고농도 산소 용해수 생산을 위한 Ejector 개발에 관한 연구
- Alternative Title
- Study on the Development of Ejector for Production of High Concentration Oxygen-dissolved Water
- Abstract
- Effective use of water which is the most used by humankind has been emphasized. so extensive water research such as water purification and desalination are underway. In addition, high concentration water which is oxygen-dissolved by artificial methods is widely used in various industrial fields. The oxygen-dissolved water contains a large amount of oxygen gas compared with the general water so it is used in various industrial sites such as inland fish farm, waste water disposal plant, hydroponics and fish transportation etc. However, the production of oxygen-dissolved water is not easy for small-scale business operators due to problems such as space, budget, and the lack of operational expertise. Many researchers who have been studying the understanding and effect on oxygen-dissolved water keep focusing on studying effective ways to dissolve oxygen gas in the solution. Also, by using this technology, researchers are trying to improve further technologies of fish farming and hydroponics using nutrient solution. Therefore, it is expected that the technology utilized oxygen-dissolved water accelerating the growth of plants and animals will be improved consistently.
