Degradation of endocrine disruptors on an immobilized titanium dioxide photocatalyst in the presence of UV light was tested on a specially designed plug-flow reactor. The active part of this pilot plant reactor with the inner free volume of 3.5 L consisted of stainless steel annulets coated by titanium dioxide thin layers in a zig-zag arrangement. Two representative endocrine disruptors, 17-ethynyl estradiol and bisphenol A, in water solution were chosen for testing of the designed pilot plant reactor. Efficiency of the reactor was evaluated for various concentrations and flow rates. Process effectiveness and high reproducibility was also confirmed by estrogenity and toxicity tests. The designed photocatalytic treatment system was tested by purification of real waste water containing seven main endocrine disruptors and rinsed water from pharmaceutical industry. Efficiency of the photocatalytic degradation process varied between 44 – 100 % with respect to the individual endocrine disruptors and flow rates. Possible utilization of the photocatalytic reactor as the last purification unit at sewage plants was confirmed even for flow rates up to 300 L/h.
