Chlorination of water: to be unsafe or why chlorinated water, chlorine can be replaced by something else

Everyone knows that the water that flows from the tap in every home, passed a preliminary chemical treatment. But the question is, as far as is necessary and right, still remains open.

Why chlorinated water

In the 1900s the first to use a chlorine compound to deliver water from the living therein harmful microorganisms. Since then, little has changed. This method is used everywhere today.

Reference! It chlorination of water in 1908 helped to cope with the cholera epidemic in Russia.

To neutralize the vital activity of bacteria and protozoa at sewage treatment plants to pick up water from natural bodies of water or added liquid chlorine bleach. They are detrimental to all "living creatures" located there. It is assumed that the chlorine standards adopted by the guest, are quite small and can not cause harm to humans. So the water is disinfected, gets normal color, smell and taste neutral.

Urban services are added chlorine compounds in abundance to all pathogenic flora and fauna has probably defused. Typically, the procedure of calculation produce at least 0.3 mg per liter of residual chlorine after half an hour after the treatment. If the index is less then the water is considered to be of poor quality. In held epidemics periods may double chlorination, then the concentration of the compounds is even higher.

Is it possible to replace chlorine with something else

In some cities (Moscow, St. Petersburg) for the purification of drinking water began to use ozonation, and ultraviolet treatment technology, and for the replacement of chlorine using sodium hypochlorite. But all this is not as effective as self chlorination. So named technologies are likely additional methods used to enhance the quality of water.

In the near future is unlikely to happen rejection of the established procedure, because:

• this is the most effective method of water disinfection of all currently known;
• not observed chlorine deficiency in the world, making it relatively cheap;
• long-standing practice of using shows all its advantages.

All of this suggests that today the replacement of chlorine water purification treatments to something else impossible and meaningless. One can only hope that in the near future, scientists invent new ways of disinfecting drinking water.

Is it safe to chlorination

Unfortunately, despite all the arguments in favor of the chlorine treatment, this water is still harmful and dangerous to humans. All the matter in the residual chlorine, which tends to accumulate in the body. Moreover, when heated (e.g., when the kettle boil) is formed an even more toxic substance - chloroform.

Even if you try not to drink untreated tap water, it still gets inside the human body through the skin. It is proved that the time spent in a warm chlorinated bath is about ten liters of water drunk. By the way, when you feel the dryness and tightness of the skin after the household hygiene - it is a manifestation of a high concentration of chlorine in the water. He has a detrimental effect on the hair (making them dry and brittle), irritating the mucous membrane of nose, throat and eyes.

As a result of years of research, scientists have concluded that there is a direct correlation between the use of chlorinated water and the development of dangerous diseases. Detrimental consequence of accumulation in the body of the substance can be a liver disease, heart and kidney failure, breast, colon, larynx. Furthermore, miscarriage in pregnant women is increased and the possibility of threat to long-term fetal abnormalities (e.g., a cleft lip or cleft palate).

What to do to reduce the chlorine content in the water

The simplest procedure - defending. Before you can use the water for other purposes, you can dial it in a separate container and let stand for about 24 hours. Then the upper half of this volume can be accurately poured into the kettle or pot for cooking, and the residue must be drained - there are all settled carcinogens.

The above method is not for everyone. To make the process faster, more convenient and easier, it is recommended to use an additional purification system. For example, carbon filters perfectly free water from all of harmful substances. They can be used as individual tanks or as a static unit directly under the sink. The only condition for their use is frequent replacement (according to the instructions, about once every one or two months).

Important! Remember that after filtering the water does not remain preservatives, so in just a day it has to be a lot of bacteria.

Now you know all about the benefits and dangers of chlorination and can make their own conclusions about how it is important to take measures to neutralize the residual connections after chlorination.
