Nano SWADIS Bottles: Boon for Remote communities

Environmental contamination is one of the most ubiquitous issues of current world and addressing the concern of waterborne pathogens calls out for cheap and ecofriendly oriented research. In this regard, solar water disinfection (SWADIS) is a clean and sustainable technology to inactivate the rapidly growing bacterial pathogens. In current work, we highlight technological developments to enhance the efficiency of SWDIS using a carbon nanoparticles (CNP) based Nano SWADIS bottles.The system was proven to be able to performed 100% bacterial inactivation in sunny days. Experiments were performed over 8 months by adding 106 CFU mL-1 concentration of Escherichia coli (E.coli) in water to mimic field conditions. The efficacy of the system was indicated by bacterial analysis (presence/absence of total coliform and faecal coliform) performed, making it appropriate for treatment of water.
