Przedstawiono rozwiązanie, w którym woda zasolona poddawana jest wstępnemu uzdatnianiu metodą nanofiltracji (NF) a następnie zatężaniu metodą wyparną lub w zintegrowanym układzie elektrodializa – odwrócona osmoza i dalszemu odparowaniu z krystalizacją chlorku sodu. Na przykładzie solanki z KWK Budryk wykazano, że uzysk soli, dzięki samemu zastosowaniu nanofiltracji, można zwiększyć z obecnej wartości...
Electrodialytic desalination/concentration of brackish water (TDS ca. 10 g/L) in an integrated ED — thermal desalination system was examined. The ED unit stacks geometry, and the ED system arrangement and operating conditions were optimized to identify minimum desalination/concentration costs. The ED stack with relatively low 0.19 mm membrane to membrane distance, and three stage ED system arrangement...
