Executive Summary : | Clean drinking water is a growing concern globally, with 80% of diseases caused by waterborne pathogens like bacteria. To meet specific physical, chemical, and microbiological properties, water must undergo purification stages such as primary sedimentation and filtering, ion exchange, carbon adsorption, membrane processes, chlorination disinfection, ozonation, and ultraviolet radiation. However, existing disinfection techniques have disadvantages such as the formation of carcinogenic by-products, taste, and odour, making water inadequate for drinking purposes. The present proposal aims to mitigate these issues by designing a laboratory-scale hybrid hydrodynamic combined with acoustic cavitation water treatment facility. Hydrodynamic cavitation assisted with acoustic cavitation in the flow field has the potential to generate enough hydroxyl radicals, which can be utilized for water purification. The main objectives of this research include developing a laboratory-scale novel hydrodynamic assisted with acoustic cavitation water treatment facility, operating the facility to characterize the hybrid technique, and utilizing the proposed test facility for observation and characterization of different cavitation-based approaches to water treatment mechanisms. To the best of our knowledge, no existing stand-alone facility exists to bring out the combined effects of hydrodynamic cavitation and acoustic cavitation water treatment. The proposed test facility can be utilized for observation and characterization of different cavitation-based approaches to water treatment mechanisms. |
