Product name: Nanobubble Generating Device

Capacity: 300m3/h

MOQ: 1 set

Working principle

- Swirl flow type: Nanobubble Generating Device uses a pump to press the liquid into the cylindrical generator body at high speed along the tangential direction, generate a high-speed swirl inside, and use the pressure drop generated by the rotation of the liquid to crush the gas self-absorbed by the small holes on the lower end face under the shear force in the small hole in the center of the upper end face to form micro-nano bubbles.

- Micro-pore type: Use micro-porous media made of metallurgical powder, ceramics or plastics. When the compressed gas passes through the microporous medium, it is cut into micro-nano bubbles by the micropores.

Product features

- High-efficiency oxygenation: A flow rate of 300 cubic meters per hour can quickly increase the dissolved oxygen content in the water body, provide sufficient dissolved oxygen for aquaculture, sewage treatment and other fields, and promote biological growth and pollutant decomposition.

- Fine bubbles: It can produce tiny bubbles with a diameter of nanometer level, with small bubble size, large specific surface area, large contact area with water body, high gas dissolution efficiency, and can better play the characteristics of nano bubbles.

- Excellent material: The main equipment usually adopts corrosion-resistant materials such as stainless steel, such as 316L stainless steel, which can adapt to various complex water quality and environment, ensuring the stability and service life of the equipment.

- Wide application: It can be applied to aquaculture, sewage treatment, river management, soil improvement, fruit and vegetable cleaning, ship drag reduction and other fields to meet the needs of different industries.

- Energy saving and environmental protection: Compared with traditional aeration equipment, nano bubble generator has lower energy consumption and better energy saving effect while achieving the same treatment effect, reducing operating costs.

- Easy operation: Equipped with advanced control system, it can realize automatic operation, simple and convenient operation, easy maintenance and management, and reduce manual operation costs.

Technical parameters

- Processing flow: 300 cubic meters/hour

- Bubble particle size: Generally, micro-nano bubbles with a median particle size of tens to hundreds of nanometers can be produced, such as about 100nm.

- Gas flow rate: According to different application scenarios and needs, the gas flow rate can be adjusted within a certain range, such as 1-50Nm³/h (standard condition).

- Dissolved oxygen efficiency: The solubility rate of micro-nano bubbles in water is high, which can make the dissolved oxygen concentration reach above the saturation concentration, and the oxygen mass transfer efficiency is high. For example, the standard oxygen mass transfer efficiency (SOTE) can reach about 88%.

- Bubble concentration: A large number of micro-nano bubbles can be produced per milliliter of pure water, such as 2.4 billion/mL.

Application areas

- Aquaculture: Increase the dissolved oxygen content of water, improve the breeding environment, promote the growth and development of aquatic organisms such as fish and shrimp, enhance their immunity, reduce the occurrence of diseases, and improve breeding output and quality.

- Wastewater treatment: Nanobubbles can increase dissolved oxygen in water, provide sufficient oxygen for microorganisms, accelerate the decomposition of organic matter and the removal of pollutants, improve the efficiency of sewage treatment, reduce indicators such as chemical oxygen demand (COD), biochemical oxygen demand (BOD) and ammonia nitrogen, and can be used to treat industrial wastewater, domestic sewage, etc.

- River management: Aerate and oxygenate black and odorous water bodies, decompose and oxidize pollutants in water bodies, remove pollutants in bottom sludge, restore and improve the self-purification capacity of water bodies, improve river water quality, and repair water ecological environment.

- Soil improvement: Using nanobubble water for soil irrigation can increase the oxygen content in the soil, promote the activity and reproduction of soil microorganisms, improve soil structure, increase soil fertility, and be beneficial to the growth of crops.

- Fruit and vegetable cleaning: Functional micro-nano ozone bubble water can achieve harmless non-thermal sterilization, effectively remove pesticide residues, bacteria and viruses on the surface of fruits and vegetables, and can not only maintain the plant shape and original quality of fruits and vegetables, but also achieve the purpose of sterilization and extend the shelf life of fruits and vegetables.
