Aeration tank, anaerobic tank, submersible thrusterIt is a key power equipment in sewage treatment systems, designed specifically for reaction tanks such as aeration tanks and anaerobic tanks. With its characteristics of low speed, high torque, uniform stirring, strong adaptability, and stable operation, it effectively enhances the mixing and mass transfer of sludge and water, providing a good reaction environment for microbial degradation of pollutants. It is widely used in municipal sewage treatment, industrial wastewater treatment, and other fields. ​

Low speed high torque and efficient mixing are its core performance. This thruster uses a low-speed motor to drive a propeller type impeller, which can generate powerful axial thrust and radial stirring flow fields with low energy consumption. In the aeration tank, it can evenly disperse and push the bubbles generated by the aeration system to various areas of the tank body, avoiding the problem of low oxygen utilization caused by bubble aggregation and floating, allowing the activated sludge to fully contact with oxygen, and improving the efficiency of organic pollutant degradation; In the anaerobic tank, continuous stirring is used to prevent sludge settling and agglomeration, ensuring that anaerobic bacteria are fully mixed with organic matter in the wastewater, and promoting the smooth progress of anaerobic reactions such as methane fermentation. ​

Strong structural adaptability, suitable for various pool environments. The submersible thruster adopts an integrated diving design, with a compact body that can be flexibly installed on the bottom, walls, or top of the pool through a bracket. It is suitable for different shapes of pool bodies such as square, circular, rectangular, as well as different depths of the pool (water depth can be adapted to 1-10m). For the aerobic corrosion environment of the aeration tank, its shell is made of stainless steel or polymer anti-corrosion materials; For the complex water quality of anaerobic tanks, the impeller and shaft system are made of wear-resistant materials, which can resist the wear of impurities such as sediment and fibers, and extend the service life of the equipment. ​

Stable operation and convenient operation improve operational efficiency. The submersible thruster of the anaerobic tank in the aeration tank is equipped with overload protection, leakage alarm and other safety devices. When abnormal situations such as impeller blockage and motor overheating occur, it can automatically shut down to avoid equipment damage; The variable frequency control system can flexibly adjust the speed, dynamically adjust the mixing intensity according to changes in sewage volume and pollutant concentration, and achieve energy-saving operation. In large-scale sewage treatment plants, multiple thrusters can be linked and controlled to form a collaborative flow field, ensuring uniform and consistent mixing effects throughout the entire tank. ​
