The water spray aerator, which is used for both drainage and oxygenation, consists of a floating water pump and aeration nozzle. The nozzle can be installed to increase oxygen, and the nozzle can be used for farmland irrigation and drainage when the nozzle is removed. No tools are required for disassembly and assembly. The pump sucks into the lower layer when working. Oxygen-poor water is sprayed from the nozzle, dispersed into water droplets to fully contact the air, dissolved oxygen and falls back to the surface of the water, forming a ring of heavy rain, effectively increasing the dissolved oxygen in the water. Type: Floating, Underwater. Turbine powered aerator optional.
