Rational use of roots aerator in aquaculture

The aerator has been used in fish ponds in high-yield areas since 1970s. Because of the large amount of fish in the ponds, fish floating heads and floodwaters are easily caused when the pool water is lack of oxygen.

It is an effective method to install oxygen aerator to ensure high yield of pond.

1-Application of aerator  

At present, roots type aerator is widely used, which has the comprehensive functions of water stirring, aeration and oxygen increasing. According to the measurement, the general impeller type oxygen dispenser can increase the oxygen in water by more than 1 kg per kilowatt hour, while the roots type oxygen generator can increase the oxygen in water by more than 23 kg per kilowatt per hour.

The roots type aerator uses the bottom to fill oxygen, so that the dissolved oxygen distribution in the upper and lower water layers is even.

The roots type aerator also has aeration function, which can make the dissolved gas in the pool water escape into the air, start up at night and in the morning, and accelerate the escape of toxic gases such as hydrogen sulfide and ammonia nitrogen in the water.

2-matching of oxygen aerator  

The power allocation of roots type oxygen increaser is determined according to the production level and the required output in each region.
