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...

In this research, a rotating solar still that uses external bottom reflectors was experimentally investigated. The solar still and reflectors have the capability to shift their angle with respect to the south and the reflectors have the capability to shift their angle with respect to the horizon. The experiment has been performed in both fixed and rotating states. For the fixed state the solar ...

Passive solar vapor generation represents a promising and environmentally benign method of water purification/desalination. However, conventional solar steam generation techniques usually rely on costly and cumbersome optical concentration systems and have relatively low efficiency due to bulk heating of the entire liquid volume. Here, an efficient strategy using extremely low-cost materials, i...

Photovoltaic power generation is a growing renewable primary energy source, expected to assume a major role as we strive toward fossil fuel free energy production. However, the photovoltaic efficiencies limit the conversion of solar radiation into useful power output. Hybrid systems extend the functionality of concentrating photovoltaics (CPV) from simply generating electricity, to providing si...

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 rising demand for clean water and the environmental challenges associated with fossil fuels have encouraged application of renewable greener energy systems in desalination. Moreover, small footprint high productivity favored membrane-based process industry. In past few decades, noticeable work has been performed on development applicability desalination processes powered by sources such as ...

This manuscript investigates the supercritical carbon dioxide (sCO2) power cycle employed in block of concentrated solar (CSP) plants—solar tower—as an alternative for desalination, developed with either distillation or reverse osmosis. concept is investigated as a possible up-scaling SOLMIDEFF project, originally based on hot-air micro gas turbine combined dish collector. For upscaled concept,...

Interfacial solar evaporation has attracted substantial research interest as an eco-friendly means of desalination. A great deal work been devoted to exploring broad-spectrum absorbers, porous floating systems, and appropriate thermal insulations. During desalination, salt accumulation may block the channel severely decline rate. Herein, we designed a salt-resistant evaporator ([email protected...
