jäännöskloori

Jäännöskloori, also known as residual chlorine, refers to the amount of free chlorine that remains in water after disinfection. It is a critical parameter in water treatment and distribution systems, ensuring the safety of drinking water by inhibiting the growth of bacteria, viruses, and other microorganisms. Residual chlorine is typically measured in parts per million (ppm) and is maintained within a specific range to balance disinfection effectiveness and potential health risks.

The primary sources of residual chlorine in water are the addition of chlorine or chloramines during the treatment process. Chlorine is a strong oxidizing agent that reacts with organic matter and microorganisms, forming chloramines, which are less potent but more stable disinfectants. The residual chlorine level is carefully monitored to ensure it remains within the recommended range, usually between 0.2 and 1.0 ppm, depending on the specific water treatment guidelines and local regulations.

Excessive residual chlorine can cause adverse health effects, such as irritation of the eyes, nose, and throat, as well as potential damage to aquatic life. Therefore, it is crucial to maintain an optimal residual chlorine level to ensure both public health and environmental safety. Regular monitoring and adjustment of residual chlorine levels are essential practices in water treatment facilities to achieve this balance.
