Solar desalination

There has been an increasing interest in using exergy as a potential tool for analysis and performance evaluation of desalination processes where the optimal use of energy is considered an important issue. Unlike energy, exergy is consumed or destroyed due to irreversibilies in any real process and

Single basin solar still is a popular solar device used for converting available brackish or waste water into potable water. Because of its lower productivity, it is not popularly used. Numbers of works are under taken to improve the productivity of the still. The still productivity depends on param

Single basin solar still is a very simple solar device used for converting available brackish or waste water into potable water. This device can be fabricated easily with locally available materials. The maintenance is also cheap and no skilled labor is required. This device can be a suitable soluti

Solar-powered desalination is an attractive and viable method for the production of fresh water in remote arid areas. One of the most important factors determining desalination decisions is economics. This paper presents an economic assessment performed to estimate the expected water cost, which is

This paper presents a hybrid solar desalination process of the multi-effect humidification dehumidification and the basin-type unit. The sketch of the hybrid solar desalination process is given. The solar vacuated tube collector is employed in the desalination system, multi-effect humidification deh

This paper presents a performance optimization of solar multi-stage flash (MSF) desalination process using Pinch technology. Three different situations were studied by using pinch analysis in this paper, respectively. Firstly, the distilled water is not discharged in each middle stage. Secondly, the

The experimental and theoretical study of a solar desalination system located in Cairo, Egypt, is presented in this research. A modification unit is provided to enhance the performance of the solar desalination. The modification unit includes a solar parabolic trough (solar energy concentrator) with

A small-scale stand-alone solar-driven membrane desalination unit was designed and manufactured under project funding agreement number ICA3-CT-2002-10025 (SMADES). The desalination plant is intended for autonomous operation in arid and semi-arid remote regions with a lack of electricity and drinkabl

In search of new sources of water supply, seawater desalination is increasingly recognized as a viable option. In arid coastal areas, the lack of fresh water coincides often with an abundance of solar energy. Coupling desalination systems with renewable energy technologies is of great importance. Pr

Recent advances in solar-cell technology and membrane-separation technology do promise the economic viability of distributed seawater and brackish-water solar desalting systems in the near future. Reverse osmosis desalting processes driven by photovoltaic solar electricity can have the potential of
