The oxygenator manufacturer explains that the centrifugal impeller draws oxygen-poor water from below and pushes it outward in all directions, transforming turbid water into clean water. Under the centrifugal impeller, the water is actively mixed by the blades and the impeller itself, creating water jets and waves at the water surface and forming a curtain of water that can entrain air. Moreover, as the centrifugal impeller rotates, it generates negative pressure behind the impeller blades, allowing gases to be drawn into (and dissolved in) the water. These gases are immediately broken down into tiny microbubbles within the high-pressure zone created by the impeller. As a result, this process significantly enhances the rate of oxygen dissolution from the air into the water, thereby improving the efficiency of oxygenation.

　　 Aerator manufacturer Table Example, The centrifugal impeller draws the oxygen-poor water from below upward and pushes it outward in all directions, transforming turbid water into clean water. Underneath the centrifugal impeller, the water is actively mixed by the blades and the impeller itself, generating surface phenomena such as hydraulic jumps and waves that create a curtain of water capable of entraining air. Considering that during rotation, the centrifugal impeller generates negative pressure behind the impeller blades, allowing gases to be drawn into (and dissolved in) the water. These gases are immediately broken down into microbubbles and carried into the high-pressure zone of the impeller. As a result, this process significantly enhances the rate of oxygen dissolution from the air into the water, thereby improving the efficiency of oxygen enrichment.

　　Advantage:

　　1. Water aeration and mixing: The impeller-type aerator can lift the bottom-layer water, promoting its exchange with the surface water and thereby enhancing oxygenation of the bottom layer. Its oxygenation depth exceeds 2 meters.

　　2. The mechanical structure is relatively simple. It rarely experiences equipment failures during operation, and maintenance is convenient, thereby reducing repair costs.

　　3. Oxygen deficiency rescue: During use, it can rapidly generate mid-to-upper layer water currents and splashes, ensuring uniform distribution of dissolved oxygen throughout the mid-to-upper water layers—making it particularly suitable for aquaculture and oxygen-deficiency rescue operations.

　　4. Remove harmful substances through aeration. The impeller-type aerator has a strong aeration effect, effectively removing harmful substances from the water such as ammonia, hydrogen chloride, methane gas, carbon monoxide, and others.

　　Defect:

　　1. Aeration machines generally need to be fixed in one location, making it inconvenient to change their positions. Moreover, the aeration area is limited to a specific range, and when used for larger bodies of water, their effectiveness in oxygenating the bottom layer of water is relatively weak.

　　2. Oxygenator manufacturers point out that the floating buoys of oxygenators, when exposed to the air for extended periods and subjected to sunlight, are easily eroded and damaged, requiring frequent replacement.

　　3. It relies on point-source aeration, and the mechanical equipment generates relatively high noise levels, which can easily harm or injure aquatic organisms.

　　4. Centrifugal impeller aerators are not suitable for use in ponds with shallow water levels.

　　3. Illegal boat-style aerator

　　 The aerator manufacturer stated that, Compared with impeller-type aerators designed for smuggling vehicles, these aerators have slightly lower demand. However, their "artificially synthesized water flow" feature stands out—transforming clean water into flowing water. If used in conjunction with a centrifugal impeller aerator and shared within the same pond, they can greatly enhance oxygenation and water conditioning.

　　Basic principle: Two rectangular buoyancy boxes are used as flotation devices in the water. An electric motor is mounted above the buoyancy boxes, driving a central column-mounted centrifugal impeller to create ripples and generate water flow, thereby achieving an oxygenation effect.

　　Advantage:

　　1. The overall net weight is relatively light, the structure is simple, the construction cost is low, and the oxygenation effect in shallow waters is significant.

　　2. Possessing strong water-pulling capabilities and a certain level of combination proficiency in the middle to upper layers, it can achieve a relatively good contact surface between oxygen and water, resulting in high-efficiency oxygenation.

　　3. By deploying two or more boat-style aerators in the water body, it is possible to create directional water flow throughout all ponds.

　　Defect:

　　1. The upward force on the bottom water is too weak, resulting in less-than-ideal oxygenation effects in deep-water areas.

　　2. When small aquatic animals in aquaculture produce fish floatation, it is not appropriate to use this as a rescue measure for oxygen deficiency.
