METHOD TO AERATE AIR BEING PURIFIED Russian patent published in 2010 - IPC C02F1/24 C02F1/74 

FIELD: process engineering.

SUBSTANCE: invention can be used for treatment of effluents. Air is forced via pipeline 23 into case 4 to displace water from floating section 7 into accumulation section 8, and comes via branch pipe 25 into floated product chamber 26. Then air is fed into additional case 13. Air jet coming out of lower base of additional case 13 forms air crater on liquid surface that represents paraboloid of revolution. Jet of liquid to be purified is fed into said air crater along compressed air flow axis oriented perpendicular to surface of liquid to be purified from nozzle 2 of tube 3 at high rate.

EFFECT: higher aeration of effluents.
