Photovoltaic based reverse osmosis desalination systems (PV/RO) present an effective method of water desalination especially in remote areas. The increase of the feed water temperature leads to an amelioration of the plant performances. Photovoltaic Thermal Collector (PV/T) represents an ideal power source as it provides both electric and thermal energies for the reverse osmosis process. Nevert...

Microbial desalination cells (MDCs) hold great promise for drinking water production because of potential energy savings during the desalination process. In this study, we developed a continuously operated MDC--upflow microbial desalination cell (UMDC) for the purpose of salt removal. During the 4-month operation, the UMDC constantly removed salts and generated bio-electricity. At a hydraulic r...

We have designed a porous nanofluidic desalination device, a rotating carbon nanotube membrane filter (RCNT-MF), for the reverse osmosis desalination that can turn salt water into fresh water. The concept as well as design strategy of RCNT-MF is modeled, and demonstrated by using molecular dynamics simulation. It has been shown that the RCNT-MF device may significantly improve desalination effi...

s The use of brackish water in the Saloum Delta in Senegal can be made by combining the processes of desalination as a source of solar energy, usually thermal and photovoltaic processes for membrane distillation. But the demand for energy is growing; the use of solar energy can be a good solution, given the high solar potential in these areas. Different experiences around the world have shown t...

The purpose of this study is to propose a theoretical framework based on a balanced scorecard (BSC) for performance measurement in the water desalination supply chain (WDSC). The reason for choosing this context is that the supply chain (SC) of water desalination has received a great amount of attention, due to issues related to the increased need of fresh water for agricultural, industrial and...

The ever increasing demand of water permits the need of alternative water sources for balancing the water supply and demand. Desalination has become a significant alternative water source due to growing demand of water and inadequate conventional water sources in many countries. Desalination is a process of removing excess salts and other dissolved solids from water in order to get clean water ...

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...

The objective of this paper is to introduce models to determine an effective, feasible, and cost-efficient strategy for Saudi Arabia’s water supply system to meet its projected demand in 2025. This paper uses cost minimizing and production maximizing approaches to build the models. The water management system is divided into three processes–desalination, distribution, and wastewater treatment. ...

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...
