Correction to: Enhanced Oxygen Volumetric Mass Transfer in a Geometrically Constrained Vortex (Water, (2022), 14, 5, (771), 10.3390/w14050771)

There was an omission in the original publication [1]. The authors showed SOTR values in a figure but did not mention how these values were calculated. As a consequence, the calculations based upon the SOTR also need to be more specific, which is why “the twisted regime of” has been added in front of “the hyperbolic funnel”. An addition has...

Enhanced Oxygen Volumetric Mass Transfer in a Geometrically Constrained Vortex

Aeration is one of the most cost intensive steps in water and wastewater treatment due to the large energy requirement for the creation of large surfaces for sufficient gas exchange as well as for providing efficient liquid transport in order to exchange saturated liquid elements at the surface with unsaturated ones from the bulk. In this...
