Description Rampant environmental pollution is the most ubiquitous concern of current world. A sustainable panacea to
overarching contamination of water-borne pathogens demands cheap and eco-friendly oriented research. Solar
energy is effortlessly accessible in most of the weather conditions and can be used for water decontamination. In
this context, Solar Water Disinfection (SWADIS) appears to be feasible solution. Herein we are reporting newly
developed Carbon nanoparticles (CNP) which shows absorption of light in broad region extending from
Ultraviolet–Visible (UV) to Infrared Spectroscopy (IR). This CNP with pronounced photothermal effect has been
used for SWADIS. Photothermal effect of plasmonic nanomaterials has massive potential and has exploited for
disinfection of water. Moving towards practical device design we have developed an efficient CNP based
Multipurpose Solar Pasteurizer (MSP) and Nano-Solar Pasteurizer (NSP) which can efficiently perform the
SWADIS. Result shows that upon irradiation under natural solar radiation pasteurizers can thermally inactivate
the bacteria. The system proves to be able to perform 100% bacterial inactivation in sunny days. We also
conducted bacterial inactivation experiments by simulating 106 CFU mL−1 concentration of E. coli in water to
mimic field conditions. Results are evident that pasteurizers achieved 100% bacterial inactivation within period
of ˜45 min under sunlight.
