Definitions
- the present invention relates to an air dispersing device for efficiently supplying air and other gases to a process requiring dissolved oxygen, and more particularly, to an improved air dispersing device for easy assembly and improved aeration efficiency.
- Biological treatments that selectively combine with physical and chemical methods are mainly used for the treatment of waste water.
- Biological treatments can be broadly classified into aerobic treatment and anaerobic treatment.
- Anaerobic treatment method does not require oxygen supply and has the advantage of obtaining combustible methane gas as energy, but has disadvantages such as long reaction period and generation of odor.
- the aerobic treatment method has disadvantages such as energy requirement for oxygen supply, but occupies most of the current wastewater treatment process due to short reaction time and complete organic material removal.
- the supply of oxygen is essential for the growth and activity of aerobic microorganisms, which is used for this purpose.
- the diffuser is installed inside the aeration tank and maintains proper dissolved oxygen (DO) in the aeration tank.
- DO dissolved oxygen
- An efficient way to increase the gas-liquid contact area and increase the gas-liquid mass transfer coefficient in the aeration tank is to increase the amount of bubble retention, which is essential to reduce the size of the bubbles and to generate them uniformly.
- bubbles rise as they merge with each other and increase, because the rate of rise of the bubbles increases in proportion to the size of the bubbles, and as the size of the bubbles increases, the residence time of the bubbles is shortened. If the size of the bubble is large and the bubble is not uniform, this results in a short residence time of the bubble in the aeration tank and a decrease in the standard oxygen transfer efficiency (SOTE).
- SOTE standard oxygen transfer efficiency
- diffusers such as pipe type diffusers, ball type diffusers, and disc type diffusers.
- pipe type diffusers such as pipe type diffusers, ball type diffusers, and disc type diffusers.
