Description

Ozonation is a promising treatment step for water reuse. Compared to the “gold standard” with reverse osmosis and advanced oxidation, ozone requires less energy and does not result in a waste brine. This makes ozone more cost-effective. However, the formation of nitrosamines may be a significant barrier to the use of ozonation in water reuse applications, particularly for potable reuse.

New N-nitrosodimethylamine (NDMA) precursors that react with ozone: Implications for water reuse
