Professor Nidal Hilal
The PhysOrg article Bacteria and nanofilters — the future of clean water technology said
Bacteria often get bad press, with those found in water often linked to illness and disease. But researchers at The University of Nottingham are using these tiny organisms alongside the very latest membrane filtration techniques to improve and refine water cleaning technology. These one-celled organisms eat the contaminants present in water — whether it is being treated prior to industrial use or even for drinking — in a process called bioremediation.
The water is then filtered through porous membranes, which function like a sieve. However, the holes in these sieves are microscopic, and some are so small they can only be seen at the nanoscale. Pore size in these filters can range from ten microns — ten thousandths of a millimeter — to one nanometer — a millionth of a millimeter.
These technologies can be developed into processes which optimize the use of water — whether in an industrial system or to provide drinking water in areas where it is a scarce resource.
The research is led by Nidal Hilal, Professor of Chemical and Process Engineering in the Centre for Clean Water Technologies — a world-leading research centre developing advanced technologies in water treatment.
Nidal Hilal, BEng (Homs), MSc (Wales), PhD (Wales), DSc (Wales), Eur
Ing,
CEng, FIChemE is Professor of Nano-membranology and Water
Technologies, School of Engineering, Swansea University, UK.
Nidal’s current research activity focuses on water treatment, novel
membrane separation processes, membrane nanotechnology, and the
application of atomic force microscopy (AFM) to chemical and process
engineering. He is now internationally recognized as a world-leader in
developing and applying the force measurement capability of AFM to the
study of membrane surfaces.
His research has produced several breakthrough innovations, including
the development of novel membranes; the smallest AFM colloid probe
reported in the literature; the first AFM coated colloid probe
technique; the first AFM cell probe technique; the first direct
measurements of the interaction of single live cells with surfaces; the
first use of the atomic force microscope in meso-scale cavitation
studies. His most recent scientific breakthrough has been the
development of a ground-breaking AFM-HSMP technique that combines AFM
force-distance measurements with ultra-high speed micrography to study
rheology and extensional fluid properties. All these
techniques/technologies have widespread applications in process
optimization and the development of novel processes.
He has also been highly active in finding multidisciplinary,
collaborative applications of atomic force microscopy and process
engineering. For example, current projects range from rheology of
colloidal suspensions and superspreading with nano-scale interactions to
fabrication of re-usable materials based on mineral particulates. This
approach has been highly successful in attracting both significant
funding from EPSRC and industrial interest.
Nidal has published around 200 articles in the refereed
scientific literature. His work has also been published widely in highly
reputable journals, refereed international conference proceedings, and
invited book chapters. The coauthors on many of his publications
reflect the strong international links which he has established.

Nidal has been the co-chairman of a pioneering international
research event at the University of Oxford on Water and Membranes. He
has also been invited to act as a member of the scientific committees in
international conferences and delivered a numerous number of invited
lectures around the world. He has made major contributions to discussion
panels on global water issues and desalination for a number of science
programmes including
Home Planet and
The Material World for BBC
radio 4.
He is also a member of editorial board for the
Desalination journal, a
member of the project advisory board of the Middle East Desalination
Centre, on the panel of referees for the Research Councils in the UK,
Canada, Finland, and Norway and for more than 40 international journals.
Nidal has been the Director of the
Centre for Clean Water
Technologies in SChEME since 2003. This centre is internationally
recognized for research into potable and waste-water treatment
technologies, including desalination, advanced oxidation, membranes, and
colloid and interface-based technologies.
He has been awarded the
Doctor of Science Degree (DSc) from the
University of Wales in 2005, in recognition of an outstanding research
contribution in the field of Scanning Probe Microscopy and Membrane
Science and Technology.
The world-leading reputation for research that Nidal has
earned in the fields of membrane technology and water treatment have now
been formally recognized by the award of the prestigious
Kuwait Prize of
Applied Science for Water Resources Development for the year 2005.
This
has been awarded by the Kuwait Foundation for the Advancement of
Sciences (KFAS). This prize is one of the highest scientific honors
which are awarded in the Middle East for intellectual achievement. This
is the first time that the award has been made to an academic in a UK
university.
Nidal earned his DSc, PhD, and Masters degrees in Chemical Engineering
from the University of Wales, UK and his Bachelors degree in Chemical
Engineering
at Homs, Syria. He is a Chartered Engineer, a Fellow of the Institute of
Chemical Engineers, a member of the European Desalination Society and a member
of the European Membrane Society.
