc.), which reported:

“Overall, the results obtained for Bubble Tubing® are excellent and offer some of the highest oxygen transfers that GSEE has observed.”

The system is also available in NSF-certified versions, ensuring compliance with international public health standards.
