The effect of pre-treatments on atrazine removal from source water by microbubble ozonation.

Ozone-based advanced oxidation processes (AOPs) have emerged a promising avenue for water treatment, offering effective removal of micropollutants. Recent research underscores the potential of ozone microbubbles to enhance ozone mass transfer during water treatment, particularly when combined with pre-treatment steps. This study aimed to evaluate the efficacy of three different combined processes (chlorine/KMnO/PAC pre-treatment followed by ozonation) in removing atrazine, a common micropollutant from natural source water.
