Adoption of the Water Framework Directive (Directive 2000/60/EC) provides a policy tool enabling sustainable protection of
water resources. The main aim of our research acitivities is to find the most appropriate technique for the removal of priority
and relevant substances from water using ozone based reactions, designing controlled oxidation processes and eventually also an
ozonation reactor. The aim of this presentation is to summarize the main results of ozone application to degrade BT and 2-MBT from
model wastewater with selected ozone based processes (O3, O3/ZEO, O3/GAC). Benzothiazole (BT) and its derivates are widely
used, mainly as herbicides and fungicides, anti-fungal drugs, corrosion inhibitors in cooling water, slimicides in the paper and pulp
industry and largely as vulcanization accelerators in rubber production. They are toxic and poorly biodegradable. Benzothiazoles
(BTs) have been detected in the environment for instance in wastewaters, soils, estuarine sediments, and superficial waters. Our
results of ozone utilization for wastewater pretreatment indicates that 99% of BT were removed after 80 minutes of ozonation.
Efficiency of BT mineralization was increased three times using the O3/GAC process compared with ozonation only. The 2-MBT
removal rate was three times higher than that of BT wastewater. Efficiency of BT removal was lower by 31% in wastewater containing
2-MBT. The results of ozonation of wastewater containing BT and 2-MBT simulating real industrial wastewater prior to the biological
treatment indicate the feasibility of this procedure. This work was supported by the Slovak Research and Development Agency under
the contract No. APVV-0656-12. The authors would like to thank also for the support from the VEGA Grant 1/0859/14.
