After designing the special unit for two stages, the first stage was for the production of micro-bubbles and the second was for the production of Nano bubble. The production of dissolved nano bubble in water is accomplished by converting the microbubbles by high pressure (10-70 bar) and by ultrasound waves between (2-20 GHz) and at different time periods (15,30,60 seconds) and in the middle of a metal chamber that bears High pressure The results showed that the highest intensity of the presence of dissolved nano bubble in water is (24%) and was achieved at pressure (70 bar) and frequency (20 GHz) and with a time period (60 seconds).
