An optimization of the electrodialysis process and an estimation of its costs by the analysis of experimental results of model natrium chloride solutions was compared to the optimization and cost estimation made by using the convective-diffusion hydrodynamic model. A NaCl 0.02 M solution was desalin

Electrodialysis (ED) is applied in Japan for seawater concentrating to ca. TDS 200 followed by thermal concentration and salt crystallization. A partially desalinated water (ED diluate) is obtained at the same time. Its further desalination for potable water production may be considered to decrease

The share of electrodialysis in seawater desalination is very small in contrast to reverse osmosis. It is stated that ED may compete with RO in the range of feed water salinity up to 8–10 g/L only because ED desalination cost is proportional to the amount of salt, which must be carried through the m

In the present work, the supported liquid membrane (SLM) technique has been applied to the desalination of saline water. A simple apparatus designed and constructed in our lab was used to conduct the experiments. Various factors that would affect the degree of desalination were studied and these wer

Membrane technology is widely accepted as a means of producing various qualities of water from surface water, well water, brackish water and seawater. Membrane technology is also used in industrial processes and in industrial wastewater treatment, and lately membrane technology has moved into the ar

This paper deals with systems and equipment to put onboard ships meant for water desalting. The ship is rigged to work offshore, either slowly sailing or, usually, being afloat motionless. The ship is a slightly modified liquid gas carrier. Of course, it also holds both modular and dismountable seaw

Tackling water shortage issues with desalting of seawater and salty water is common in the desert nations of the Middle East and the Mediterranean. The fast growing development in Egypt has required big movements of investments and people from the Nile Valley towards the east, with the fantastic Red

The separation performance of K+ ions from KCl solution has been investigated by electrodialysis at constant voltage mode of operation as a function of flow rate and voltage scanned. TS-1-10 model electrodialysis equipment (Tokuyama) modified with rotameters was employed in experimental runs. The ef

Middle East and North African countries suffer from a large shortage of fresh water. Statistical analysis showed that the fresh water per capita in these countries is less than 13% of the average world per capita. In Libya, the available annual average fresh water is less than 150 l/d/capita, which

The Italian Ministry of Public Works has funded a study aimed at assessing the technical feasibility and financial viability of a disalination plant to be implemented in Agrigento, Sicily. The plant, with a design production capacity of 40,000 m3 and an estimated cost of € 120 million, will serve 19
