Research of the possibility of removing organic pollutants from water by membrane methods and purification of the obtained concentrate by chemical methods

Reverse osmosis (RO) and nanofiltration (NF) stand out for their versatility in terms of applicability to a wide range of contaminants, including personal care product (PCP) residues and endocrine disrupting chemicals (EDCs). The aim of the research was to analyse the efficiency of the removal of dosed PCPs and EDCs from model water with the use of RO and NF membranes. A study was also undertaken on the oxidation of the resulting concentrate after the membrane process - the efficiency of oxidation with ultraviolet-activated peracetic acid - UV/PAA system was analysed. Analysis of samples after each stage of the study showed that reverse osmosis was more effective in purifying water of EDCs than nanofiltration, while the UV/PAA oxidation system has a high potential for neutralising the concentrate formed after membrane processes, and points in the right direction for further in-depth research.
