What is the difference between brackish water and seawater desalination?
Brackish water refers to water supplies that are more saline than freshwater, but much less salty than seawater. Brackish water may result from mixing of seawater with fresh water, as in estuaries, or it may occur in brackish aquifers. The level of salinity in water is measured in total dissolved solids (TDS). In a reverse-osmosis system, the greater the TDS concentration of the water, the higher the pressure needed for the pumps to push water through the membranes, and consequently, the higher the energy costs.
