    ? ? In aquaculture, sewage treatment and other water treatment industries. It is very important to increase the oxygen content in water. High Dissolved oxygen can make aquatic animals and microorganisms live and grow better. It can significantly improve the efficiency of aquaculture and increase the content of probiotics in water. Especially in high density aquaculture, high Dissolved oxygen is maintained all the time. Once Dissolved oxygen is insufficient, it will produce quite serious consequences.

    How to increase the Dissolved oxygen in water body effectively, reduce energy consumption and improve the Dissolved oxygen efficiency in unit water body. It is the ideal that aquatic product practitioners have been pursuing assiduously. At present, there are several common ways of increasing oxygen in ? the market:
    1. Water car aerator
    ? ? This is the most common. General tutang culture, most are adopted in this way. A water wheel lifts water close to the surface into the air. This increases the amount of Dissolved oxygen in the water. However, this method only fixed the water cart on the surface of the pond, and had a better effect on the water on the surface of the pond, while the water at the bottom of the pond did not form effective convection. Dissolved oxygen is not improved. And the bottom of the pond is often where fish droppings are most concentrated. In the absence of oxygen, organic matter in fish faeces breaks down into harmful substances such as toxic hydrogen sulfide. These substances are soluble in water. When the concentration of hydrogen sulfide and other substances in the water accumulates to a certain extent, it will produce fatal toxicity to the fish and shrimp in the water.

    2. Fan aeration stone (nano aeration tube)
    ? ? Small fan pressure is small, only applicable to shallow water. Generally, the water depth is not more than 80cm; Large farms will use roots fans. Roots fan pressure is large, the air output is not small. For ordinary outdoor fish ponds, relatively large electricity consumption. And roots fan is generally used with nano aerator. The diameter of the gas in the water is about 2-3mm after the nanometer aeration tube is aerated. Under the action of buoyancy, bubbles will quickly surface.
    We know that. According to common knowledge of physics, the dissolution efficiency of gas in liquid is related to the following factors: gas saturation solubility, bubble diameter, liquid pressure, contact time, etc. Under aquatic conditions, the saturation solubility and liquid pressure of oxygen in water are basically fixed, so the factors that affect the dissolution efficiency of oxygen in water are the bubble diameter and contact time. The larger the bubble's diameter, the greater the buoyancy it experiences in the water. So there's this relationship.
    Under the condition that the total gas volume remains unchanged, the smaller the bubble diameter is, the larger the total contact area between gas and liquid will be, and the higher the dissolution efficiency will be. Since the oxygen content in the air is only 21%, and the bubbles have short contact time with water, the effect of adding oxygen to the water through nano aeration tube is relatively limited.

    3. Jet oxygenation and oxygen cone
    ? ? Jet aeration is a kind of gas-liquid mixing mode. Through the venturi tube, the liquid is mixed with oxygen to form bubbles. Under the condition of fresh water, the diameter of bubbles obtained by efflux is generally 1.5-3mm. Under seawater conditions, bubble diameter is generally more than 1mm. The jet should be connected to the booster pump. Therefore, it also consumes electricity. The aeration cone can be connected behind the jet. The aeration cone is a glass reinforced plastic tank with a small top and a large bottom. When the velocity of water flow decreases, the buoyancy of bubbles gradually exceeds the impact force of water flow and tends to be suspended in the cone. That increases the amount of time it spends in the water. This increases the solubility of oxygen in water.

    ? ? But if the bubbles continue to enter the oxygen cone, the bubbles in the oxygen cone will dissolve into large bubbles. It becomes a drag on the flow. The ideal model of the oxygen cone would be broken. You're going to be less efficient at dissolving oxygen. If the gas going into the oxygen cone is pure oxygen. It would be a huge waste of pure oxygen. Therefore, the oxygen cone in use, there will be certain technical requirements.
    4. The mistake of pure oxygen increasing oxygen
    ? ? Many people use the above methods to increase oxygen in aquaculture water, but the results are often not satisfactory. Especially when high-density aquaculture or aquaculture transportation, water hypoxia will bring great losses to farmers. So many people use pure oxygen to oxygenate water. But through our visits and observations. Most people are found to use a combination of nano aerators and pure oxygen (oxygen cylinders). The bubbles are between 1 and 3mm in diameter, and most of the pure oxygen spills out quickly, resulting in a lot of waste. At the same time, frequent replacement of oxygen cylinders also leads to a large increase in labor costs.

    Pioneering features of lanling pure oxygen dissolving device:
    ? ? In order to open up a new way of using pure oxygen to increase oxygen in water. The blue spirit water treatment equipment has carried on the bold imagination and the massive test. Pioneering invention of waste - free pure oxygen Dissolved oxygen device. It has a specially designed reactor connected to an oxygen cylinder, allowing water and oxygen to mix and dissolve with minimal power consumption. The water with high Dissolved oxygen flows out from the bottom of the equipment, and there is no bubble in the water. The water level in the container is controlled by the automatic control system. To prevent pure oxygen leakage. The Dissolved oxygen value of the effluent from the equipment is high but there are no bubbles. Pure oxygen is not wasted.

    ? ? Theoretically, one kilogram of pure oxygen is needed to add 1PPM of Dissolved oxygen to 1,000 cubic feet of water. But in fact, the traditional way of adding oxygen can consume up to 60 kilograms of pure oxygen. That is to say, the utilization rate of pure oxygen in water is not more than 5% by means of ordinary nano aeration pipe and jet device. The Pure oxygen Dissolved oxygen apparatus can achieve 100% utilization of pure oxygen. Greatly reduce the cost of oxygen and the labor cost of replacing oxygen cylinders.
    In the application of tutang, the inlet flow of the first pure oxygen Dissolved oxygen device is 13T/H, driven by a 1.85kw water pump. Dissolved oxygen in water was 6.7 PPM and Dissolved oxygen in water was 25.3 PPM. The Dissolved oxygen efficiency is 100%, the Dissolved oxygen rate is about 100G/H, and the Dissolved oxygen rate is 100G/ hour. Take a 5-mu tutang as an example, with the total water volume of 5000 cubic meters, add 3ppm Dissolved oxygen to the tutang water, only 15KG of pure oxygen, electricity consumption of about 10 degrees.

    ? ? Both the Dissolved oxygen efficiency and the overall energy consumption have made a qualitative leap compared with the previous oxygen increasing methods.

    ? ? High Dissolved oxygen in the effluent of pure oxygen dissolving apparatus can be mixed and diluted with the effluent of filtration system. In circulating aquaculture. We recommend that a pure oxygen dissolver be placed at the front of the biofilter. The flow of highly Dissolved oxygen to the biofilter will help the rapid reproduction of probiotics in aquatic products.
