Abstract
Abstract The unrestricted access to clean and inexpensive water is perceived as one of the most basic humanitarian objectives; however, it still remains a challenge in 21st century due to many factors such as constantly increasing pollution of surface water. One of the remedies for this situation might be so called in-depth municipal waste water treatment. The objective of this paper was to examine the efficacy of the pressure-driven membrane filtration (ultra- and nanofiltration) to remove bisphenol A from a variety of environmental matrices including real effluent from municipal wastewater treatment plants. The process of pressure-driven membrane filtration was realized through dead-end flow filtration with the use of different commercial membranes. It has been proved that bisphenol A retention coefficient depended both on the process type and the physical and chemical properties of the membrane applied. The type of water matrix was also significant. It has been determined that efficient bisphenol A removal is possible only in the process of nanofiltration. However, in this case the selection of an appropriate membrane is of a great importance because of the physical and chemical parameters that determine both separation properties and the intensity of adverse reactions that accompany pressure-driven filtration processes.

Summary
Water is one of the basic raw materials that support life on Earth. The unrestricted access to clean and inexpensive water is perceived as one of the most basic humanitarian objectives; it still remains the challenge of 21st century due to many factors such as constantly increasing pollution of surface water. The design process and utilisation of water stream treatment stations that use these pressure driven separation techniques becomes complex because of pollutants adsorbed on membranes after the filtration They significantly reduce the membrane working time. Based on the information presented above, this paper describes an attempt undertaken to establish the efficacy of low and high pressure membrane filtration to remove bisphenol A (an organic compound from the phenols group used in the production of plastic formulations) from different water matrices. Both a simulated and real effluent was investigated. These membranes were selected in such a way as to vary against selected physical and chemical properties
