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 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 micro-bubble tubing diffusers used in the Robust-Aire and Can-Air systems, we offer all styles of diffusers, including EPDM membrane diffusers. Contact our team of consultants for additional information at or 1-855-414-7663.

Kasco surface aerators feature the highest efficiency design to ensure low power consumption. This attention to efficiency combined with lower monthly power bills, low maintenance, and a very affordable initial purchase price allows our surface aerators to have a very low total cost of ownership.


Manufactured with robust components ensures the most dependable unit motor on the market. Featuring hard-face internal mechanical seals for leak protection, long-life top and bottom ball bearings and environmentally friendly mineral oil lubrication for excellent heat dissipation.


These units thrive in corrosive and salt water environments. All external metal, motor, and hardware components are of stainless steel composition and protected by a sacrificial zinc anode. Units with stainless steel tops and double mechanical seals are available for harsher environments.


Kasco surface aerators are maintained by simply cleaning the motor housing once or twice per year and replacing the sacrificial zinc anode when visibly corroded.
