The ZSB type brush aerator is mainly used for three-tank or alternating oxidation ditch processes in the biochemical treatment of urban domestic sewage and various industrial wastewaters, providing oxygenation for the water body in the oxidation ditch.

This device is a horizontal shaft surface aeration device. The brush blades are evenly arranged on the main shaft. When the driving device drives the main shaft to rotate and the brush blades start to rotate, the brush body contacts the water, throws the water into the air to form a hydraulic jump, fully contacts with the air, and the air quickly penetrates into the water, thus completing the oxygenation process and driving the water flow to circulate in the oxidation ditch.

1. The driving device uses a vertical outdoor motor and a conical cylindrical gear reducer. The gears have hard tooth surfaces, featuring large bearing capacity, compact structure, small size, light weight, and stable operation.

2. An elastic pin gear coupling is used, which can transmit large torque, has a small size, allows a certain radial and angular error, and is easy to install.

3. The brush pieces are made of high-quality carbon steel (galvanized) or stainless steel, combined into a hoop type, arranged in a spiral shape, with uniform water entry, stable load, and convenient installation and maintenance.

4. The tail uses a self-aligning bearing and a floating support, which can overcome installation errors and automatically align. At the same time, it can compensate for the expansion and contraction of the rotating brush shaft caused by temperature differences to ensure normal operation.

5. The load and oxygenation capacity of the rotating brush aerator can be changed by adjusting the liquid level through the weir notch to change the immersion depth of the brush pieces.
