The proposed model is based on the hydration theory of dissolved chemical species in water. The molecular dehydration occurs when the solution system is subjected to critical water loss associated with re-displacement of ionic charges from attached water molecules towards the dissolved molecule. Thi

A simple and efficient method for the behavior description of solar stills, developed on the basis of extensive testing, is theoretically and experimentally evaluated. The method relates the main climatic data and operating conditions of the still with distilled water output in daily and night base

In this paper, the experimental design and computer simulation model of a multi-effect humidification/dehumidification (MEH) solar desalination system has been presented. The pilot plant on MEH was designed, fabricated and tested at the Center for Energy Studies, Indian Institute of Technology Delhi

A novel continuous single-stage solar still that makes use of a phase change energy storage mixture (PCESM) for promoting energy usage has been devised and constructed. The still consists of a module made from an external body of galvanized iron, a frame of galvanized iron, a pan at the bottom of th

A solar still in which charcoal functions both as heat absorber medium and as wick has been constructed. The still presents a 15% improvement in productivity over wick-type stills, is cheap, simple to construct, and in addition has the advantages of low thermal capacity, lightweight and ease of oper

Egypt confinement governorates suffer a big shortage in water resources. In a previous study, the problem has been resolved for North Sinai, South Sinai and Matrouh governorates. Meanwhile, the problem still stands for the Red Sea Governorate. In this region, the population is less than 0.2% of Egyp

The paper gives a review of concentrating solar power technologies and shows their perspectives for sustainable development and climate protection. New concepts for the combined generation of power and water are presented together with instruments for enhanced project assessment using remote sensing

This paper presents the development of a new process to desalinate seawater using solar energy. By the proposed process, the solar energy heats airflow up to a temperature between 50 and 80°C. The moderate solar heated air will be humidified by injecting seawater into the air stream. Later on, the w

GECOL and a consulting consortium of experts from ZSW, German Wind Energy Institute (DEWI) and Lahmeyer International (LI) are preparing the installation of an experimental plant for seawater reverse osmosis desalination powered from renewable energy sources (SWRO+RES) at Libya’s coast of the Medite

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
