Dear Mohammed,
the exact calculation of the required air flow rate depends on very many parameters (such as temperature, saturator pressure&efficiency, ....). Typically you use 50-100 Nl/m3 (Nl air per m3 water) as inlet air flow for the saturator - but it can vary depending on the application. In the contact zone a typical value is 5-12 ml air / l water.
Regarding performance, the hydraulics and the geometry have a large influence, also the skimmer porperties and the chemical pretreatment.
