The use of inorganic membranes in pollution treatment is actually limited by the cost of such membranes. Advantages of inorganic membranes over organic ones are their chemical, thermal and pH resistance. In this study, low cost ZnAl2O4-TiO2 ultrafiltration membranes were tested for removing Cd(NO3)2

Good characterization of raw water quality and subsequent identification of the most appropriate pre-treatment are not sufficient to ensure successful functioning of a reverse osmosis plant. The Tan Tan demineralization plant was set up in July 2003 for 20 l/s production capacity. The brackish water

The process of electro deposition of heavy metals on bodies of different materials (for instance on non metallic objects to improve their look, their mechanical resistance and other physical properties) generates effluents contaminated by residues of valuable metal salts whose disposal is difficult

This paper is concerning the performance evaluation of small size thermal vapour compression (TVC) desalination units. The plant consists of two identical vapour compression units, each of a nominal capacity of 375 m3/d of distillate water. Despite the fact that these units are fairly new (two years

This work presents a computer program developed for sizing and simulating a solar-powered desalination station using the SMCEC principle. This is motivated by the absence of such software in this area. The computer package includes mathematical models for different compartments of the desalination u

This paper describes part of the emergency rehabilitation works in water sector in Southern Iraq, immediately after the Second Gulf War. The first section is a survey on surface water availability in Iraq, while the second section is focused on water resources in Basrah Governatorate. The third one

Mineral scaling prediction in industrial processes involving high salinity solutions at high temperatures remains notoriously intricate, due particularly to difficulties incurred by modelling the thermodynamic and kinetic behaviour of the mineral deposits in such systems. In addition to these comple

A project is under development at Padre Island and Mustang Island, Corpus Christi, Texas, combining desalination of brackish groundwater with ASR storage of treated drinking water, both utilizing brackish, confined sand aquifers and clay confining layers at depths of less than 250 m. The combination

The AC impedance technique was used in this study for the evaluation and prequalification of concrete materials prepared with chemical corrosion inhibitors and pozolanic admixtures of GGBS slag. In the Arabian Gulf region, marine seawater corrosion has caused severe concrete deterioration over the p

Water desalination has been supported since 1983 by the Spanish Government to obtain a price of drinking water similar to the average price of water used by households in all of Spain. The support was calculated according to many factors such as the cost of water production (i m!3), energy consumpti
