   Where chlorine in the water come from?

   The simplest generalization, the source of chlorine in the water caused by water pollution.

   due to microbial contamination is the most common causative agent of foodborne illness. Natural water naturally contains a variety of bacteria, and then transferred through the conduit system to every household, if not sterilized, then became "inoculum", then even though they are sterilized by heating, produced by the toxin on often powerless . So, at the source to be sterilized, and the ability to inhibit the growth of bacteria in the water to keep the system, it becomes a critical aspect of safe drinking water.

   The most commonly used means of sterilization is chlorine

   Generally, the chlorine or chlorine dioxide into water to form hypochlorous acid and hypochlorite. They have superior oxidizing ability to kill many bacteria. Chlorine, chlorine dioxide, hypochlorous acid, hypochlorite, are not stable. In the light, heat and other conditions, may be further converted to the hydrochloride, hydrochloric acid, chlorine will form small amounts of other compounds.

   In the tap water will leave little hypochlorous acid and hypochlorite, which is accomplished by the bacteria. In other words, tap water requires a certain "free chlorine" exist in order to ensure the safety of tap water in the course of transmission.

   residual chlorine in water have much impact?

   over the past few decades, humans explored a variety of ways to kill the microbes in drinking water. Either way, will bring unintended consequences of sterilization - a variety of "sterilization byproduct." In 2007, the "mutation" (MutationResearch) published a review on summarized by-products in drinking water over the past 30 years in various sterilization methods produced a total of 85 kinds, however, WHO and other institutions that these sterilization by-products to give the "possible risk" than non-sterile due to the "real risk" to be several orders of magnitude.

   Chlorine dioxide is chlorine orWater sterilization program in a cost-effective. Although not as ozone so "advanced", but the advantages of efficiency and cost makes it still widely used in many parts of the world, and will have more research on its safety.

   Since sterilization can naturally have some toxicity

   A few Several epidemiological survey, it seems that high chlorine water may have an impact on health. For example, in a 1933 document, he referred to the long-term drinking water chlorine treatment may trigger asthma. In 1984 a document, referred to the chlorine and hypochlorous acid increases the risk of dermatitis. In 1987 and 1990 two papers, were also referred to the high chlorine in drinking water may have some relationship with the cholesterol and bladder cancer.

   there are some experts advise: chlorine in the water, after heating will become trihalomethanes, the presence of water vapor inside the large number of inhalation may be suffering from bladder cancer, and even face the risk of miscarriage in pregnant women.

   Therefore, more and more people are choosing to install a water purifier, home water purifier can not only trapped water pollution caused by viruses, bacteria, you can also filter out chlorine, protection of drinking water family Safety.
