matrix and the ammonium generated by the degradation of wastewater (approximately
4 mM), fulfill the C and N, P requirements (8-10 mg/L depending on wastewater com-
position). Figure 12.4.3 shows TOC and nitrogen concentrations in the photo-Fenton
and IBR. It should be observed that the water was transferred from photo-Fenton
to biotreatment at around 200 mg/L and that it fell to around 30 mg/L very quickly (48
hours) compared to the Z-W test, demonstrating that an adapted bioreactor produces
more efficient results than the Z-W test carried out with fresh biomass. Nitrification
was also complete. In this case the combined AOP/biological process strategy can
be applied.
