dc.descriptionThe degradation of Kraft E1 pulp mill effluent was studied by four different ozonization oxidation systems (O3/pH3, O3/pH11, O3/pH11/H2O2, O3/pH11/UV). The investigation was focused on the reduction of total organic carbon (TOC), total phenols, color and acute toxicity (monitoring by inhibition of Escherichia coli respiration). For a reaction time of 90 minutes, the O3/pH11/UV was the most effective process for decoloration (45%). The O3/pH11/H2O2, O3/pH11/UV and O3/pH11 processes showed the best results for total phenols reduction (approximately/= 90%). None of the studied processes showed a significant TOC reduction. The O3/pH11/UV and O3/pH11 processes were effective for the acute toxicity reduction. Different kinetic parameters were also determined in order to quantify the reactivity of the effluent towards the applied oxidation systems.
