Pond aeration and aerators: Second thoughts

Aerators, especially paddlewheels, are often used to mix the water and address oxygen stratification in ponds. However, most aerators do not provide the most efficient and power-conscious service. Due to thermal and oxygen stratification in ponds, the efficiency of paddlewheel aerators is low, and other present-day aerators have other problems. Emerging designs should better address effective mixing and aerating of pond water.

Oxidants are used in aquaculture as disinfectants or to enhance water quality. Hydrogen peroxide and sodium carbonate peroxyhydrate can be sources of dissolved oxygen in emergency situations where mechanical aeration is not possible.

Efectos de la aireación mecánica sobre la tasa de evaporación, temperatura del agua

Este estudio comparó la temperatura del agua y la pérdida de agua por evaporación en estanques de control y en estanques aireados con aireadores de superficie a cuatro velocidades de aireación diferentes. El aumento de la tasa de aireación aumenta la tasa de evaporación, que a su vez reduce la temperatura del agua.
