Use The Sun To Disinfect Water – Solar Water Disinfection

Solar Water Disinfection

This is a very simple and effective solution to clean drinking water: Contaminated water is filled into transparent plastic bottles and exposed to full sunlight for six hours.
Sunlight is treating the contaminated water through two synergetic mechanisms: Radiation in the spectrum of UV-A (wavelength 320-400nm) and increased water temperature. If the water temperatures raises above 50°C, the disinfection process is three times faster.

In a survival situation, you are bound to come across discarded clear plastic bottles. This tip could come in handy. You should also carry other means to purify water for drinking.

  1. I really like what you guys are up too. This type of clever work and coverage! Keep up the superb works guys I’ve you guys to my blogroll.

  2. Yes they would work to. And you are right about the availability of discarded plastic bottles. Also, they are lighter in weight if you had to carry them in a bugout situation.

  3. Would glass mason jars work, too? I don’t like the idea of heated plastic, but don’t know if there is a particular reason it is used in the example other than the discarded bottles would be easy to obtain.
