There are many types of aerators, including impeller type, waterwheel type, water spray type, jet type, surge type, aerator pump, microporous aerator, etc. Different types of machines have different functions.
Water spray aerator
Principle: Pump up the poor water in the lower part of the pool and spray it up, around or forward at high speed.
Advantages: 1. It can extend the time and area of aeration and oxygenation in the air; 2. It has a good oxygenation function, which can quickly increase the dissolved oxygen in the surface water in a short time, and also has artistic viewing effects, suitable for Use in fish ponds in gardens or tourist areas. Not only beautiful, but also practical.
Disadvantages: Due to its small effective oxygenation area and poor energy consumption conversion, it is only used in parks, sightseeing fish ponds, small ponds, etc.
According to some people, it is better to use a fountain aerator when rescuing a floating head, because it can quickly aerate the surface water. At the same time, the speed of water convection is slow, which can avoid oxygen consumption by anaerobic water floating.
Impeller aerator
Principle: The impeller sucks up the oxygen-depleted water in the lower part, and then pushes it out to the surrounding, so that the stagnant water becomes living water. The water under the impeller is vigorously stirred by the blades and pipes, causing hydraulic jumps and waves on the water surface, forming a water curtain that can be wrapped in air. During the rotation of the impeller, a negative pressure is formed at the back of the water stirring pipe, so that the air can be sucked into the water through the water stirring pipe, and it is immediately stirred into micro-bubbles into the impeller pressure area, so it is also beneficial to improve the dissolution rate of oxygen in the air. Improve oxygenation efficiency.
Advantages: 1. Lift water and stir. The impeller-type aerator can elevate the bottom water and make it alternate with the surface water, so as to have the effect of adding oxygen to the bottom water. In case of mechanical failure, the maintenance is more convenient and the maintenance cost is reduced; 3. During the use process, the water flow in the middle and upper layers can be formed, so that the dissolved oxygen in the middle and upper water bodies is uniform, which is suitable for pond culture and pond first aid equipment; 4. Exposing harmful gases. The impeller aerator has a strong aeration function, and harmful gases such as ammonia, hydrogen sulfide, methane, carbon monoxide, etc. in the pool water can be effectively aerated.
