Solar desalination

A parametric investigation was theoretically performed for the vertical multiple-effect diffusion-type solar still, which consists of a number of vertical partitions in contact with saline-soaked wicks with narrow gaps between the partitions, coupled with a heat-pipe solar collector. The proposed st

The object of this research is to experimentally investigate the principal operating parameters of a new desalination process working with an air multiple-effect humidification–dehumidification method. A test set-up was designed and constructed to carry out and optimize this technique. The main part

This paper presents the characteristics of a solar desalination system based on the humidification–dehumidification principle. The system which, can be used in an open or closed cycle for air, is a modular one. It has the following independent components: two solar collectors, an evaporator and a co

The performance of a newly designed solar air plate collector was investigated. A comparison between indoor and outdoor results of the experiments are presented. Graphs of collector efficiency for different operating conditions were established. Solar irradiation intensity, airflow rate and wind vel

This paper presents an experimental and theoretical study of a pad humidifier used in a new multi-stage solar desalination process in operation in Tunisia. The experimental operation of the humidifier is presented in terms of temperature, relative and absolute humidity, and the quantity of evaporate

We proposed a newly designed, compact multiple-effect diffusion-type solar still consisting of a heat-pipe solar collector and a number of vertical parallel partitions in contact with saline-soaked wicks. The solar collector and the vertical multiple-effect diffusion-type solar still can be folded o

Major desalination processes consume a large amount of energy derived from oil and natural gas as heat and electricity. Solar desalination, although researched for over two decades, has only recently emerged as a promising renewable energy-powered technology for producing fresh water. Solar desalina

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

Solar thermal systems that produce potable water from salty water have been studied for quite some years, and the use of solar energy to produce potable water was known in ancient Egypt. Various solar thermal systems have been presented in the literature. The most studied model, the still type solar

In this study, modeling and performance analysis of a single-basin solar still with the entering brine flowing between a double glass glazing is investigated. The base area of the solar still is 1 m². The function of this arrangement is two-fold; lowering the glass temperature and preheating the ent
