Electro Chlorination system it mean a saltwater pool. With a salt water pool the water is run through a electronic chlorinater this is a device that separates chlorine from the salt turns it into chlorine gas which is then simultaneously dissolved into the water and never have to add chlorine.
Chlorination Process
Chlorination is used to disinfect the septic system. A liquid chlorine supply canister is hooked up to your septic system by a recalculating pipe that adds chlorine to your waste and waste water as it flows into your septic system. This is done with what is called a venturi chamber connected to the recirculation pipes. The pump keeps the chlorine circulating through with each flush or water drainage.
Chlorine
Chlorine is a component of various compounds, including table salt. It is the second most abundant halogen and 21st most abundant chemical element in Earth's crust. The great oxidizing potential of chlorine led it to its bleaching and disinfectant uses, as well as uses of an essential reagent in the chemical industry. As a common disinfectant, chlorine compounds are used in swimming pools to keep them clean and sanitary. In the upper atmosphere, chlorine-containing molecules such as chlorofluorocarbons have been implicated in ozone depletion. Elemental chlorine is extremely dangerous and poisonous for all lifeforms; however, chlorine is necessary to most forms of life, including humans, in form of chloride ions.
Chlorides
Chlorine combines with almost all elements to give chlorides. Compounds with oxygen, nitrogen, xenon, and krypton are known, but do not form by direct reaction of the elements. Chloride is one of the most common anions in nature. Hydrogen chloride and its aqueous solution, hydrochloric acid, are produced on megaton scale annually both as valued intermediates but sometimes as undesirable pollutants.
Physical characteristics
Chlorine, liquefied under a pressure of 8 bar at room temperature. The liquid column size is ca. 0.3×3 cm.
At standard temperature and pressure, two chlorine atoms form the diatomic molecule Cl2. This is a yellow-green gas that has its distinctive strong smell, the smell of bleach.The bonding between the two atoms is relatively weak (only 242.580 ± 0.004 kJ/mol), which makes the Cl2 molecule highly reactive. The boiling point at regular atmosphere is around −34 ˚C, but it can be liquefied at room temperature with pressures above 8 atmospheres.
Chemical characteristics
Along with fluorine, bromine, iodine, and astatine, chlorine is a member of the halogen series that forms the group 17. Chlorine forms compounds with almost all of the elements to give compounds that are usually called chlorides. Chlorine gas reacts with most organic compounds, and will even sluggishly support the combustion of hydrocarbons.
