kloorijäämiksi

Kloorijäämiksi refers to residual chlorine compounds that remain in water after disinfection. Chlorine is commonly used as a disinfectant in municipal water supplies to kill harmful microorganisms. While effective, a portion of the chlorine can react with organic matter present in the water to form disinfection byproducts (DBPs).

The most common types of DBPs include trihalomethanes (THMs) and haloacetic acids (HAAs). These compounds are formed through a chemical reaction between chlorine and naturally occurring organic substances, such as decaying plant material. The concentration of DBPs can vary depending on factors like water temperature, pH, contact time, and the amount of organic matter present.

Regulatory bodies, such as the World Health Organization and national environmental agencies, set maximum contaminant levels for DBPs in drinking water to protect public health. These limits are based on extensive research into the potential health effects of long-term exposure. While some DBPs have been linked to potential health risks at high concentrations, the levels typically found in treated tap water are generally considered safe.

Monitoring and controlling DBPs is an important aspect of water treatment. Water utilities employ various strategies to minimize their formation, including optimizing chlorination processes and removing organic precursors before disinfection. Treatment methods like activated carbon filtration can also help reduce the levels of DBPs in drinking water.
