Gasion Airtec

Hydrodynamic Fine Bubble Diffusers Aeration for Wastewater Treatment.

The Gasionrnhydrodynamic mixers are constructed of engineering plastics and can be used asrnhigh-volume air diffusers. Compressed air enters at the bottom of the diffuserrnassembly through an ejector device creating a vacuum that draws in a largernamount of water through the aerator body. The water and air mixture gets mixedrnthoroughly in a vane-type arrangement and then the air is fractured intornmicrobubbles in a set of mushroom-type bubble breaker devices which forciblyrndissolves oxygen into the water. Circulating flows are formed by powerfulrnupward air flows that evenly churn the entire tank resulting in high agitationrnand oxygen transfer. The volume of activated sludge sucked into the aerator isrnabout 1.3 times that of the air supplied because of the strong negativernpressure created in the ejector assembly. The air discharge opening is aboutrn30mm and so operated without any clogging issues even in liquid with largernparticles.
