Brackish Water Desalination

Brackish water desalination focuses on the use of alternative water resources that exhibit higher TDS levels than potable water, but lower TDS levels than seawater (in the range of 1,000 mg/l TDS to 25,000 mg/l TDS). Brackish waters can be found in coastal areas (bays and estuaries, where fresh water mixes with salt water), in aquifers (where it is usually referred to as saline water), and in surface waters (salt marshes, for instance, contain brackish water).Brackish water sources produce a number of challenges for use:
