• A simple model describing countercurrent single-pass electrodialysis is established. • Concentration distribution along the membrane is calculated. • Influence of concentration distribution on scaling risk is discussed. A simple model based on division of electrodialyzer into the elementary units a

In our present work, the preliminary electrodialytic desalination of wastewater containing 75 mg/L of boron and approximately 1.8 g/L TDS was investigated, as the first step in two-stage boron removal ED process. The wastewater in question originated from Tarnowskie Gry landfill chemicals storage.

At “Debiensko” Desalination Plant salt crystallizer is supplied with untreated brine concentrated by RCC evaporation method that results in high energy consumption and huge amount of post-crystallization lye. Nanofiltration pre-treatment of coal-mine brine was then considered to improve plant outcom

In the case of the most troubling saline waters with CaSO4 content close to saturation level, electrodialysis reversal (EDR) was found to be serviceable as a desalination method since its laboratory and commercial applications report stable long-term operation at high CaSO4 concentrate supersaturati

2 2 Nanofiltration of saturated calcium sulfate solution of 0.02 mol/L calcium content, with CO3 !/SO4 ! molar ratio !3 !4 2 ranging from 0.0500 to 2.8×10 was carried out in 6.5×10 m active membrane area laboratory module at 1.2×106 Pa transmembrane pressure using the total retentate recycle mode. P

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

Several hybrid systems, which are developed now, namely NF-MSF, NF-RO-MSF, NF-RO-MD and others offer promising performance. An integrated system for complete usage of components in seawater is also being considered. In all the aforementioned systems NF as water pre-treatment method is applied and a
