Working Principle:

The compressed air is ejected from the inner outlet of the aerator to form a gas-liquid pressure difference, so that the air and water can be well mixed.

During the ascent, bubbles are cut by three layers of venturi structure to further form smaller bubbles and increase the dissolved oxygen content in water.

The venturi structure on the inside of the aerator creates a strong pressure difference that absorbs the setting sludge at the bottom of the tank and mixes it well with the sewage and oxygen.

When the fluidized state of the software carrier through the aerator, they are squeezed between the internal venturi bulge, thus accelerating the biofilm renewal, but also enhance the efficiency of mass transfer inside and outside the carrier.
