Today, microbubbles are widely used in various fields such as agriculture, medicine, pharmaceuticals, and purification. They have water and minerals, there are different methods for producing microbubbles, among which these methods can be used referred to the rotating flow (spiral flow), cavitation and the use of porous materials. In recent years Due to the advantages of the method of using a porous medium, including simplicity in design and construction, ease of installation, etc Establishment, low energy consumption and easy maintenance and repair, extensive studies have been done on this method Various commercial devices have been produced based on this method. The purpose of this research is to design and build a The microbubble generator is a porous medium method; Therefore, in the beginning, the studies conducted in this area and Existing designs for microbubble generators have been reviewed. Then after choosing the desired design The design parameters and their effect on the performance of the microbubble production process have been investigated. In the end, then Finalizing the design of the device and the design parameters of the device, the manufacturing stages of each part and the manufacturing challenges It has been reviewed and mentioned. After the construction of the desired device, some practical tests have been taken from the device Its results have been mentioned. The results of this research and previous researches show that with the increase of discharge, pressure The entry of water and the amount of porosity, the diameter of microbubbles decreases, and this factor causes the life span and number The production of microbubbles can increase and it was also determined that a pump with a suitable head can be selected It is very important, if you choose a pump with a high head, there will be a suitable pressure drop in the suction part of the device It does not give and as a result no bubbles are produced.
