Quality Water Filters 4 You Posting Page
Monday, January 7, 2013
Water chlorination is carried out in most municipalities around the planet today, as a cheap and effective way to prevent the spread of disease. Overall, the effect is positive – our cities are crowded as never before in history, yet they are no longer swept by cholera, dysentery, and typhoid fever which killed millions of our ancestors.
In fact, the use of chlorine as a city water disinfectant leads to the question of whether it is necessary to filter your water at all in metropolises where it is present in the water supply. After all, someone might reason, if the utility company is putting chlorine in to make the water safe to drink, what more is needed to keep me safe?
To some degree, this is true. Chlorine does effectively kill a whole range of extremely nasty bacteria which would otherwise be very dangerous to anyone drinking the water. It does so thoroughly and reliably, making the water far safer than the drinking water available to humans through most of time. If you smell chlorine in the water, you know that you're not going to come down with cholera or any of the other deadly digestive bacteria mentioned above.
However, there is also a lot that chlorination can't do. Just because it kills a wide range of microorganisms doesn't mean that the water is completely clean after that. It can't actually remove anything from the water, such as chemicals or even particles of sand. All of these can degrade water quality, even if they are far less immediately hazardous than bacteria, so depending on local water conditions, a filter may still be needed.
