As cleaning the aqueous phase is only possible in summer, this work focuses on the impact of biofouling on the efficiency of filtration membranes. In the initial stage of the study, the selection of a membrane with minimal cell adhesion was conducted.

Periodic washing of the membrane with dilute nitric acid ensures a constant filtration rate during long-term operation. Given the low retention capacity of the NF membrane for nitrate ions, the possibility of their biological removal via a mechanical filter containing microbial biofilms has been demonstrated.
