Determination of Active Chlorine

Disinfection with chlorine is widely applied in our country. However, this process is generally perceived as a very simple process. Addition of chlorine into the water is believed to kill all microbes. However, there are large amounts of chlorine in sea water, table salt in medical waters and medical serums, but this has no disinfecting properties.

Chlorine compounds are generally used for disinfection and are not normally found in nature, but are produced by humans. Chlorine has been used for water disinfection in the form of different chemical compounds all over the world for many years. However, in recent studies, it has been understood that chlorine put into drinking water combines with nitrogenous substances such as nitrate in water to form chlorinated chemicals and cause cancer. The maximum values ​​of chlorine in water were then determined.

Chlorine is still used in disinfection processes because it kills many harmful microorganisms and is economical. However, there are many microorganisms that chlorine cannot destroy.

Chlorine ions which are not present in water under natural conditions but added to water can be measured. The value obtained in these measurements is called the amount of free chlorine. During disinfection, chlorine ion releases oxygen ions, thereby reducing the amount of free chlorine. As a result of this process, the chlorine put into the water is turned into active chlorine. Active chlorine reacts with some substances in water. In these reactions, microorganisms, organics, manganese dissolved in water and oxidable metals such as iron consume active chlorine.

How much chlorine consumes water is determined by active chlorine analysis. The important data for measuring disinfection with chlorine is not the amount of chlorine in the water, but the amount of active chlorine consumed.

According to the results of active chlorine measurement performed by authorized laboratories, it is necessary to decide the amount of chlorine to be put into the water.
