Surface Aerators

Nozzles
Nozzles are generally used in round tanks water from a pump is sent downward through a nozzle towards the surface water. When this water hits the surface water, there is considerable amount of turbulence on the water surface. This turbulence is due to transfer of energy of water leaving the nozzle. Besides increasing the dissolved oxygen in pond water, nozzle aerators also set up circular water flow.
