Types and characteristics of aerators

Roots blower is small in size, simple in structure and easy to use. It is suitable for conveying non-corrosive, non-viscous, dry, solid-free or small amounts of solid-free gases. It is widely used in industrial manufacturing and equipment, such as water treatment, sewage treatment, mining, chemical industry, electronics and construction. In aquaculture, especially as fish pond oxygenation equipment, Roots blower can provide stable gas flow and pressure to promote the dissolution of oxygen in water.

An air compressor is a mechanical device that converts atmospheric air into high-pressure gas. It is mainly used to drive various air tools, such as spray guns, flushing guns, air drills, and air hammers. It can also be used for painting, spray painting, punching, punching, grinding, polishing, engraving, pneumatic conveying, and some compressed air workshops. In terms of fish pond oxygenation, the working principle and application scenarios of air compressors are different from those of Roots blowers.

Induced draft fans are generally used for air supply or exhaust. They can be used as independent fans or in conjunction with other equipment. They are commonly used in large building air conditioning systems, industrial smoke exhaust systems, ventilation systems, gas boiler supply, oven air supply and other fields. Its working principle is to force the fan to send gas out or suck it into the treated area.

Mechanical aeration equipment rotates the impeller through mechanical bearings, causing violent water flow in the surrounding water, thereby increasing the oxygen content in the water. The advantage of this oxygenation method is that the cost is relatively low and the oxygenation effect is relatively obvious. For example, the impeller aerator is a more common mechanical aeration equipment. It can lift the bottom water and make it alternate with the surface water, thereby increasing the oxygen content of the bottom water. The oxygenation depth exceeds 2 meters.

Microbial aeration equipment promotes the decomposition of fish pond water by cultivating an appropriate amount of microorganisms (mainly a small amount of aerobic bacteria), thereby increasing the oxygen content in the water. An appropriate amount of microorganisms can decompose waste in the water, slow down the self-disintegration of the water, improve the quality of the water, and help the dissolved oxygen performance. Although this oxygenation method has a relatively slow oxygenation effect, it has a long-term positive effect on the improvement of the water ecological environment. At the same time, during the operation of the microbial aeration equipment, it can also promote the circulation of organic matter in the water, providing good conditions for microecological agents to regulate water quality.
