The feasibility of effluent treatment in separate processes and in integrated systems has been compared. In the sorption process, carbon nanotubes were used in a pressure installation, enabling execution of the process of sorption with nanofiltration in a cross-flow system. Evaluation of treatment effects based on the measurement of typical pollution parameters (COD, TOC, phenolic index, forms of nitrogen and phosphorus) and concentration of bisphenol A. The results show poor feasibility of sorption as a process for advanced treatment of municipal effluent. Effluent polishing in integrated sorption-nanofiltration systems, however, guaranteed high removal rates of organic and inorganic pollutants.
