The patented Laval Jet Dome Aerators, also called Laval tube-dome jet aerators, are made of stainless steel and have several series and models, which are suitable for aeration in various activated sludge sewage treatment processes.

The inner nozzle or outer nozzle of this series adopts Laval tube design. According to the Laval principle, the flow velocity of the water flow will suddenly increase after passing through the contracted neck of the Laval tube, so this series of products overcomes the disadvantages such as high energy consumption and small service area of common types of jet aeration products in the domestic and foreign markets. Compared with these products, various aeration performance indicators have been greatly improved.

Laval jet dome aerator is made of real stainless steel (AISI304, AISI316L), which is corrosion-resistant and has a service life of not less than 20 years.
