Interest has increased over the last several years in using different methods for treating sewage. The rapid population growth
in developing countries (Egypt, for example, with a population of more than 87 millions) has created significant sewage
disposal problems. There is therefore a growing need for sewage treatment solutions with low energy requirements and using
indigenous materials and skills. Gravel Bed Hydroponics (GBH) as a constructed wetland system for sewage treatment has
been proved effective for sewage treatment in several Egyptian villages. The system provided an excellent environment for a
wide range of species of ciliates (23 species) and these organisms were potentially very useful as biological indicators for various
saprobic conditions. Moreover, the ciliates provided excellent means for estimating the efficiency of the system for sewage
purification. Results affirmed the ability of this system to produce high quality effluent with sufficient microbial reduction to
enable the production of irrigation quality water.
Hamed A El-Serehyis a Professor of Biodiversity in aquatic ecosystems at Zoology Department, College of Science, King Saud University, Saudi Arabia and
a Professor of Oceanography at the University of Port Said, Egypt. At present he is full professor at Distinguished Scientist Fellowship Program at King Saud
University. He holds a PhD in Marine Biology from Southampton University and was a Research Fellow in molecular biology at Copenhagen University, Denmark.
He has an extensive knowledge of the wetlands of North Africa and the Middle East. As a Biodiversity & Zoogeography Researcher and has published 50 scientific
publications devoted to the taxonomy and ecology of a wide range of taxa (zooplankton, meiofaunas, brachyurans, sponges, molluscs and tunicates) and to wetland
conservation, and aquatic ecosystem health and management. Over the last 20 years, his research has focused on the
biodiversity and conservation of wetlands
with an interest in biological associations, functional ecology, and global changes, has led him to study wetlands across North Africa and the Middle East and serve
as consultant/member to several Conservation bodies (MSEA-EEAA, Egypt, Aquatic ecosystem health and management Society, Canada).
