Advanced Aeration Process

| An AAP Unit |
The Advanced Aeration Process (AAP) generates ultra fine air bubbles via the ESTR HYDRO-SPARGER™. AAP is ideally suited for Dissolved Air Floatation (DAF) clarifiers and high efficiency aeration applications. The AAP technology entrains atmospheric oxygen into the waste stream in the form of micron-sized bubbles. These bubbles range in size from 0.5 microns to 5 microns in diameter.
This is a significant improvement over conventional aeration technology which produces bubbles in the 50 micron to 1,000 micron range. Due to their smaller size, the bubbles created by the AAP technology increase the lift of the contaminants, entrain more usable oxygen and stay in solution longer. Furthermore, AAP employs no compressors, blowers, or associated equipment and is driven by a recirculation pump. AAP can be employed separately as a post treatment process for the AOP in certain applications.
