• We developed a portable solar-driven desalination system for producing potable water. • A stand-alone system which utilizes solar energy by combining PV/thermal collectors. • The system uses Vacuum-Multi Effect Membrane Distillation (V-MEMD) process. • We also reported some small-scale test result

Integration of renewable energy with desalination technologies is a strongly emerging field in many regions of the world having drinking water and energy crisis. This study presents the results of a techno-economical investigation of a small scale, photovoltaic (PV) powered hybrid nanofiltration (NF)

Baja California Sur (BCS) is an arid sparsely populated coastal state in northwest Mexico. Population growth, agriculture and booming tourism have lead to severe overexploitation of underground aquifers and saline intrusion. This paper reviews the current water and energy situation in BCS. The state

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

In spite of poor efficiency of the photovoltaic systems developed up to date and the high cost of the installations of the equipment of this kind of station of solar energy conversion into electric power, this did not stop the researchers to continue to make efforts in this field in order to minimiz

Solar energy can be converted to electrical energy by means of two methods: the first one is a direct method with photovoltaic (PV) systems and the second is an indirect one by solar thermal power generation. The main disadvantage of the PV systems is the high sensitivity of the output electrical ch

We report on preliminary experience of a laboratory-size reverse osmosis desalination plant employing a photovoltaic energy source. The plant is intended for educational and research purposes. The issues investigated are briefly discussed and preliminary operation measurement data are given. Further

A small-scale seawater reverse-osmosis system with excellent energy efficiency is presented. The system promises to deliver up to 460 l/h of potable water, from seawater (at 40,000 ppm), while consuming less than 1600 W of electrical power. This represents a specific energy consumption of less than

An efficient cost-effective batteryless photovoltaic-powered seawater reverse-osmosis desalination system is described. The system has a modest 2.4 kWp photovoltaic array and yet promises to deliver 3 m3/d throughout the year in an example location in Eritrea, operating from borehole seawater (at 40

Water in many areas of Australia is scarce and of poor quality. In some areas high levels of treatment are required either due to contamination of waters or due to high salinity. Nanofiltration (NF) and low-pressure reverse osmosis membranes are well-recognized technologies to treat waters of qualit
