Surface Aerators for Sewage Lagoons

Surface aerators are a popular option for sewage lagoon aeration in Canada as well - 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 aeration system available, releasing microbubbles from the lagoon bottom, increasing oxygen levels and prompting water circulation. Bottom diffused aeration has extensive benefits for lagoons including:

  • Decreased BOD & COD

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