Abstract :- Providing safe drinking water is of paramount importance for sustaining life. New technology, Safe Water and Sustainable Technology Initiative from Indian Knowledgebase (SWASTIIK), combining hydrodynamic cavitation and natural oils having antimicrobial properties, was evaluated for effective water disinfection using fennel seed oil for the first time. For model organism, E. coli., while acoustic cavitation (0.2% fennel oil) gave 100% disinfection in 10 minutes, for vortex diode cavitation device, the disinfection in 2 minutes was 70% and 99.6% at 0.5 and 1 bar P respectively. Process improvement with aeration yields 100% disinfection in just 1 minute. The cost, 0.25 Rs/m3 , confirmed cost-effectiveness. The hybrid approach showed highest per-pass disinfection and high cavitational yield of 236 CFU/mL/J. The oil after the treatment can be easily separated and recycled. The removal of oil was achieved using adsorption by activated carbon to restore the original taste and smell of the drinking water
