Unless you are fortunate enough to live on a water abundant world (like Earth, the red planet, and yes, even the Moon), future space travelers are going to have to recycle every drop of water that exits their body (regardless of origin).

Since bacteria have a tendency to thrive in micro gravity, astronauts will need to find a way to kill off these microscopic creatures before they kill us off via recycled sweat and other bodily fluids (especially since our immune system becomes weaker in zero-G).

Fortunately for us a company may have a quick solution that is not only effective but inexpensive as well.

(Homedics, note: PDF file) UVC [ultraviolet C] light, with wavelengths between 100 and 280 nm, is commonly referred to as “germicidal light” due to its effectiveness in destroying microorganisms. UVC light acts as a natural outdoor air purification system by deactivating the DNA of microorganisms and destroying their ability to multiply. […]

Utilizing the germ-killing benefits of UVC light, HoMedics, the leader in health and wellness products, developed Restore®, a complete water purification system in an easy to use pitcher. Restore combines UV Clean technology to remove bacteria, viruses and microbial cysts with a filtration system to reduce heavy metals, chlorine (taste and odor), and some industrial and agricultural pollutants.

Although this technology could also be used for off world settlers (who may have to drink recycled water until they can melt enough space ice), this technology would also benefit residents of orbital space stations around Earth, Venus or even a gas giant.

It could also help reduce the overall cost of filtering space water, allowing corporations and governments alike to invest money into other area’s (like propulsion or food).
