Good anti-blocking and anti-backflow properties. The aerator becomes ball and crown-shaped, even if the water quality of the aeration tank is complicated or runs intermittently, its surface is not easy to accumulate mud. The diaphragm perforation technology is unique and advanced, which is diagonal through the cut-out type. In addition, a special seal is set up in the top center to effectively prevent the backflow of water.
The diaphragm is highly resistant to tearing. The rubber diaphragm is ball and crown-shaped, when working, the hole opening is evenly stressed, fatigue deformation is reduced, good resilience, not easy to tear, and long service life.
Uniform air distribution, energy saving, and high efficiency. The working surface of the spherical crown-shaped aerator is relatively larger than that of the flat plate type, with small bubbles, uniform air distribution, high oxygenation efficiency, and good treatment effect. Especially when working with low air volume, it can still play this characteristic and is easy to operate and manage.
Aging resistance and corrosion resistance. The spherical crown-shaped aeration diaphragm is made of high-quality rubber, and the support tray and wedge-shaped insert are evenly made of engineering plastic. These materials have excellent physical and mechanical properties. It has excellent aging resistance and is resistant to chemical corrosion such as acid, alkali, and chemical agents.
Low impedance loss. Due to the unique anti-blocking and waterproof body backflow performance of the aerator, the backstop valve attached to the plate-type microporous aerator is removed, thus reducing the resistance of the aerator. Energy consumption is saved. Hign Quality Fine Air Aerate Wastewater Bubble Disc Diffuser
