Submit Manuscript | http://medcraveonline.com Reverse osmosis (RO) membranes are commonly used for sea water desalination to produce fresh water. These membranes are usually prepared using interfacial polymerization. Hydrophobic diamine and water-soluble chloride salt precursor are reacted to form a thin polyamide (PA) separation layer on a porous support [1]. The PA cross-linking density has a...

The ENERCON Desalination Department has developed a new energy recovery system for RO desalination plants, optimized for the combination with wind energy converters. The main problem for the combination of desalination processes and wind energy is the fluctuation of power supply generated through renewable energies. Conventional desalination plants (and the belonging energy recovery systems) wo...

The origin and continuation of mankind is based on water. Water is one of the most abundant resources on earth, covering three-fourths of the planet’s surface. However, about 97% of the earth’s water is salt water in the oceans, and a tiny 3% is fresh water. This small percentage of the earth’s water—which supplies most of human and animal needs—exists in ground water, lakes and rivers. The onl...

Throughout the world, there are regions of vast extent that have many favorable features, but whose development is principally limited by the lack of fresh water. In arid areas where large-scale development has already occurred, e.g. parts of the Middle East and North Africa, the extraction of fresh water via desalination plants requires very large energy consumption. This motivates the develop...

Water is the most common substance in the world, however, 97% is seawater and only 3% is fresh water. The availability of water for human consumption is decreasing due to increasing the environmental pollution. According to the World Health Organisation (WHO), about 2.4 billion people do not have access to basic sanitation facilities, and more than one billion people do not have access to safe ...

Reliable production of freshwater and energy is vital for tackling two the most critical issues world facing today: climate change sustainable development. In this light, a comprehensive review performed on foremost renewable energy-driven polygeneration systems using thermal membrane desalination. Thus, designed to outline latest developments integrated desalination based multi-stage flash (MS...

The paper presents an overview of environmental issues that may be expected with nuclear desalination. The analysis of coupling nuclear power with desalination plants indicates that adverse marine impacts can be mitigated with alternative intake designs or cooling systems. The atmospheric impact of desalination may be greatly reduced through the coupling with nuclear power, while maximizing the...
