Dewatering of High Salinity Brines by Osmotically Assisted Reverse Osmosis
In reverse osmosis (RO), the upper concentration limit to which a brine can be dewatered is about 90 g/L total dissolved solids (TDS). This limitation contravenes the use of RO for the management of brines extracted for subsurface pressure management inthe geologic carbon dioxide storage (GCS). Some extracted GCS brines have a total dissolved solid...
