Surface aerator

The surface aerator in aquaculture is a device designed to improve water oxygenation by creating dynamic movement at the surface of the aquatic environment. Typically powered by an electric or thermal motor, it generates turbulence that promotes air intake and mixing with the water, thus increasing the dissolved oxygen concentration.

The operating principle relies on the formation of fine air bubbles or the creation of surface agitation, which facilitates gas exchange, optimizing oxygen absorption and carbon dioxide expulsion. This is particularly crucial in intensive aquaculture systems, where oxygen demands are high due to the density of aquatic organisms.

Surface aerators are usually equipped with adjustable blades or diffusers, allowing the oxygen flow to be tailored to the specific needs of the system. They are designed to withstand challenging aquatic conditions, offering enhanced durability and efficiency. Their use also helps prevent dead zones and improves water circulation, ensuring better nutrient distribution and optimal waste management.

They are primarily used in ponds, intensive farming tanks, reservoirs, and aquaponic systems. By optimizing oxygen management, the surface aerator plays a key role in maintaining the health of aquatic species, reducing the risks of hypoxic stress, and improving production yields.
