The subject of the work was the removal of pharmaceuticals (diclofenac and amoxicillin) by integrated methods of advanced oxidation and membrane filtration. The advanced oxidation process was carried out using UV/H₂O₂. The filtration process was carried out using two polymer membranes: HL and NF270. The efficiency of concentration reduction and COD and TOC reduction of tested solutions during UV/H₂O₂ process, nanofiltration, and in integrated method using both processes were compared. It was found that the advanced oxidation process allows a slight reduction of such parameters as COD and TOC, despite the total disappearance of the tested compounds concentration. Toxicity studies have shown that the degradation products of diclofenac and amoxicillin are toxic. The nanofiltration process allowed to almost completely remove diclofenac and amoxicillin from the solution. The integration of both methods enabled both the chemical modification of the tested compounds as well as the removal of their toxic oxidation products from the solution.
