Desalination was for long considered a technology too expensive to adopt in most arid countries except those with large reserves of fossil fuels and affluent economies. Recent advances in desalination technology have abolished this old paradigm and have increased its market share in many arid and semi-arid countries. Nevertheless, the introduction of a desalination plant will inevitably be asso...

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...

Large-scale desalination plants are complex systems with many inter-disciplinary interactions and different levels of subsystem hierarchy. Advanced complex systems design tools have been shown to have a positive impact on design in aerospace and automotive, but have generally not been used in the design of water systems. This work presents a multi-disciplinary design optimization approach to de...

behaviour of the dilution characteristics of the coastal waters off tuticorin is presented in thebackground of setting up of a desalination plant. simulations of dispersion and spreading of the proposeddischarges has been carried out. scenarios of dilutions were assessed based on the results of a 2d model using the advection-dispersion theory. it is observed that under prevailing currents in th...

Earlier this year, Sydney officially opened its new water desalination plant, the largest so far in Australia and driven by renewable wind power. It is the third to open in the country but will soon be overtaken by further new desalination plants. Australia's response to the growing demand for water and the increasing scarcity and unpredictability of conventional supplies is being echoed around...

Desalination capacity has rapidly increased in the last decade because of the increase in water demand and a significant reduction in desalination cost as a result of significant technological advances, especially in the reverse osmosis process. The cost of desalinated seawater has fallen below US$0.50/m for a large scale seawater reverse osmosis plant at a specific location and conditions whil...

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...

Reverse osmosis (RO) is being increasingly utilized throughout the world for desalination due to the latest improvements in RO membrane performance and its reduced cost compared to thermal desalination. In this paper, Different media and chemicals have been used for Iron removal to prevent membrane fouling of groundwater reverse osmosis plant located in Shupramant-Giza. The objective is to pres...
