Scientists Come Up With New Method For Water Supply Facilities Disinfection, NUST MISIS reports

"Ozon is increasingly being used for water decontamination. However, it is rarely used for surface disinfection despite its numerous technological, economic and environmental benefits," noted Valentin Romanovski, Senior Researcher at Research Center for Structural Ceramic Nanomaterials, NUST MISIS.

"Ozon is increasingly being used for water decontamination.

Scientists from NUST MISIS and KTH Royal Institute of Technology have found that the use of ozone solutions instead of chlorine-based disinfectants significantly lowers the risk of corrosion, resulting in significant reduction in the amount of iron released into tap water. Ozone treatment was proven to have the lowest negative impact on the environment and human health. Another important aspect to consider is the processing time, which in practice means a stop of the drinking water production. If it takes long time and requires handling of chemicals, flushing, and waste effluents, the surface disinfection treatment will be delayed more commonly and is less preferred. Ozone solutions require the shortest time of treatment (30 min) as compared with 6-24 hours for chlorine-based treatments.
