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...
یکی از روشهای تولید آب شیرین در مناطقی که با کمبود آب آشامیدنی، کشاورزی و یا صنعتی مناسب مواجه هستند به کارگیری آب شیرینکنهای حرارتی چند مرحله ای [1]برای شیرینسازی آب دریاست که به روش تبخیری-تقطیری عمل میکنند. دمای آب دریای ورودی به همراه سایر عوامل از مهمترین پارامترهای تاثیر گذار بر روی راندمان این سیستمها میباشد. در این مطالعه، برای افزایش راندمان سیستمmed ، طرحی جدید ارائه شده است. ا...
This study proposes a new seawater desalination process using concentrated solar energy. Compared with conventional technologies, the proposed produces tap water high energy efficiency and lower environmental impact. The is based on type of boiler via “beam-down” optical system. To improve productivity, steam produced used to feed an adapted multiple-effect distillation (MED) A complete model f...

In this study, a new proposed multi-generation system as a promising integrated energy conversion system is studied, and its performance is investigated thermodynamically. The system equipped with parabolic trough collectors and biomass combustor to generate electricity, heating and cooling loads, hydrogen and potable water. A double effect absorption chiller to provide cooling demand, a proton...
In this paper, a new thermodynamic cycle for power and fresh water production is presented, which includes MED-TVC desalinations Allam cycles due to the important influence they have on electric industry in controlling limiting greenhouse emissions. First, analyzed appropriate location heat-extraction identified produce required vapor desalination system. It was determined that heat site suitab...
Environmental issues related to desalination are a major factor in the design and implementation of desalination technologies. An acceptable desalination plant is expected to meet environmental regulations; be cost-effective in terms of construction, operation and management, as well as the costs associated with monitoring and permit fees. Some major environmental concerns include issues relate...
A large number of resources are dedicated to seawater desalination and will only grow as world-wide water scarcity increases. In arid areas with high temperature and salinity seawater, thermal desalination and power plants (dual-purpose/co-generation plants) are often employed for the production of power and water. In other areas, reverse osmosis is commonly employed. However, both technologies...
