Water mixing and movement distributes dissolved oxygen, fertilizers, liming and other products, as well as destratifies the water column in aquaculture systems.
Muchos estanques acuícolas requieren aireación mecánica tanto para aumentar los niveles de oxígeno disuelto como para favorecer la mezcla de las aguas ricas y pobres en oxígeno, que también ayuda a prevenir el volteo.
Promoting water circulation during the day time is an effective strategy to enrich pond water with oxygen produced by photosynthesis, and can significantly reduce the costs of night time supplemental aeration. Many types of effective, commercial water circulators are available.
Many aquaculture ponds require mechanical aeration both for increasing dissolved oxygen levels and to promote mixing of oxygen-rich and oxygen-depleted waters, which also helps prevent turnover. Promoting water circulation during the day time is an effective strategy to enrich pond
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
Light penetrating water is scattered and absorbed exponentially as it passes downward. The presence of dissolved organic matter and suspended solids further impedes light penetration, and different types of solids absorb different wavelengths.
