Desalination

Fouling of UF membranes by humic acid particles was studied. Six types of UF membranes namely PAN 20 kDa (Rhone-Poulenc), PAN 100 kDa (Osmonics), PES 150 kDa (Microdyn-Nadir) and PS 10, 50 and 100 kDa (Permionics) were tested. Analysis of the results showed that the resistance due to the adsorption

Throughout the world, water scarcity is being recognised as a present or future threat to human activity and as a consequence, a definite trend to develop alternative water resources such as desalination can be observed. The most commonly used desalination technologies are reverse osmosis (RO) and t

The AQUASOL-Enhanced Zero Discharge Seawater Desalination using Hybrid Solar Technology (EVK1CT2001-00102) project is one more attempt at using solar energy for water desalination, improving the economics and the environmental performance of a MED desalination plant. Within the project, an advanced

Throughout the world consumers demand is expanding for a higher level of water quality and quantity. The source of water greatly varies from country to country and in some areas desalination of seawater is the dominant process for potable water. Desalination is a process that removes dissolved miner

In Solar Energy Laboratory, Mechanical Engineering Department, Faculty of Engineering & Technology— Sebha University, an investigation has been conducted of the productivity of solar desalination system working on the basis of evacuation. Solar energy intensity has been concentrated by means of conc

In this work, an approach to study the long-term performance of an industrial water desalination plant is described. Operational data corresponding to the time period of 454 days were analysed and from the results obtained it was found that the normalized water permeability coefficient declined by a

A thermoeconomic analysis of a cogenerative system with steam bleedings produced starting from the thermal energy recovered in a municipal solid waste thermovalorization plant is presented. The authors assume that the bled steam is used to feed a seawater multi-stage flash (MSF) desalination plant.

Ni2+ transport in zirconium hydrophosphate containing 85% water was investigated with the electromigration method. An effective diffusion coefficient of Ni2+ was found to reach 1.14×10!11 m2 s!1. It was shown that zirconium hydrophosphate can be used for discontinuous Ni2+ removal from diluted solut

It was found that the effective diffusion coefficient of Ni2+ in a macroporous strongly acidic cation-exchange resin, which was determined with the electromigration method, depends on acidity and flow rate of the solution. The values of diffusion coefficient were found to be 1.18×10!13-1.9×10!12 m2

The model discussed in a previous work for the simulation of a deaerator to remove the oxygen from seawater in desalination plants has been improved. The conservative character of that model has been revised on the basis of the experimental industrial experience of FISIA Italimpianti S.p.A. In parti
