1 m3 of air used within the aeration works contains up to 22 thous. microorganisms, 6% of which are pathogenic. The air also contains CO2, CO, CH4, C2H6, and occasionally ammonia and other gas ingredients. That is why in the future all sewage works will be constructed in hermetic configurations and presuppose air processing. In contrast with the technology of 3, 4-step humid purification of the OTV Company, we propose to purify the air in a single or two-step scheme with the application of the new design installations.
The air used in CW is driven by a fan to the checker of installation 1 where it is contacting with the disinfecting, degasing and deodorizing solution. Further on the air, through direct duct pipelines 2 is forced to the oiling section of installation 3 where the secondary contact between the air bubbles and the solution is taking place. Then the air is ejected either to the atmosphere or to the second purification step. The solution circulation is carried out by pump 5. While the liquid flows down the collecting tray and into the pipes of air water-jet ejection 4, some part of the air is sucked in. Further floating of the air bubbles provides stirring of the oiling section 3 content and renewal of contacting surface of the "gas-liquid" phase. The new solution replenishment is taking place through mixing chamber 6.
High air oxygen use ratio of CW, the double contact between the air and the solution permit to reduce consumption of power for air processing as compared to the present technologies 3-4 times.
