Aire-O2® Microfloat DAF (Dispersed Air Flotation System)

Dispersed air flotation

Aire-O2 Microfloat Dispersed Air Flotation System

Ideal for industrial applications, our Aire-O2 Microfloat Dispersed Air Flotation (DAF) System is an effective, affordable and reliable physical/chemical pre-treatment technology for removing up to 90% free-floating FOG, 60% TSS, and 30% BOD*– all at a much lower cost than traditional DAF systems. The Aire-O2  Microfloat DAF simply disperses the air using a high RPM, 2900RPM 50Hz and 3600RPM 60Hz, aspirator directly into the tank. The DAF has a specially designed non-clog spinning disc diffuser that creates fine microbubbles (10-50 microns in diameter), allowing for high removal efficiencies. The complete Microfloat DAF system uses only two motors; the Microfloat aerator motor and the scum/rake drive. The Microfloat DAF system does not require an external recycle line.
