Application of Low-Speed Propeller
Low-speed propellers are suitable for aeration tanks and anaerobic tanks in industrial and urban wastewater treatment plants. They generate strong water flow with low tangential velocity, which can be used for water circulation in tanks and creating flow during nitrification, denitrification, and phosphorus removal stages.

They are applied in oxidation ditch propulsion, mixing in various biochemical tanks, as well as river freeze prevention and landscape water circulation. They are used for mixing, stirring, and circulating in municipal and industrial wastewater treatment processes, and can also serve as maintenance equipment for landscape water environments. Through stirring, they create water flow, improve water quality, increase oxygen content, and effectively prevent the deposition of suspended solids.

The QJB type submersible propeller (propeller) mainly consists of a submersible motor, gear reducer, spiral propulsion impeller, sealing mechanism, manual hoist, installation system, and electrical control device.
