Aeration Industries International (AII)

Since being founded in 1974 by the late Joseph Durda and his son, Dan Durda, Aeration Industries International, Inc. has developed and applied aspirator aeration and other advanced technologies in a variety of imaginative ways to help the world’s major water users achieve and maintain clean, safe water supplies.

Our Home is in Minnesota. Our Reach is Around the World.

We’re headquartered in suburban Minneapolis where we maintain offices and a manufacturing plant as well as one-of-a kind 100,000 gallon research and development test pool facility.

There are currently thousands of installations in all 50 states and more than 85 countries around the world using our products. More than 50,000 of our trusted AIRE-O2® aerators are in operation at these sites.

The largest users of our technologies are industrial and municipal wastewater treatment plants and for water quality management to increase yields in aquaculture. Our products are becoming increasingly popular for golf course and commercial ponds, lake, river and harbor restorations.

We Share Our Experience and its Lessons.

Our expertise goes beyond product development. We also contribute articles and presentations to professional societies, journals and exhibitions. Our “Windows on Aeration” seminars for consulting engineers were introduced in 1992 and received CEU certification for 1.5 credits.

We’re Proud of Our Achievements.

We’re proud that our efforts have been recognized around the world. Aeration Industries has been the subject of Associated Press articles as well as being featured in the Christian Science Monitor and Business Week.

We’ve been covered by the British Broadcasting Company and by the Korean Broadcast Company. In a week-long series on pollution, ABC-TV’s World News Tonight profiled Aeration Industries as a “solution to pollution”.

We’ve also been ranked as a leader by Pulp & Paper Survey and Future Technology Surveys, Inc. and by the Environmental Business Journal’s “Strategic Information for a Changing Industry” report.

Looking Ahead...

Water is the lifeblood of this planet. Aeration Industries is committed to an ongoing research and development program dedicated to search for better, cost-effective technologies to preserve the world’s precious water quality and supply for the protection and benefit of humanity.

GUIDING PHILOSOPHY VALUES AND BELIEFS

• We provide challenges for our employees with opportunity for each person to take the initiative for added responsibility and growth.
• We believe in profitable growth for our long-term success.

Recognizing this common shortcoming, we focused on developing a system whereby high levels of oxygen were not only introduced, but were thoroughly dispersed as well.

Oxygen Dispersion is the Key to Efficient Oxygen Transfer

The end result is better wastewater treatment with higher removal rates of BOD and TSS. This advantage shows clearly in side-by-side tests of the AIRE-O2^® design against conventional aeration methods:

DIFFUSED AIR (1) system shows effect of air moving straight up too quickly to allow mixing. Most of the area remains unaerated.

SURFACE AERATORS (2) show minimum effective reach. Air spraying accelerates heat loss as well as allowing odors to escape.

AIRE-O2^® AERATORS (3) show complete coverage of the lagoon area. Heat loss is lessened, making AIRE-O2^® systems more effective in cold weather.

AIRE-O2^® PASSES THE FINAL EXAMS

Auburn University conducted tests in which salt and dye were injected into a one acre pond equipped with a single 2HP AIRE-O2^® unit. The effectiveness of the dispersion is visually apparent but specific conductance tests were also performed using salt injections to document the complete top-to-bottom and side-to-side mixing.
