Disinfectants like chlorine- or bromine-based reagents, ozone, and organic substances are used depending on the application. Chlorine-based reagents are used in over 90% of disinfection applications, including cooling water, bottle cleaning, cold CIP, wastewater from treatment plants, and swimming pools.
Drinking water treatment
An example from Germany shows the drinking water treatment for about 4 million people. Water is abstracted from Lake Constance, cleaned of algae and suspended solids, and then disinfected. Ozone is often used as a disinfectant, followed by flocculants and multilayer filters. Before distribution, the water is slightly chlorinated to ensure safe supply.
Online measurement of disinfectants
Accurate dosing of disinfectants is crucial to avoid over- or under-dosing. Online measurement systems enable automatic dosing and provide full documentation of measured values. This significantly improves process safety and water quality.
Different chlorine compounds
Depending on the country and distribution network, free chlorine, chlorine dioxide, or bound chlorine is used. Free chlorine is pH-dependent and requires a combination of chlorine and pH measurement. Chlorine dioxide is pH-independent and increasingly used. Bound chlorine offers long-lasting disinfection, ideal for long distribution networks.
