Abstract
Availability of clean drinking water is an ongoing global demand. Contaminated water sources, inappropriate waste disposal, and inadequate hygiene procedures exacerbate it. These elements support the growth of pathogenic microbes like bacteria, viruses, and parasites, which cause a variety of diseases that are transmitted by water. Disinfection plays a vital role in water treatment processes by eliminating these pathogens and ensuring public health safety. Commonly used methods like Chlorination, Ozonation, and Ultraviolet (UV) treatment are well known for their effectiveness in disinfection. However, chemical disinfection methods have drawbacks, including the potential formation of carcinogenic residues. The efficacy of disinfection techniques varies based on factors such as water quality conditions and the resistance of microorganisms to treatment. Consequently, there is increasing interest in alternative disinfection approaches that reduce reliance on chemical agents. The potential of hydrodynamic cavitation as a cutting-edge method for water disinfection is examined in this review paper. Hydrodynamic cavitation shows significance in reducing levels of microorganisms such as Total Coliforms and E. coli. A method for successfully eliminating pathogens from water is provided by the physical and chemical effects produced by cavitation bubbles. Furthermore, the review examines critical variables such as pressure, temperature, pH levels, and the design of cavitation devices, all of which significantly impact disinfection efficiency. Developing sustainable and efficient water treatment systems requires an understanding of and optimization of these parameters. By advancing alternative disinfection technologies like hydrodynamic cavitation, researchers aim to address current challenges in water sanitation effectively. These innovations not only improve water quality and public health but also mitigate environmental impacts associated with traditional chemical disinfection methods.
