Abstract:

Anti-fouling membranes were prepared by blending PES with amino-functionalized nanosilica and coated with composite layer of nanosilver/polyvinylalcohol layer. The membranes were characterized by scanning electron microscopy (SEM), Fourier transforms infrared (FTIR) spectrophotometer, contact angle, with membrane mechanical properties. The membranes performances were tested using synthetic solutions of whey simulating dairy wastewater as part of our selected goal of saving the environment. The results indicate that blending polyethersulfone with 1.5% amino-functionalized nano-silica provides a whey separation of 90% and permeate flux of 575 L/m2.h with a feed whey concentration of 0.8%. After coating the membrane surface by nanosilver/polyvinylalcohol layer, the permeate flux was found to decrease to 120 L/m2.h, while separation efficiency increases to reach 99% whey separation percentage. The fouling test indicates that coated membrane has antifouling behavior; moreover, it shows enhanced stability over operation hours for recorded parameters with decreased backwash rate.

Biography :

Adnan Alhathal AlAnezi completed his Chemical Engineering from Kuwait University in 2000. Later he joined Kuwait National Petroleum Company (KNPC) as a Process Engineer, where he worked on process design, monitoring and troubleshooting of assigned refinery unit and off sites. In 2003, he got a full government scholarship from the Public Authority for Applied Education and Training (PAAET) to continue his Master’s Degree in Applied Process Control at the Newcastle University. After that, he joined the College of Technological Studies as a Faculty Member in the Department of Chemical Engineering Technology. In 2009, he got another full government scholarship from the Public Authority for Applied Education and Training (PAAET) to continue his PhD in water Desalination at the University of Surrey, after which he was appointed as an Assistant Professor in the Department of Chemical Engineering Technology. His research interests focus on Water Desalination, Water, Energy, Membrane Technology and Nanotechnology.
