TREATMENT OF RAW BRINES FROM DESALINATION PLANTS
A method for treatment of raw brines from desalination plants (6) having a total salt content greater than 60 g/l, wherein, inter alia, a magnesium ion-containing solution having a magnesium ion content greater than 1 g/l at a temperature between 75° C. and 100° C. is passed through a first vertical...

| Zusammenfassung: | A method for treatment of raw brines from desalination plants (6) having a total salt content greater than 60 g/l, wherein, inter alia, a magnesium ion-containing solution having a magnesium ion content greater than 1 g/l at a temperature between 75° C. and 100° C. is passed through a first vertical column (42) containing a bed packing of zeolite A (84) with a flow direction from top to bottom and the raw brine that is to be treated is passed at a temperature of 30° C. to 45° C. through this packed first column (42) in the direction of flow from top to bottom until the calcium ion concentration of the eluate leaving the first column (42) indicates a breakthrough of calcium ions through the bed of zeolite A (44). |
