The easiest way to remove uncontaminated brine from desalination plants and cooling towers is to bring them back to sea. To limit the impact on the environment, it can be diluted with another stream of water, for example. B.dem failure of a sewage treatment plant or power plant. Because brine is heavier than seawater and would accumulate at the bottom of the sea, it requires methods to ensure proper diffusion, such as installing underwater diffusers in sewers.  Other methods include drying in evaporation ponds, injecting into deep wells, and storing and reusing brine for irrigation, defrosting or dust control.  Soil is a common product in food processing and cooking. Brining is used to store or season food. Brining can be applied to vegetables, cheeses and fruits in a process known as beita. Meat and fish are usually brined for shorter periods, such as a form of marination, to improve its tenderness and taste, or to improve shelf life. CIECH S.A. The companies and GAZ-SYSTEM have agreed on other conditions of the joint venture, which includes the construction of a salt mine and a gas tank on the Damaslawek salt dome by GAZ-SYSTEM.
The two companies signed other documents: a terminology sheet and an agreement on the development of design documents. This is a new step in the implementation of the project that the CIECH group, a raw material for the production of soda and salt, must ensure the long-term diversification of salt sources. The brine of underground gas and crude oil deposits is the basic raw material for the production of soda and evaporated salt – the pillars of the CIECH Group`s product offering. In Polish and Romanian soda factories, CIECH buys third-party salts and has its own source of raw material in the case of the German soda factory. The brine is naturally on the surface of the earth (salt lakes), crust and in brine basins at the bottom of the sea. Highly concentrated solesees are usually caused by the evaporation of groundwater at high ambient temperatures. Brine is used for food processing and cooking (pickling and brining), for defrosting roads and other structures, and in a number of technological processes. It is also a by-product of many industrial processes, such as desalted, and may pose a risk to the environment due to its corrosive and toxic effects, which requires wastewater treatment for proper disposal or subsequent use (fresh water recovery).
 Brine is a highly concentrated saline solution (NaCl) in water (H2O). In different contexts, brine can relate to saline solutions of about 3.5% (a typical concentration of seawater, at the bottom of the solutions used to make food bubbling) up to about 26% (a typical saturated solution depending on the temperature).
