Difference between chlorination and water forcing.

Disinfection of water removes all kinds of pathogenic microorganisms from the water. It is carried out by several methods: chlorination, ozonation, fluorination and ultraviolet irradiation.

During chlorination, the required amount of chlorine is added to water, and during fluorination, respectively, fluorine is added. Fluoridation, in addition to disinfecting water, prevents tooth decay. This method of water purification is especially relevant in regions with maximum fluorine deficiency.

Definition

The main stage of water treatment - treatment water with chlorine. However, controversy regarding the safety and effectiveness of this unique septic tank has not subsided since its inception. For disinfection of water with this method, gaseous and liquid chlorine, as well as chlorine reagents, are used.

When a septic tank enters the water, a mixture of two acids is formed: hydrochloric and hypochlorous, which kill pathogenic microorganisms. However, there is evidence that chlorine agents are powerless against some parasites. Cryptosporidium and lamblia are resistant to chlorine.

For water fluorination sodium fluoride and fluorosolicylic acid are used. These substances are never formed in nature, they are synthesized during industrial production. Fluoridation of water is presented as a mass therapy aimed at preventing dental diseases and having no analogues in the history of medicine. However, it is not scientifically proven that fluoridated water strengthens teeth and bones.

Comparison

Fluoridation of water is unsafe for the human body. With prolonged consumption, fluoride accumulates in the body and provokes the emergence of a number of disorders, including osteomalacia and osteoporosis, dental diseases, cancer and Down's syndrome.

The fluorinated reagents used to disinfect water are so toxic that they are included in insecticides and rat poison. Calcium fluoride, which is a natural salt of fluorine, is non-toxic, but it does not fluoride water. However, despite this, a number of countries not only allow water fluoridation, but also require it to be done without fail. Get rid of fluorine by distillers and filter systems.

Chlorination causes turbidity of water, which disappears upon settling, gives it a characteristic odor. The chlorine concentration in water is quite high at present. Chlorine, reacting with substances dissolved in drinking water, forms compounds with carcinogenic properties.

Conclusions TheDifference.ru

  1. Water fluoridation is a process that requires precise dosage of the reagent (± 5%). Therefore, nozzles or taps are not suitable for the supply of liquid fluorinated reagents. Typically, liquid reagents are dosed using piston or diaphragm metering pumps.
  2. Chlorination is a cheap and proven method for effective disinfection of water. Its alternative, most likely, will be ultraviolet and ozonation, which are still used as an addition to chlorination and fluoridation of water.
  3. After the chlorination of the water is completed, free chlorine escapes from the water on its own. Although during floods and with an overdose of chlorine, its residual amounts are always present in the water. Therefore, chlorinated water is recommended to be defended or passed through filters. With an excess of fluorine, water is defluoridated.
