The paddle wheel aerator is a water oxygenation equipment that is efficient, intelligent, and easy to maintain and repair. It is of great significance in improving water quality, promoting biological growth, and purifying water sources.

What is a Paddle Wheel Aerator?

Paddlewheel aerator, also known as propeller aerator or paddle aerator, is a highly efficient water oxygenation device. The following is a detailed introduction to paddlewheel aerator:
1. Definition and working principle
Definition: Paddlewheel aerator is a device that increases the dissolved oxygen content of water by inhaling and dispersing air into tiny bubbles through the rotation of a propeller or an axial flow pump impeller.
Working principle: When the propeller or axial flow pump impeller rotates, negative pressure is generated to inhale air, and the air is broken into tiny high-density mist bubbles under the impact of high-speed water flow. These bubbles then diffuse to the middle and lower layers of the water body, greatly increasing the gas-liquid mass transfer interface, prolonging the time the bubbles stay in the water, and thus improving the dissolved oxygen efficiency.
2. Structural composition
Paddlewheel aerators are usually composed of the following parts:
Motor: Provides power to drive the propeller or axial flow pump impeller to rotate.
Float body: Enables the equipment to float on the water surface, which is easy to install and move.
Adjustment bracket: Used to adjust the angle and height of the equipment to adapt to different water environments.
Hollow shaft: connects the motor and propeller to transmit power.
Support sleeve, guide cover, propeller and guide tube and other components: work together to ensure that the air is effectively inhaled and dispersed into tiny bubbles.
3. Performance characteristics
Efficient oxygenation: by generating tiny bubbles, the gas-liquid mass transfer interface is greatly increased, and the dissolved oxygen efficiency is improved.
Large stirring area: the rotation of the propeller can stir a large area of water, promoting the convection exchange of bottom oxygen and high-level oxygen in the water body.
Intelligent control: Some paddlewheel aerators are equipped with intelligent control boxes, which can automatically start and stop the equipment according to the dissolved oxygen content of the water body, saving energy and improving efficiency.
Easy maintenance and repair: Since most of the parts are arranged on the water surface, maintenance and repair are relatively simple and convenient.
4. Application field
Paddlewheel aerators are widely used in aquaculture, water treatment, sewage treatment and other fields. Specific application scenarios include fish ponds, shrimp ponds, breeding ponds, lakes, rivers and other places where the dissolved oxygen content of water needs to be increased.
