<p>PROBLEM TO BE SOLVED: To optimally increase the oxygen transfer due to the aeration of a liq. to be treated. SOLUTION: A specified number of perforated tubes 14 are integrated with a feed mixer 6 through frames 15 and 16 at right angles to the liq. feed current 11 of the mixer 6, hence the effect of the current 11 on aeration is optimized, and the oxygen transfer is optimally increased. Consequently, the oxygen transfer is surely optimized by the effect of the liq. feed current on aeration without any skill, and further even the anaerobic agitation can be easily dealt with.</p> |
