A large number of resources are dedicated to seawater desalination and will only grow as world-wide water scarcity increases. In arid areas with high temperature and salinity seawater, thermal desalination and power plants (dual-purpose/co-generation plants) are often employed for the production of power and water. In other areas, reverse osmosis is commonly employed. However, both technologies...

Seawater desalination facilities require an intake system capable of providing a reliable quantity of clean seawater with a minimum ecological impact. To meet these objectives, it is essential that a thorough assessment of site conditions be conducted. Physical characteristics, meteorological and oceanographic data, marine biology, and the potential effects of fouling, pollution, and navigation...

In this study, abstraction, desalination and recharge method and SEAWAT numerical model are used to investigate seawater intrusion repulsion in a hypothetical two-dimensional coastal aquifer to understand the relation of seawater intrusion with abstraction, desalination and recharge parameters (i.e. abstraction/recharge rate, wells distance and depth). Abstraction, desalination and recharge con...

At low pressure and temperature, water is easily vaporized under partial vacuum pressure. Desalination of seawater as source of potable water is globally considered as an applied reliable technology. At low temperature and pressure, the heat transfer process yield is higher than any normal process. Therefore, the rate of vaporization of seawater is much higher than any usual processes. The part...

In this paper, a simulation model of a spray flash desalination system is proposed. In the spray flash desalination system, the freshwater is made from the evaporation-condensation process, i.e., evaporation of warm surface seawater in a flash chamber and condensation of the generated vapor by deep cool seawater. A simulation model of the spray flash desalination system is constructed by using ...

Development of one or more large-scale seawater desalination plants in the State of Texas will provide a sustainable source of drinking water and represents a key component of alternative water resources planning for the future. Planning and implementation of a seawater desalination plant represents a significant infrastructure project and requires positive action in the areas of funding, envir...

Scientific domain: %scientific_domain Subject short description: Water shortage and decline of the quality of fresh water resources make sea water desalination become a major way for drinking water production. Reverse Osmosis (RO) is now the main technology used for seawater desalination, but it shows a limited recovery and the environmental impact of large volumes of rejected brines is still a...

Seawater desalination for agricultural irrigation will be an important contributor to satisfying growing water demands in water scarce regions. Irrigated agriculture for food production drives global water demands, which are expected to increase while available supplies are further diminished. Implementation of reverse osmosis, the current leading technology for seawater desalination, has been ...

Seawater desalination, the desalination of waters flowing back from hydraulic fracturing processes and brackish water desalination constitute important desalination applications. These have a combined market size in excess of $25 billion per annum and a combined water production rate equivalent to the domestic consumption of over 300 million people. Each application offers its own distinct chal...

Thermal desalination plants consume large quantifies of heat energy for seawater evaporation. In condensing water vapor procured in evaporators and cooling distillate, a major part of heat energy is lost in the environment. Heat energy in processes of condensation and evaporation in desalination of seawater is quantitatively equal but these processes take place under different temperatures. Dif...
