Methods to remove possible Cryptosporidium cysts using 1 micron or less filtration from drinking water.
While were at it, lets sterilize it
A Ultraviolet (UV), Counter Top, Water Purifier...
This unit uses both filtration and purification technology.
The specially-designed 0.5 micron carbon block cartridge is 99.9% effective in removing chlorine, lead, bad tastes, odors,
cryptosporidium and giardia cysts.
The UV lamp, which is enclosed in a quartz sleeve, produces ultraviolet light that destroys waterborne pathogens such as bacteria and viruses by penetrating the cell wall and deactivating the DNA so it is unable to reproduce.
The lamp uses only 10 watts and will last 9,000-10,000 hours (should be replaced annually). The transformer has an indictor light which notifies you if the lamp has burned out.
Ultraviolet water purification lamps produce UV-C or "germicidal UV," radiation of much greater intensity than sunlight. Almost all of the UV lamp's output is concentrated in the 254 nanometers (nm) region in order to take full advantage of the germicidal properties of this wavelength. Most ultraviolet purification systems are combined with various forms of filtration, as UV light is only capable of killing microorganisms such as bacteria, viruses, molds, algae, and yeast. It has absolutely no impact on chlorine, VOCs, heavy metals, and other chemical contaminants.
Nevertheless, it is probably the
most cost effective and efficient technology available to homeowners to eliminate a wide range of biological contaminants from their water supply.
Reverse osmosis, also known as hyperfiltration, is the most common treatment technology used by premium bottled water companies.
It is effective in eliminating or substantially reducing a very wide array of contaminants, and of all technologies used to treat drinking water in residential applications, it has the greatest range of contaminant removal.
Reverse osmosis will allow the removal of particles as small as individual ions.
The pores in a reverse osmosis membrane are only approximately 0.0005 micron in size (bacteria are 0.2 to 1 micron & viruses are 0.02 to 0.4 micron).
