Ferrates as a New Approach in Drinking Water Treatment

Popis výsledku v původním jazyce

Chlorination is the most used disinfection technology for drinking water treatment. Based on last research it is obvious that chlorine disinfectants are releasing harmful substances that can cause serious problems in human health. Since the discovery of harmful by products the new oxidants/disinfectants have been investigated to replace chlorination. Ferrates are a powerful oxidising agent with the strongest redox potential among all of used oxidants. These high-valent states (VI, V, IV) iron compounds can be used as green oxidants in synthetic, organic transformations, water oxidation catalysts, and efficient agents for drinking water treatment. In this study we tested commercial product ENVIFER (NANOIRON, CZ) for reduction of E. coli, faecal coliforms and cultivable microorganisms at 22 and 36 °C (European parameters legislatively observed in drinking water). The ferrates efficiency was compared with commonly used chlorination. ENVIFER in amount of 50 mg/L was much more sufficient for E. coli and microorganisms at 22 and 36 °C removal than sodium hypochlorite. Ferrates are also suitable for elimination of heavy metals (arsenic and many others) and many organic compounds. Rapid reaction with contaminants and low reagent consumption is the advantage. It can serve as an efficient alternative to sodium hypochlorite usage.
