Brine concentration

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

Electrodialysis (ED) was applied to concentrate brine solutions of various concentrations — similar to effluents from the desalination of brackish and industrial water — to about 20%. The consequent reduction in effluent volumes would facilitate a reduction in disposal costs. The energy requirement
