Surface Aerators for Sewage Lagoons

Surface aerators are a popular and proven option for sewage lagoon aeration in Canada.  On top of this,  the professional-grade Kasco Marine AF-Series Surface Aerators are industry leaders, delivering up to 3.0 lbs of oxygen per horsepower, per hour of operation. These industrial aerators are available in 1/2HP to 5HP and offer strong aeration for sewage treatment. 

While these aerators have screens, the need to clear the screens can be reduced or eliminated if set up correctly. By placing two surface aerators side by side and setting them to run at alternate hours, the aerator running is usually able to clean the one that is temporarily turned off. 

Surface aerators provide a strong alternative to diffuser aeration and are best suited for certain municipal or industrial applications. Contact our biologist-led team of experts for recommendations on the aeration system required for your project.

Bottom Diffused Aeration
For Lagoons

Bottom Diffused Aeration is the most efficient and effective way to incorporate or restore oxygen levels in the water. Bottom-diffused aeration works by releasing microbubbles (2-3 mm) from the lagoon bottom, which rise slowly to maximize oxygen transfer and prompt water circulation throughout the lagoon. Bottom-diffused aeration has extensive benefits for lagoons including:

  • Decreasing BOD & COD

  • Restore oxygen to the pond bottom

  • Reduce phosphates by up to 95%

  • Reduce sedimentation

  • Encourage breakdown of organics and nutrients up to 10X faster

  • Reduce internal nutrient cycling

  • Reduce smells caused by hydrogen gas

  • Lower pH

  • Reduce algae and unwanted vegetation

We offer premium aeration brands, designed for efficiency in industrial applications and harsh winter climates, including Can-Air Aeration and Kasco Marine Robust-Aire Aeration Systems.

While our experts recommend the porous micro-bubble tubing diffusers used in the Robust-Aire and Can-Air systems, we offer all styles of diffusers, including EPDM membrane diffusers, and Can-Air Bubble Aeration Airline. Here at AEC, we can custom-design aeration plans to suit specific applications.  Contact our team of consultants for additional information!

Bubble Aeration Airline for Lagoons and Reservoirs

Perforated aeration bubbling air line

Bubble Aeration Airline is an easy, efficient, and effective way to add aeration to any body of water.  Bubble aeration airline can be uniquely placed at the pond or lake bottom, creating a fine bubble curtain. 

  • Create bubble curtains that act as barriers to noise, chemical treatments, floating debris, and more

  • Aerate easily in irregularly shaped and shallow bodies of water 

  • Restore oxygen to the pond bottom

  • Decreasing BOD & COD

  • Reduce phosphates 

  • Encourage the breakdown of organics and nutrients

  • Reduce smells caused by hydrogen gas

  • Lower pH

  • Reduce algae and unwanted vegetation

For typical bodies of water that require aeration, we will usually recommend bottom diffusers made with micro-bubble aeration tubing, however, our experts understand that every pond, lake, lagoon, and project is unique. This is why Can-Air Bubble Aeration Airline has become a staple in our aeration lineup. Contact our team for more information. 

Aerating Fountains for Municipal & Commercial Ponds

Aerating fountains provide superior aerating performance, coupled with a beautiful visual display. Kasco Marine offers their ever-so-popular VFX aerating fountain as the ideal solution for municipal and commercial ponds and lagoons requiring aeration while providing visual appeal. These units are efficient and easy to install and operate. 

Aerating fountains aid in the evaporative cooling of ponds while providing rich oxygen near the surface. These fountains are available in 1/2HP to 5HP units making them ideal for smaller ponds to large bodies of water requiring aeration. 

Aerating fountains are a form of surface aeration that provides a classic V-shaped display while being alternative aeration to bottom-diffused aeration, thus, are best suited for certain municipal or commercial applications. Contact our team of experts for an appropriate model to suit your needs!
