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
