A while back I came up with the idea. It was to build a colloidal silver machine in an Altoids tin.
Well I did it and posted it here.
http://www.survivalistboards.com/showthread.php?t=100170&highlight=altoids
Now after a bunch of research I'm thinking of making a good strong batch of CS and running through my ceramic and charcoal filter several times. The silver would bind to the filter medium and keep stuff from growing there. Maybe extending the replacement period because of bacteria overgrowth.
Yes, I got my buttons pushed and went off a bit but that is maybe another thread.
Part of the deal was that some people adamantly refuse to believe colloidal silver has any medicinal value.
However
NASA,The UN,University of Utah,Johnson & Johnson even the FDA seems to think so to name a few....
Astronauts needed a way to cleanse water they take up into space, since bacteria and sickness would be highly problematic. Water filter technology had existed since the early 1950s, but NASA wanted to know how to clean water in more extreme situations and keep it clean for longer periods of time.
If you look at a water filter, you can usually detect small chunks of charcoal inside of them. Sometimes, when you first use a water filter, you'll even notice tiny black flecks from those chunks. This charcoal is specially activated and contains silver ions that neutralize pathogens in the water. Along with killing bacteria in the water, the filters also prevent further bacterial growth. Companies have borrowed from this same technology to bring us the water filter systems millions of people use at home every day.

In the 1960s, NASA’s Manned Space Center (now known
as Johnson Space Center) and the Garrett Corporation,
Air Research Division, conducted a research program to
develop a small, lightweight water purifier for the Apollo
spacecraft that would require minimal power and would
not need to be monitored around-the-clock by astronauts
in orbit. The 9-ounce purifier, slightly larger than
a cigarette pack and completely chlorine-free, dispensed
silver ions into the spacecraft’s water supply to successfully
kill off bacteria. A NASA Technical Brief released around
the time of the research reported that the silver ions did not
“impart an unpleasant taste to the water.”

Even works on some viruses
Silver has a particularly high
affinity for sulfhydryl groups on bacterial cell membranes. By binding to sulfhydryl
groups on cell walls, bacterial respiration is prevented. Since protein denaturation of
viruses is more difficult than sulfhydryl oxidation, the virucidal effects of silver are
limited.
The United Nations Environment Program (2004) has
listed silver-treated ceramic water filters as an appropriate technology for water
purifications in developing countries and regions affected by natural disaster.

The sensor detects if the drinking water contains enough iodine (used on U.S. spacecraft) or silver (used by the Russians) to kill any microbes. The International Space Station has both kinds of water purification systems.

In this paper, we fabricated silver-coated polyurethane foams and used it as a bacterial filter for contaminated drinking water. Flexible PU foams were soaked in silver colloidal solutions for 10 h, then washed and air-dried at room temperature. The prepared silver colloidal solutions and silver-coated PU materials were characterized by several techniques including TEM, FESEM/EDS, UV-VIS, ICP-AAS, and Raman spectroscopy. The TEM images showed that the size of silver nanoparticles in colloidal solutions varies from 6 to 12nm. The Raman, FE-SEM/EDS and ICP-AAS data illustrated that silver nanoparticles were stable on the PU foam and were not washed away by water. Furthermore, the microbiological tests (tube tests and flow test) were carried out on silver-coated PU materials with the Coliforms, E. coli, and B. subtilis. The obtained results showed that the bacteria was killed completely with antibacterial efficiency of 100% being observed. Our research suggests that silver-coated polyurethane foams can be used as excellent antibacterial water filters and would have several applications in other sectors.

New protocol to reduce MRSA using antimicrobial wound dressing ACTISORB* Silver 220
ACTISORB* Silver 220 is clinically proven to manage bacterial infection and critically colonized wounds6. This silver charcoal dressing adsorbs toxins and other agents, which have an inhibitory effect on wound healing7. Its broad-spectrum antimicrobial activity is effective against 151 bacterial pathogens, including MRSA8. It has been shown in PEG sites to visibly reduce infection, MRSA colonisation and overgranulation of wound tissue2.
The antibacterial properties of silver have been known and applied for centuries. The large body of research shows that it produces structural changes in bacterial cells and interacts with DNA to inactivate bacteria.

Could a dressing help in superbug fight?
An Austrian doctor believes a dressing containing silver can virtually eradicate the cross infection of MRSA in hospitals. But can this dressing, which is already used in the UK to treat burns victims, really have an impact on the NHS, where the so-called superbug is wreaking havoc? But a dressing, laced with silver, may well prove the best weapon in the fight against MRSA (methicillin-resistant staphylococcus...
