The paddle wheel aerators have the highest oxygen input per kWh

Numerous aerator comparison tests prove that paddle wheel aerators have the highest oxygen input per kWh. The easy to understand reason for this is that paddle wheel aerators create a directional flow and distribute the enriched water in the water. The re-aeration of just aerated pond water, as is inevitable with some other types of aerators, is excluded. Paddle wheel aerators of the type PWA are used tens of thousands of times in fish farms and shrimp farms worldwide. In Europe, these devices are mostly used in fish farms and larger bodies of water (lakes, ponds).
