Regardless of where drinking water comes from — be it from a faucet or a well — it is not always safe to consume. Sometimes, it can contain pollutants that are harmful to living creatures. Water filtration systems are designed to address this problem because they separate the liquid from the pollutants it contains. Numerous methods have been developed to do this, however, the objective of them all is to filter dangerous components from the water. It is vital to understand how different water filters work, to select the best one for your circumstances.
Filters that are based on charcoal are the most popular type. Often, these models are called granular powered carbon filters. They are efficient, reliable and — assuming their micron level does not exceed one — they will remove most damaging pollutants, like giardia and cryptosporidium. They have a good deodorizing effect on water too. As time passes, charcoal filters become less effective, because they accumulate unwanted debris. Then, when this deteriorates, the water might taste different. These filters need to be changed frequently, to stop any nasty odors from building up.
Ceramic water filters are cartridges that fit onto bench top filters. These filters often have exterior shells made from porous ceramics, with inbuilt nano silver so that sufficient pollutants are removed, to ensure bacteriological sterility. The drawback with these systems is that their flow rate is slow, and they do not get rid of chemical pollutants.
If the analysis of water shows that it contains lead, ferrous iron, sodium, nitrates or fluoride, another type of water filter could be more effective. Normally, reverse osmosis filters can deal with such pollutants. Before buying one of these filters though, be mindful that they can waste water during the filtering process. Furthermore, they only produce a small amount of water suitable for drinking, because they filter slowly.
Water filter systems based on ultraviolet radiation use high-frequency lights to destroy living organisms inside the liquid. These systems are not common in America, however, they are often seen in the hotels of developing countries. While these systems do seem to work effectively most of the time, there’s no guarantee that they will continue to work without regular laboratory analysis.
Ramifications can arise from drinking unfiltered water. A few of the worst issues include cancer, impaired development, gastrointestinal conditions, heart disease, and even loss of life from bacterial infections. Problems that are less severe include rust stained clothes and appliances, and misty water. As well as being healthier for people to consume, filtered water normally has a nicer taste too.
