Description
LK-QXB Centrifugal Submersible Aerator Self Aspiration aeration
Overview
| LK-QXB Submersible aerator are self-aspirating submersible aerators for wastewater and water treatment in municipal and industrial plants. The main areas of application are mixing and equalization tanks, activated sludge tanks, SBR, and sludge storage tanks. |  |
How It Works?
LK-QXB submersible aerator uses the motor to directly drive the rotation of the impeller to generate the centrifugal force. So that the nearby low pressure is sucked into the water stream, at the same time, the vacuum is also created in the inlet of impeller to suck fresh air into aeration chamber. After the water and air is mixed, it is rapidly discharged by the centrifugal force. Since the water jet is extremely strong, it will form an effective convection cycle, and divide the air into numerous small bubbles. Oxygen is dissolved in water due to the slow rise of bubbles. Due to bubbles are small, uncountable and have large surface area in water, oxygen transmission rate per unit horsepower of submersible aerators are higher than other types of aeration equipment. |  |
