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.

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.

As shown in Table 2, the biodegradability of wastewater was enhanced to 0.33 after ozonation, indicating the wastewater was easily biodegraded (Lu & Wei 2011). In addition, it was found that the PS concentration and the microtoxicity decreased greatly ( Table 2 ).
