<p>A surface aerator for mixing gas and liquid is disclosed. The surface aerator has an upwardly pumping impeller located within a draft tube. A flow diverter redirects pumped liquid from the impeller traveling in an upward direction to a radially outward direction where it impacts and aerates the remaining liquid in a vessel. A baffle extends radially at a shallow depth to a point beyond the impact area of the liquid to provide separation of the impact area from the rest of the liquid and promote aeration.</p> |
