Carbon Water Filters
These systems are easy to install, relatively inexpensive, and cover the basic functions of filtration. Water filter charcoal medium carbon is derived from coconut husk. This absorbs impurities as the water passes through. This form of filter comprises possibly 95% of those in use domestically. They are simple to install, relatively economical, and depending on micron level, will filter out the most deadly of contaminants, Cryptosporidium and Giardia.
Charcoal water filters come in various forms. Carbon Block is a solidified form of honeycombed carbon. It is the best form of filter but flow rate is significantly slower than with loose charcoal. Activated Silver Impregnated Charcoal, sometimes called Chlorgon, adds chloramines exclusion and bacteria killing ability to the basic carbon.
Carbon filters cannot change the pH balance of the water. If you have acidic water, you will still have acidic water, as the minerals causing the acidity will be dissolved and therefore will pass through the carbon filter.
Reverse osmosis systems
Originally developed to process water in submarines, the reverse osmosis process basically draws water through an extremely fine membrane. The membrane acts as a very fine filter to create drinkable water from salty (or otherwise contaminated) water. The contaminated water is put on one side of the membrane and pressure is applied to stop, and then reverse, the osmotic process. It is a slow process but the result is extremely finely filtered water.
Ultra violet radiation systems
UV systems use high frequency light to irradiate water through a glass element. Water passing the element is exposed to the light, which kills all living organisms.
UV systems are very common in Third world hotels where the possibility of serious disease occurring from local water consumption is high. Although an excellent sterilizing system is always working without a laboratory analysis of the output water and sophisticated systems incorporate an hour counter, so a new element can be replaced at a safe interval.
