It can also be used for irrigation when the spray nozzle is taken away ,the shift of such two functions donâ??t need any tools. It was tested by the STBS .The oxygen transfer capacity and power efficiency exceed the National Agriculture Department Standard (about more than 60 percent ). 3.The paddle wheel aerator let shrimp, eel, fish and other aqua animals can grow up quickly and healthly and can be avoided to die because of lack of enough disssolved oxygen in the water, meantime, can be farmed in high density with steady output. Features of Paddle Wheel Aerator 1. High quality motor expertise design for aquaculture industry. 2. Low friction gear reducer with low resistance to decrease energy losses. 3.Sturdy stainless steel Frame ensure without any deformation and high durability. 4.High performance impeller, replaceable paddle,low maintain cost. 5.HDPE float resist impact, acid-alkalinity and sun exposure, one piece blow molded. Working Principle of Paddle Wheel Aerator High-speed-working impellers splash the water into the air â?? these splashing water mix the oxygen in the air and brought into the water â?? the dissolved oxygen in the water increase. The working impellers produce waves and currents â?? make the saturated ammounia, CO2, methane, sulfureted hydrogen, etc. go out of the water â?? the water quality improved.
