Streaming potentials (SPs) across a porous membrane in various organic–aqueous solutions have been studied experimentally. The effects of both the solvent (including its species and weight percentage) and the electrolyte (including its species and concentration) on the SP are presented respectively.

There is an extensive range of applications where the photovoltaic (PV) systems are already viewed as the best and economical option for electricity supply. These systems are usually stand-alone, and exploit the following advantages of PV electricity: (i) there are no fuel costs or fuel supply probl

A photovoltaic application project was designed to pump drinking water from an appropriate well to a residential complex located in a remote area near the Iraqi-Syrian boarder. The system comprises, solar modules array, voltage controller, inverter and a submersible. A ground storage tank of 130 m3

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

A comprehensive numerical model is prepared to simulate the performance of a MIS solar cell with nonuniform substrate doping profile. The effect of interface states properties on the device conversion efficiency are simulated and investigated by computing the J–V characteristics under dark and illum

The objective of this work is to understand the physical and chemical properties of the standard cure copolymer ethylene-vinyl-acetate (EVA), used as encapsulant, during photovoltaic module encapsulation process and also in field exposure of Algerian Sahara as specific desert climate. EVA samples ar

Bilge waters with different oil-emulsion droplet sizes can be treated successfully using ultrafiltration processes with ceramic membranes. The structure of these membranes has been designed to obtain high permeate fluxes and increase the efficiency of the process. Membranes with very high porosity (

The major ion partitioning effect may be due to steric, Donnan and dielectric exclusion which are collectively described by the Donnan steric pore model and dielectric exclusion (DSPM-DE). The effect of various ion size on charged solute rejection was studied using the DSPM-DE model. Sodium chloride

Desalination provides a sustainable source of fresh water for countries with limited water resources. Progress in the desalination technology made highly competitive to water transportation over long distances. Also, desalination is less harmful to the environment than water dams, which results in s

Direct Capillary Nanofiltration (Direct CNF) is a new technique used for surface water and wastewater treatment in one step without pre-treatment. The CNF membrane module combines the favourable cleaning properties of capillary ultrafiltration membranes with the favourable separation properties of n
