Impeller aerators have been widely used and continuously improved. The power has been reduced from the original 7.5 kilowatts to the current 1.5 kilowatts and 3 kilowatts, and has changed the way of diving. Now the water surface type has been added to the swing type.
Its characteristic is that the wheel rotates faster. Due to the high-speed stirring of the impeller, water splash is formed around the impeller, which raises the height of the water surface to form negative pressure. Oxygen is injected into the air through the liquid surface, and oxygen is injected into the air through aeration. Pre-existing toxic substances are released into the air.
The water body being stirred is large and the oxygenation area is relatively large, making it suitable for use on large water surfaces. It can form a water flow with a diameter of 2 to 3 meters and promote the uniformity of dissolved oxygen in the upper and lower water bodies; depending on the amount of fish, use an impeller aerator with a power of 1.5 to 3 kilowatts for 2 to 10 acres. The disadvantage is that water deeper than 3m cannot produce good water convection. The current improved swing type has been confirmed to have a good improvement in this aspect.
The impeller-type aerator has the comprehensive functions of increasing oxygen, stirring water, and exploding air. It is currently the most commonly used aerator, with an annual output value of about 150,000 units. Its oxygenation capacity and power efficiency are superior to other models, but the operation It is noisy and is generally used for large-area pond farming with a water depth of more than 1 meter.
