Brine Brine is used for food processing and cooking (pickling and brining), for de-icing of roads and other structures, and in a number of technological processes. It is also a by-product of many industrial processes, such as desalination, and may pose an environmental risk due to its corrosive and toxic effects, so it requires wastewater treatment for proper disposal. Saline water with relatively high concentration of salt (usually sodium chloride) occurs naturally on Earth's surface (salt lakes), crust, and within brine pools on ocean bottom. Numerous processes exist which can produce brines in nature. Modification of seawater via evaporation results in
Brine and fruit in a process known as pickling. Meat and fish are typically steeped in brine for shorter periods of time, as a form of marination, enhancing its tenderness and flavor, or to enhance shelf period. Elemental chlorine can be produced by electrolysis of brine (NaCl solution). This process also produces sodium hydroxide (NaOH) and Hydrogen gas (H). The reaction equations are as follows: Brine is used as a secondary fluid in large refrigeration installations for the transport of thermal energy from place to place. Most commonly used brines are based on inexpensive calcium chloride and sodium chloride. It is
