Application of oxygen generator in aquaculture
1. Promote the growth and development of fish
Oxygen is very important for any organism, fish living in water also need oxygen, but the solubility of oxygen in water is very small, if the oxygen in the pool is not enough, the development of various organs of fish will be slowed down, the use of high purity oxygen machine with reliable quality can effectively improve the oxygen content in the water (especially high-density aquaculture), can greatly promote the growth and development of fish.
2. Reduce fighting damage of fish
At present, the density of fish in factory farming is usually relatively high, and if the oxygen content of the water is not enough, the fish will become agitated, frequent friction between each other and lead to injury, which will impair the production of the fish pond. After the use of oxygen machine through pure oxygen, oxygen content in the water is greatly increased, and the fight between fish and fish will be reduced, so as to avoid friction fighting.
3, improve water quality to reduce disease
In addition, when there is not enough oxygen in the fish pond, anaerobic bacteria will ferment and produce harmful substances such as ammonia nitrogen and hydrogen sulfide, making the water deteriorate. Fish living in such water environment are easy to get sick. And the reasonable use of aquaculture oxygen machine, can improve the dissolved oxygen in the water, avoid anaerobic bacteria fermentation, so as to effectively reduce the occurrence of fish disease.
The purpose of fishermen farming is to have a large amount of fish, so as to obtain considerable income through aquaculture. After the use of oxygen machine can let the fry grow up quickly, the output increases exponentially, at the same time, high-quality durable oxygen machine can also improve the quality of water, to provide a good growth environment for fish. Environwateros' oxygen machine, high purity, durable, easy to operate, is worthy of your trust products
Oxygen cone is a kind of oxygenation equipment specially designed for factory aquaculture. The whole body is made of FRP high-strength material. The oxygen-enhancing effect is obviously better than similar products. Used in conjunction with other circulating aquaculture equipment such as pure oxygen generation equipment (or oxygen cylinder), it can provide high dissolved oxygen water for the highest density aquaculture.
The original intention of product development
Due to the increasing popularity of recirculating aquaculture, the density of aquaculture is also getting higher and higher, and then the requirements for the dissolved oxygen value of the water body are getting higher and higher. Taking the breeding density of Penaeus vannamei at 35 kg/cube as an example, the dissolved oxygen must be at least 16 mg/L to meet the needs of fish. This dissolved oxygen value does not include chemical oxygen demand in water, other biological oxygen demand and so on. Because the water body of high-density aquaculture contains a large amount of organic matter such as bait and fish feces that will not be removed in the future, the decomposition of these organic matter will also consume a lot of oxygen. The traditional oxygenation methods such as air aeration can no longer reach this level. The use of pure oxygen to increase the amount of dissolved oxygen in water in a powerful way has become an urgent need in the market.
The oxygen cone is made of FRP (high-strength glass fiber composite resin) by melting and winding. As a whole, it presents a pyramidal structure with a small upper and a large lower. The inlet and outlet water are connected by PVC flanges. There are sewage outlets and observation windows at the bottom.
An oxygen cone is a special pressure vessel. Its main function is to increase the pressure to force the gas to overcome the surface tension of water and passively dissolve under the condition that the gas and liquid are fully mixed. Therefore, the oxygen cone should be used together with booster pump, ejector and other equipment. The gas source adopts oxygen generator or oxygen cylinder (oxygen purity is greater than 90%)
Factors Affecting Dissolved Oxygen Value of Effluent
Similar to the solubility of gases in water, the solubility of oxygen in water* is related to temperature, pressure, etc. Again, it is related to the way the gas and liquid are mixed. Under normal pressure conditions, the traditional oxygenation method will have an upper limit on the dissolved oxygen in the water body. If air is used as the gas source, the amount of dissolved oxygen will be further limited. The use of industrial pure oxygen (purity * over 90%) greatly increases the dissolved oxygen efficiency. The oxygen cone is used in combination with pure oxygen, and the oxygen and water are fully mixed by the jet principle. When the gas-liquid contact area increases exponentially, increasing the pressure of the water body will further consolidate and strengthen the dissolved oxygen content of the water.
