摘要: In this review, the literature on surface aerators is critically analysed. a number of studies, critical speed for onset aeration has been correlated with geometry system and operating conditions. The studies rate aeration, gas hold-up, mass transfer coefficients are inadequate design scale-up. A comparison available designs, in terms coefficient presented. mathematical model proposed aeration. Guidelines have given selection impeller configuration overall aerators. Suggestions made future area.
