Ultrasonic Sterilization

ABSTRACT

Sterilization of hospitals is one of the major concerns when it comes to hygiene and cleanliness especially during a pandemic situation. The existing methodologies include ultraviolet disinfection or hydrochloride spraying for sterilizing hospital rooms and chemical treatment for surgical and medical equipment. However since COVID strains are developing at a rapid rate, it is necessary for more efficacy and accuracy in sterilization. According to the August 2021 census collected by NCBI, 87 percent of virus transmission is only because of improper sterilization. The following paper proposes efficient and proven ultrasonic sterilization methods that can be preferred to ultraviolet and chemical sterilization in sterilizing not only hospital rooms but also any crowded regions like malls and schools. The Cremant's formula helps in determining the appropriate and effective sterilization ultrasonic frequency level. Using machine learning algorithms, the approximate location, and the number of droplets per second present in the room will be calculated and treated with ultrasonic waves. This demonstration is proved using micro silicon balls which are similar in properties of COVID - 19 viruses. Simulation results are displayed to show the working of the same.
