With the increasing installed capacity of desalination, the greenhouse gas emission for generating the required energy to power the desalination plants is also becoming the focus of attention in the world community. Domestic reverse osmosis membranes have been very successful technology especially in the developing world to provide safe drinking water. The novel concept of photovoltaic powered ...

Growing uncertainty in the future availability of freshwater sources has led to an increase installations for desalination seawater. Reverse osmosis (RO), currently most widely adopted technique, caused environmental concerns over high associated greenhouse gas emissions and generation large amounts chemicals-containing brine. Significant consumption electricity RO is additional challenge, part...

The development of Wyoming’s energy resources (coal bed methane extraction [CBM], hydraulic fracturing) and carbon dioxide (CO2) sequestration sites all invariably result in the production of brackish wastewaters. The treatability of these waters varies from relatively simple for CBM water (dissolved solids < 2,000 mg/L) to complex for the water that is displaced during geologic sequestration o...

Graphene oxide (GO)-enhanced membranes are being developed to solve major limitations in both reverse osmosis (RO) and membrane distillation (MD) technologies, which include high electricity thermal energy consumption. This study performed, for the first time, a life cycle assessment determine effects of using GO-enhanced on environmental impacts seawater desalination via RO MD. Four scenarios ...

In this study, optimization of Qeshm power and water desalting cogeneration plant has been investigated. The objective functions are related to maximizing exergetic efficiency and minimization of exergoeconomic and exergoenvironmental parameters. Also, the integration of RO desalination with the existing plant has been evaluated based on these analyses. This plant includes two MAPNA 25 MW gas t...

New membrane distillation configurations and a new membrane module were investigated to improve water desalination. The performances of three hydrophobic microporous membranes were evaluated under vacuum enhanced direct contact membrane distillation (DCMD) with a turbulent flow regime and with a feed water temperature of only 40 ◦C. The new configurations provide reduced temperature polarizatio...

This paper identifies the best energy management strategy of hybrid photovoltaic–diesel battery-based water desalination systems in isolated regions using technical, economic and techno–economic criteria. The employed procedures include Criteria Importance Through Intercriteria Correlation (CRITIC) Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) as tools solution. Twelve...

With global demand rising faster than availability, fresh water is quickly becoming a limited resource. In fact, the United Nations estimates one third of the world s population is living in water-stressed regions, and by 2025 this number is expected to double. Seawater desalination is an attractive solution to this problem because seawater accounts for more than 97% of the world s water supply...

Reliable production of freshwater and energy is vital for tackling two the most critical issues world facing today: climate change sustainable development. In this light, a comprehensive review performed on foremost renewable energy-driven polygeneration systems using thermal membrane desalination. Thus, designed to outline latest developments integrated desalination based multi-stage flash (MS...

When designing and building an optimal reverse osmosis (RO) desalination plant, it is important that engineers select effective membrane parameters for application performance. The selection can determine the success or failure of entire operation. objective this work to review available types design be selected yield highest potential plant operations. Factors such as osmotic pressure, water f...
