Solar water disinfection, in short SODIS, is a type of portable water purification that uses solar energy to make biologically-contaminated (e.g. bacteria, viruses, protozoa and worms) water safe to drink. Water contaminated with non-biological agents such as toxic chemicals or heavy metals require additional steps to make the water safe to drink.

[5] [6] Halazone tablets were commonly used during World War II by U.S. soldiers for portable water purification, even being included in accessory packs for C-rations until 1945.
Likewise, the irradiance depends on the brightness (radiant intensity, W/sr) of the UV source, the distance between the UV source and the microbe, the attenuation of filters (e.g. fouled glass) in the light path, the attenuation of the medium (e.g. microbes in turbid water), the presence of particles or objects that can shield the microbes from ...
Therefore, reliable access to clean drinking water and sanitation is the main method to prevent waterborne diseases. [ 4 ] Microorganisms causing diseases that characteristically are waterborne prominently include protozoa and bacteria , many of which are intestinal parasites , or invade the tissues or circulatory system through walls of the ...
Experiment with drinking it ice-cold or adding sliced fruit to give it flavor. Use smaller water bottles and refill them instead of filling a huge jug for the whole day, which can feel daunting to ...
