Feature

Enlargement of contact area of gas–liquid – Generation of micro bubbleIncrease of contact time of gas-liquid – Generation of micro bubble at normal pressureMaximization of gas dissolubilitySmall sized compact design – Minimization of installation spaceMaximization of oxygen transfer efficiency – Accomplishment SOTE over 90%Diffusion & reflection effect – Enhancement of ultraviolet rays energy utilization efficiency with uniform distribution of ultraviolet rays irradiationVortex (mixing) effect – Generation of vortex (mixing) in the effective range of sterilization by rising of micro bubble
- Enhancement of sterilization efficiency by increasing contact frequency between ultraviolet rays and colon bacillusBubbling effect (Enlargement of superficial area of microorganism exposed to ultraviolet rays
- Effect of Biological Activity : Individual separation of microorganisms by providing DO to microorganism with lowered activity
- Physical Chopping effect : Separation of microorganisms to small unit by impact energy of bubble breaking Droplet effect – Microorganisms is adhered to the surface of micro bubble and is sterilized in concentration by diffusion / reflection inside and outside of bubble

Principle of Generator of Micro Nano Bubble

Water supplied with pressure of 2~3kgf/cm2 is circulated in vacuum area in high speed, so that it leads the degree of vacuum in that area to be 400mmHgIf vaccum is formed. the inflow of outside air is made and the air becomes bubble by mixing with liquer.It is the stage of liquid and air inflow. which is the process of mixing air with fluid.Nano bubble is formed in a moment by the spiral Energy with rapidly incressed flow spead.Concept drawing of NANO Bubble Generation

Theory for Micro Nano Bubble Technology Application

Self Pressurization Effect
As the volume of liquid dissolved gas under the specified temperature is to be dissolved in proportion to the partial pressure of corresponding gas. Which demonstrates the higher solvency with the more minute bubbles, in theory the pressure inside the bubbles become infinite at the moment of extinction, As a simplified comparison, the gas solvency of 10µm bubble with diameter is approximately 20,000,000 times of 1mm diameter bubble.

Electric Potential Characteristic of Micro Nano Bubble
Smaller size bubbles demonstrate the better washing effect with higher adhesive force even in comparison with the particles of high zeta potential. Moreover, the oxygen amount per unit volume is increased enhancing the sterilization effect when the size of bubble is within the range of nano level. In other words, the minuteness of bubble size increases the washing or separation enhancing the sterilization effect accompanied with the increase of dissolved oxygen volume.

Compressive Fracture Characteristic of Micro Bubble
Compressive fracture characteristic is a well known symptom in ultrasonic engineering. Which produces the extremely high temperature of 4,000 ~ 6,000°C instantaneously with Self Pressurization Effect generated by the gas pressurizing force of surface tension residing inside the bubble and disappear after repeating the chain reactions of pressurizations and bursts within instant of 1 out 1 million second. At this moment, the generation of free radicals such OH & etc., decomposes the bacteria and harmful chemical substances residing inside water.

Adhesion Characteristic of Micro Bubble
The smaller sized bubbles provide the ease of infiltration allowing the adhesion with particles against the high electric potential. At the moment, the cleaning process becomes effective as the relative gravity of particles is decreased once the particles and bubbles are adhered together.
