QJB1800/2-2.2 low-speed submersible thruster for oxidation ditch
Submersible thrusters, also known as porous air diffusion devices, use porous materials such as ceramics, coarse ceramics, etc. mixed with appropriate adhesives, sintered at high temperatures to form diffusion plates, diffusion tubes, and diffusion covers. Currently, the most widely used is the membrane type microporous aeration device made by laser drilling rubber membranes. The main performance characteristics of submersible thrusters are the generation of tiny bubbles, large gas liquid contact surfaces, and high oxygen utilization efficiency; The disadvantage is that there is a large loss of air pressure and it is prone to blockage. The incoming air should be filtered in advance.
The membrane type submersible thruster adopts ABS engineering plastic as the chassis, support plate, and pressure clamp, and the air distribution membrane is made of special synthetic rubber, with a surface covered with fine small holes. During oxygen aeration, the micropores on the gas distribution membrane of the aerator can expand and open on their own under the action of gas, ensuring that gas passes through the micropores. When in a stationary state, the micropores on the gas distribution film are in a closed state. Some submersible thrusters are equipped with air valve devices on the chassis of the aerator, which prevent the mixed liquid from entering the air distribution branch pipe when the pipeline system stops supplying gas, thus avoiding the mixed liquid from entering the branch pipe and being blocked.
QJB1800/2-2.2 low-speed submersible thruster for oxidation ditch

Product Usage:
The QJB type submersible low-speed thruster belongs to the low-speed thruster series mixer, which is suitable for aeration tanks and anaerobic tanks in industrial and urban sewage treatment plants. It produces strong water flow with low tangential flow and can be used for water circulation, nitrification, denitrification, and phosphorus removal stages in the tank to create water flow.
