Advanced ozonation processes for water and wastewater treatment : active catalysts and combined technologies /

"Ozone has been actively and widely employed in water and wastewater treatment, but the utilization of ozone alone is insufficient for purifying and disinfecting water to the emission standard of real-world situations because of its selective oxidation behaviour. With the assistance of catalyst...
