The sorption of Cs+, Co2+ and Eu3+ ions onto polyacylamide cerium titanate (EGIB) sorbent has been investigated at different reaction temperatures(30, 40, 50 and 60EC 1±EC). The sorption kinetics of these ions onto EGIB sorbent follows the pseudo-first-order rate equation. The sorption capacity was

The effects of various operating parameters on the cell voltage and current efficiency of a laboratory-scale chloralkali (CA) membrane cell were studied at low caustic concentrations (5–22 g/L). Five process parameters studied include anolyte pH (2–5), cell temperature (25–90EC), electrolyte velocit

This paper describes the design and performance evaluation of swirl injectors which find application in the spray flash desalination system at low pressures and temperatures. Water was sprayed into the vaporizer through a swirl injector as fine droplets. The vaporizer was maintained at low pressure.

Diatomite modified by microemulsion (DMM) and manganese oxide (MnD) were used for the removal of chromium ion (III) from aqueous solution. The characters and performance of these two types of modified diatomite on chromium ion (III) adsorption were compared to each other. The results indicate that t

The discharge of textile wastewater containing dyes in the environment is worrying for both toxicological and esthetical reasons as dyes impede light penetration, damage the quality of the receiving streams and are toxic to food chain organisms. A fluidized bed reactor (FBR) with activated carbon as

Low pressure membrane filtration processes are increasingly competing against conventional surface water treatment plants. In comparison with conventional processes, UF technology has many advantages, but it is also important that a kind of membrane is suitably selected and operated. In this paper,

Microbiological contamination of polymeric membranes in the process of their exploitation is an essential problem of membrane technology. It results in the increase of manufacturing costs, destruction of membranes, operating life reduction and secondary contamination of water by the metabolism produ

Sewage and industrial effluent treatment plants are installed with primary and secondary biological treatment units to reduce the discharge of pollution load into the environment. These treatment plants normally reduce the organic load in terms of BOD but not the pollution load in terms of inorganic

This paper shows the principles and the present state of the art of concentrating solar power technology and explains the option for seawater desalination, either using electricity or steam generated in such plants. The economic potential of this technology in the MENA region can cope with the prese

This study proposes a new operation methodology for energy saving in the Fujairah seawater reverse osmosis (SWRO) plant, as the optimum feed pressure is determined at the controlled operating temperature. To this end, two functional models were developed by genetic programming (GP) using two-year op
