The fish pond aerator is an indispensable tool for modern aquaculture. Its main function is to increase the oxygen content in the water to ensure that the fish are not hypoxic. At the same time, it can also prevent the deterioration of the pond water and the growth of anaerobic bacteria in the water, which threatens the fish. Class living environment. There are several types of aerators commonly used in China. The manufacturers of aerators sort out the advantages and disadvantages and applicable conditions of different aerators as follows:
Water wheel aerator
It has a good effect of increasing oxygen and promoting the flow of water. It is suitable for ponds with deep silt. It has a strong pushing effect and obvious oxygen increase on the surface of the water body. It is generally suitable for shrimps and crabs.
It has the comprehensive effects of aeration, water agitation, and gas explosion. Its aeration capacity and power efficiency are better than other models, but it has higher operating noise. It is generally used for large-area pond culture with a water depth of more than 1 meter. The oxygen machine has good power effect and large working area, which is suitable for breeding four major domestic fishes.
Water jet aerator
It has a good oxygenation function, which can quickly increase the dissolved oxygen content of the surface water body in a short period of time. At the same time, it also has an artistic appreciation effect. It is suitable for use in gardens or fish ponds in tourist areas. Water jet aerators can increase oxygen in small ponds, but large-scale aquaculture is really not suitable. It is suitable for small fish ponds and fishing grounds in garden-style tourist areas.
Its aeration power efficiency exceeds that of waterwheel, aeration, water spray and other forms of aerators, and its structure is simple, and it can form water flow and stir water. The jet aerator can increase the oxygen in the water gently without damaging the fish body, and is suitable for aeration in the fry pond. Jet aerators are suitable for deep-water aquaculture and longer ponds.
The air is sent into the water through negative pressure suction, and mixed with the water to form a vortex to push the water forward, so the mixing force is strong. Its aeration capacity for the lower water is stronger than that of the impeller type aerator, and its aeration capacity for the upper water is slightly inferior to that of the impeller type aerator. The deeper the water of the inflatable aerator, the better the effect. It can dissolve oxygen up and down gently, without damaging the body of fish and shrimp. It is suitable for aeration in fish and shrimp fry ponds, but if the bottom of the pond is silt, it is not recommended to consider it. ,the cost is too high.
