Common oxygenation equipment in aquaculture includes aerators, floating aerators, disc aerators, and oxygen sprayers. The specific advantages and disadvantages are as follows:

1. Aerator: Suitable for shallow water areas, it presses air into the water through mechanical or wind power to increase the dissolved oxygen in the water. The advantages are simple structure, easy maintenance, and relatively cheap price. The disadvantage is that it consumes a lot of electricity and cannot be used in deep water areas.

2. Floating aerator: Suitable for medium to deep water areas, it usually uses a impeller type oxygen booster pump to transfer oxygen to the oxygen delivery pipe, and then releases oxygen into the water through multiple oxygen release heads. The advantage is that it can be applied to deep water areas, with stable operation and good oxygenation effect. The disadvantage is that the booster pump and oxygen discharge head need to be replaced frequently, resulting in high maintenance costs.

3. Disk aerator: Suitable for small aquaculture farms, also known as feed type aerator, it mainly increases oxygen in water through the rotation of the power bottom disk. The advantages are simple structure, convenient installation, and relatively cheap price. The disadvantage is that it cannot be applied to deep water areas, and the oxygenation effect is not as good as other equipment.

4. Oxygen spraying machine: suitable for large aquaculture farms, high-pressure oxygen spraying technology is usually used to spray oxygen into water, forming bubbles in the water, thereby increasing the dissolved oxygen in the water. The advantage is that it can be applied to different depths of water, with good oxygenation effect and a longer lifespan of the oxygen nozzle. The disadvantage is that the equipment price is high and the maintenance cost is high.

5. Three leaf Roots blower: It is commonly used in aquaculture, with a large air output and high exhaust pressure. One blower can meet the oxygen needs of multiple ponds. It is recommended that users use the blower produced by Jiangyin Zhongxin Machinery Equipment Co., Ltd.
