Salinity gradient power (SGP) is based on the chemical potential difference between concentrated and dilute salt solutions. Reverse electrodialysis (RED) can thus be used to produce electricity by a SGP–RED unit. In principle, a highly concentrated solution can be recovered from a seawater desalinat

Performances of solar photocatalytic pilot plant using TiO2-P25 (Degussa) were investigated for removal of commercial azo dye chosen as model compound. Experiments were carried out to optimize various parameters, influencing the performance of the operated thin-film fixed-bed reactor (TFFBR) with an

The aim of this paper is to study the thermal behaviour of a solar air heater as a source of energy for drying agricultural products. The output temperature and velocity of the drying air were first evaluated, and a mathematical formulation of the physical process of solar drying based on convention

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

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

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

This work presents the energy and mass balance equations, the numerical simulation results for the production rate, and the experimental laboratory water tests for a thermal desalination unit with a heat recovery system. The system components are a solar collector and a desalination tower, although
