Development of novel nanofiltration (NF) membranes for selective separation between organics and inorganics

Short CV / biography:

After my bachelor in science in chemical engineering in Iran, I finished my master in science in chemical and process engineering at the university of Bologna, Italy. I did my master thesis on ”phosphate removal of wastewater by ion exchange membrane: a numerical and experimental study” at the Delft university of technology. I am familiar with different separation processes. In my spare time, I like reading books, playing football and hanging out with friends.

Short description of my topic:

Forward Osmosis (FO) process in water and wastewater treatment has been attracted a huge attention recently, mainly due to its low energy consumption. The distinguishing feature of FO compared to other membrane-based filtrations is the use of osmotic pressure difference as the main driving force for water permeation through a semi-permeable membrane. FO performances heavily depend on membrane (bio)fouling and scaling. Cell geometry, feed and product spacers, type of draw solute and other operation conditions could significantly affect (bio)fouling and scaling behaviour. Due to complexity of system, containing different types of fouling, a numerical model is necessary in order to recognize the quantitative effect of different parameters on the membrane performance. The aim of this project is to implement the numerical models to simulate and predict (bio)fouling behaviour and effect of different parameters on FO performance.
