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...

Current water desalination techniques are energy intensive and some use membranes operated at high pressures. It is shown here that water desalination can be accomplished without electrical energy input or high water pressure by using a source of organic matter as the fuel to desalinate water. A microbial fuel cell was modified by placing two membranes between the anode and cathode, creating a ...

As population and water demand increase, there is a growing need for alternative water supplies from water reuse and desalination systems. These systems are beneficial to water augmentation; however, there are concerns related to their carbon footprint. This study compiles the reported carbon footprint of these systems from existing literature, recognizes general trends of carbon footprint of w...

Fresh water is required to sustain life. However, the world is facing a global challenge to reliably supply its population with safe water due to shortages stemming from population growth, climate change, contamination of available fresh water supplies, and public policy. Presently, the United Nations estimates that one third of the world’s population ( 2.4 billion people) is living in water-st...

Clean Carbon Cycle In article number 2100217, Andrea Fratalocchi and co-workers present a green energy transition that the clean coal desalination technology could open. This help phase out coal-powered plants, reduce thousands of tonnes CO2 every hour, open to new circular economy for global access sanitation freshwater production.

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...

The environmental issues of possible concern during construction and operation of desalination plants (mainly large-scale facilities) include impacts that are common to many coastal development projects (e.g. land use and aesthetic impacts), as well as specific impacts associated with the elements of the desalination system and auxiliary infrastructure. In the latter category these relate to th...

abstract aims: one of the consequences of taking ground water into surface is changing its chemical quality, specially increasing the concentration of dissolved salts. this research was performed in order to analyze growth possibility of heterotrophic bacteria in the membrane of active desalination plants in kashan city, iran. instrument & methods: this descriptive cross-sectional study was don...

This paper investigates the simulation of a hybrid desalination system composed of multi-effect evaporation with thermal vapour compression desalination (METVC) and reverse osmosis (RO) plant. The hybrid desalination system is also integrated with a gas turbine power plant through a heat recovery steam generator (HRSG). First, a comprehensive Thermodynamic model for HRSG, METVC, and RO are deve...

• China will have enough nuclear power by 2030 to eradicate water scarcity. • Nuclear desalination would be affordable even for the poorest Chinese households. • It emits hundreds of times less CO2 than the STNWTP and coal desalination. • Nuclear desalination should be used to supply water to the coastal demand centers. • Water supply from STNWTP should be limited to remote provinces. a b s t r...
