ABSTRACT:
Non-brackish water can be produced from the brackish water or brine containing at least 500 ppm total dissolved solids coproduced in many active hydrocarbon product wells and found in many inactive gas wells. The brackish water or brine is desalinated producing non-brackish water, preferably, potable water. A preferred method of desalination is by reverse osmosis.
