Job description:

Nanofiltration (NF) and reverse osmosis (RO) technologies are widely used for drinking water production. RO membranes are applied for water desalination giving their ability to remove monovalent salts up to ~99%, while NF membranes are commonly used to remove micropollutants and treatment of natural waters contaminated by inorganics such as fluoride, nitrates and arsenic.


In treatment plants, NF/RO membranes are typically designed for continuous operation without considering water quality variations. However, in locations with extreme climate variability, NF/RO membranes can face radical variations in terms of hardness, salinity as well as the content of natural organic matter (NOM). Such variations can therefore affect the separation process, energy consumption and ultimately operational costs.


The aim of this project is to carry out experiments to evaluate the resilience of NF/RO membranes to remove inorganic water contaminants (e.g. fluoride, arsenic, nitrate) with varying water salinity, hardness and in presence of NOM. NF/RO separation mechanisms will be also investigated.
