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...

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...

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...

A microbial desalination cell (MDC) is a new approach for desalinating water based on using the electrical current generated by exoelectrogenic bacteria. Previously developed MDCs have used only one or two desalination chambers with substantial internal resistance, and used low salinity catholytes containing a buffered or acid solution. Here we show that substantially improved MDC performance c...

Feasibility study on nuclear seawater desalination plant in which a 200 MW nuclear heating reactor (NHR-200) couples with MED processes has being finished at Institute of Nuclear Energy Technology (INET) of Tsinghua university in China, the Chinese government has agreed to built the kind of nuclear seawater desalination plant in Shandong peninsula of China. Two different kinds of MED processes,...

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...
