45、mative) General information on chlorine A.1 Origin A.1.1 Raw materials Chlorine is manufactured from a sodium chloride solution. A.1.2 Manufacturing process Electrolysis of alkaline metal chlorides (generally in the form of a solution). A.2 Use A.2.1 Function Disinfectant, oxidizing polluting matter

46、 introduced to the pool water by bathers. A.2.2 Form in which the product is used It is used as delivered (see A.2.4). A.2.3 Treatment dose The treatment dose depends on the composition of swimming pool water, subject to national regulations and depending on the required free chlorine concentration

47、in the swimming pool water. A.2.4 Means of application Only vacuum chlorinators should be used and a separate chlorine-gas room having special fittings will always have to be provided for safety reasons. An automatic chlorine cylinder switchover system should be provided to prevent any interruption

48、in the chlorination (in particular due to chlorine cylinders becoming empty). As a result of adding chlorine gas, hydrochloric acid is formed in the water and the resulting acidity causes a drop in the pH value. To avoid any undesirable drop in this value if the acidity is low, the chlorine solution

49、 may be fed through a reaction vessel filled with calcium carbonate (e.g. high-purity marble or Jurassic limestone). A.2.5 Secondary effects The secondary effects include the following: decrease in pH due to generation of hydrochloric acid; formation of chloramines (combined chlorine) and organo-chlorinated by-products such as trihalomethanes, depending on swimming pool water quality. A.2.6 Removal of excess product The most practical method is the use of a reducing agent such as an aqueous solution of a sulfite compound. Ot
