Treating Bacteria in Water with Activated Carbon Filters

You will find hundreds and maybe thousands of microorganism varieties that people face within day-to-day activities. The majority are safe, a number of them are advantageous however others are fatal. in the early 1920s, the main bacteria worry was bacillus, that causes typhoid, more of late, E.coli as well as cryptosporidium have got notoriety.

These two microorganisms originate from human and animal waste materials and in some cases can be fatal to individuals with weak natural defences, in addition to youngsters and senior citizens. These two microorganisms have already been discovered within our drinking water supplies. In the early 90’s cryptosporidium was discovered within drinking water in milwaukee and triggered health issues to almost half a million residents, along with an estimated 100 fatalities.

Even though city and county drinking water supply companies pay great attention towards the treatment of water, additional precautions are a significant technique to safeguard from damaging bacteria along with other possibly damaging chemical substances found within drinking water supplies. For this reason the point-of-use water filter industry is continuing to grow into a massive industry.

Activated carbon, due to the fact that it has a very large surface area, is among the most widely used medias within these types of filters and treats an array of organics found in water by way of surface adsorption. To stop bacteria development within Point of use filters silver ions are used to impregnate the carbon filters. Silver is widely used as a method to prevent bacterial development. Although small amounts of silver is used in this method, questions remain about silvers ability to leach into water.

Presently there is increased attention on nanosilver products that are being employed within carbon filtration. Scientific research has proven that nanosilver is actually toxic and may trigger damage in completely new ways.

Currently there are studies being performed on silver impregnated carbon in the treatment of bacterial growth. In February 1992, it was determined that following a months usage, the silver impregnated activated carbon filter had virtually lost all of its effects on barring bacterial development.

With the issues associated with how effectively silver impregnated carbons work, combined with the increase in the cost of silver, new antimicrobial materials are appearing as a less hazardous, more efficient alternative.
