Book Description
1.1 Background Water–stress is becoming one of the greatest challenges of the 21st century. The fast growth of population, tourism, and agriculture development in the world has resulted in a great demand for access to clean water [3]. Most of the developing regions of the world are still suffering from water scarcity. The problem of water shortage is being extended to other nations of the world. The lack of access to safe drinking water poses significant problems globally. Fresh water is not available for around 1.2 billion people worldwide while around 2.6 billion may obtain limited or unsafe water. This may be the result of climate change with extreme industrial and agriculture activities. It was assumed that by 2025, two thirds of people around the world will be living in water-stressed countries [4]. Thus, the requirement of potable water to sustain human life in the world will rise from 4500 billion m3 to 6900 billion m3 by 2030 which goes beyond the accessible water resources [5]. Therefore, we need to meet and sustain these growing demands as soon as possible. A promising technology to meet the demand of fresh water is water desalination using membrane technology. A recent study reported that the daily production of desalinated water was up to 25 million m3 globally [6, 7]. Water desalination was developed to remove salts and other contaminants from seawater, brackish water and produced water to acquire drinking water [8]. Singh et al. [9] stated that since 1995 membrane filtration has been effective in removing microbiological species such as Giardia and Cryptosporidium. It has also been reported that membrane-based desalination provides 63.7% drinking water while thermal desalination method provides almost half of it, about 34.2% globally [10]. For instance, micro-filtration and ultrafiltration membranes can reject particles much smaller than 1 micron such as proteins, oil droplets, bacteria, etc. In contrast, Nano filtration and reverse osmosis can separate particles in the range of 1/100th to 1/1000th of a micrometre, such as aqueous salts, sugars, and amino acids [11]. Among the membrane desalination technologies, reverse osmosis (RO) is being actively used in most countries due to their significant properties and ease of obtaining drinking water.

Book Description
This book investigates the need for a more open and interdisciplinary dialogue on the nexus of food, water and energy security in the Arab region. It argues that achieving sustainable economic development is irretrievably tied to the security of the water–energy–food nexus, which is in turn essential for bringing about sustained peace. Further, it discusses various approaches to achieving these lofty objectives, and offers the following take-away messages: The Arab region is currently under considerable water stress, and the situation will continue to get worse with a number of global changes – most notably those related to climate and regional water distribution. Viable solutions are available in the Arab region and can be implemented through innovative policies, judicious use of new technologies, and stimulating public opinion. Integration across water, energy, and food sectors is obviously needed but achieving it in practice is extremely challenging. There are some gaps in the scientific understanding but at the same time there is a wealth of data and synthesized information that can guide decision-making.

Book Description
Forward osmosis (FO) is an emerging membrane technology with a range of possible water treatment applications (desalination and wastewater treatment and recovery). Recent Developments in Forward Osmosis Processes provides an overview of applications, advantages, challenges, costs and current knowledge gaps. Commercial technology, hybrid FO systems for both desalination and water recovery applications have shown to have higher capital cost compared to conventional technologies. Nevertheless, due to the demonstrated lower operational costs of hybrid FO systems, the unit cost for each m3 of fresh water produced with the FO system are lower than conventional desalination/water recovery technologies (i.e. ultrafiltration/RO systems). There are key benefits of using FO hybrid systems compared to RO: • chemical storage and feed systems may be reduced for capital, operational and maintenance cost savings, • reduced process piping costs, • more flexible treatment units, • higher overall sustainability of the desalination process, while producing high quality water.
