“…Yet, the removal 51% of TOC (from initially 430 mgC/l) in UV/O 3 system allowed to remove toxic micropollutants e.g. of approximately 100% of phenols and polycyclic hydrocarbon, 23-96% for polychlorinated biphenyls and 74% of dioxins and furans (Wenzel et al 1999).…”

Landfilling of municipal waste is a major issue of the waste management system in Europe. The generated leachate must be appropriately treated before being discharged into the environment. Technologies meant for leachate treatment can be classified as follows (i) biological methods, (ii) chemical and physical methods. Here we review briefly the main processes currently used for the landfill leachates treatments.

“…ever, the load environment of marine humic acids could considered to be lowered with the ozone treatment, since the molecular weight of organic substances became very extremely low [30]. Table 2 shows the IL, TOC and T-N in the sediments before and after extraction with the humic substances from S1 and S2.…”

“…Over the last decade several studies have been conducted on the performance of hydrogen peroxide (H 2 O 2 ) and ultraviolet (UV) light in an advanced oxidation process (AOP) which has been successfully utilised for the treatment of various refractory (Doré, 1989;Sundstrom et al, 1990;Legrini et al, 1993;Sapach and Viraghan, 1998;Ho and Bolton, 1998;Von Gunten and Oliveras (1997); Shiraishi et al, 1999;Wenzel et al, 1999;Huston and Pignatello, 1999;Ince, 1999;Wang and Hong, 1999;Andreozzi et al, 2000a;Chiron et al, 2000). These previous studies have given the effect of initial H 2 O 2 concentration, initial concentration of the recalcitrant pollutants, and of time and UV light on the performance of the AOP process.…”

Factorial experiments provide a comprehensive understanding of the impact of operational variables on process performance. Utilisation of the Hadamard matrix taking into account all interaction effects, appeared to be efficient for giving a mathematical model that conformed to criteria validity. The predictions given by the factorial experiments model were confirmed by the experiments. Phenol oxidative degradation kinetics were not significantly influenced by pH or hardness of the solution to be treated, as is predicted by factorial experiments. On the other hand, initial H 2 O 2 concentration, initial phenol concentration and temperature significantly influenced the efficiency of the process. Optimal values were determined: a temperature of about 20°C and a C H2O2 /C phenol ratio of 120 (mg/mg).
