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...

Submit Manuscript | http://medcraveonline.com Reverse osmosis (RO) membranes are commonly used for sea water desalination to produce fresh water. These membranes are usually prepared using interfacial polymerization. Hydrophobic diamine and water-soluble chloride salt precursor are reacted to form a thin polyamide (PA) separation layer on a porous support [1]. The PA cross-linking density has a...

A microbial desalination cell (MDC) is able to desalinate salt water without energy consumption whilst generating bioenergy. Previously MDCs used abiotic cathodes, which are restricted in application by high operating costs and low levels of sustainability whereas, in the present study, an aerobic biocathode consisting of carbon felt and bacterial catalysts was tested. The biocathode MDC produc...

Two major reverse osmosis seawater desalination plants are planned for construction in Spencer Gulf and Gulf St. Vincent, South Australia. A state-of-the-art and carefully calibrated hydrodynamic model (COHERENS) is employed to predict the fate of desalination brine in these sheltered inverse estuaries. In this study, we assume that the brine discharged has a salinity being twice that of ambien...

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...
