as ethylene glycol.

Sodium chloride brine spray is used on some fishing vessels to freeze fish. The brine temperature is generally -5 F. Air blast freezing temperatures are -31 F or lower. Given the higher temperature of brine, the system efficiency over air blast freezing can be higher. High-value fish usually are frozen at much lower temperatures, below the practical temperature limit for brine.

Water softening and purification

Brine is used for regeneration of ion-exchange resins.
