principle of this technique is the production of ,ozone, for ,wastewater, treatment [5-6].The dose of ,ozone, applied for the treatment of ,wastewater, is in the range of (1 to 10 mg O 3 /l). This can only give a partial oxidation of the substances which can be transformed into biologically active sub-products.

For the removal of organic compounds in wastewater, ozone-based Advanced Oxidation Processes (AOP) are much more efficient than ozone alone. The addition of H2O2 or UV radiation accelerates the decomposition of ozone due to the increased rate of hydroxyl radical generation [9]. Less severe oxidation processes, like

The system ,ozone, and hydrogen peroxide was used to reclaim ,wastewater, from the secondary clarifier from a Sewage Treatment Plant (STP) of Alcalá de Henares (Madrid-Spain). The assays were performed by bubbling a gas mixture of oxygen and ,ozone,, with ~ 24 g Nm-3 of ,ozone, concentration, through a volume of ,wastewater, samples for 20 minutes at 25 ºC.
