1. Principle of Creating Water with Increased Pressure.

❖Illustration (Advantages of turbine vortex)

❖ Compare KTM Machine and Centrifugal Pump.

2. Micro Bubble Generator

❖ This is a device that creates fine foam by pressure dissolution method

❖ Hot Tub

The turbine vortex creates a pool to promote water dissolution by increasing the water-air contact efficiency of the gas-liquid mixture.

* It is installed between the turbine vortex shaft and the gas-liquid separation tank

❖ Separation Tank

Even though it goes through the dissolution tank and turbine shaft, the air separation efficiency is still good so it does not dissolve and separates the waste here.

3. Advantages and Differences Compared to Air Compressors

4. Three Points to Check and Confirm When Operating the Machine

① Has the flow pressure increased?

② Can air be passed in?

③ Does water escape from the gas-liquid separation tank?

Applications of Microscopic Bubbles

1. Wastewater treatment – Treated by increasing pressure to float to the water surface

❖ Very small solids suspended in water are thickened using a thickener and recovered thanks to the force of very small air bubbles generated in the water.

❖ Separating oils floating on water surface such as wastewater in food factories, kitchen wastewater…etc

❖ Diameter of microscopic bubble

▶︎ Measurement conditions
Measure the number of bubbles generated in the glass tube using an optical microscope (magnification: 200 times).
Observation object: About 0.2mm3
Injection pressure during measurement: 0.4MPa

Applications of Microscopic Bubbles

2. Ozone Disinfection – Oxygen Enrichment.
