Biography
Abushaban completed his MSc in Municipal water and infrastructure at UNSECO-IHE, Netherlands. He is currently finalizing his PhD at Delft University of Technology, in which his research focused on development of methods to control biofouling and scaling of reverse osmosis (RO) and ultrafiltration membrane systems. His work included bench-scale, pilot-scale and even full-scale plants. Abushaban has extensive experience in assessing and troubleshooting the pre-treatment and membrane filtration performance of full-scale seawater/industrial treatment plants. Abushaban was awarded the innovation prize of the international desalination association (IDA) in 2017. Furthermore, Abushaban has worked as water and wastewater consultant engineer, in which he managed designing and rehabilitation of several water supply and sanitation projects in Palestine.
