Brine, which remains on the surface as a source of salt water, is called “leaks” or “salt pans.”  The levels of dissolved solids in groundwater vary greatly from place to place on earth, both with regard to specific components (e.g. B halite, anhydrite, carbonates, plaster, fluorinated salts, organic halides and sulphate salts) than in relation to concentration. Using one of the many groundwater classifications based on total dissolved solids (TDS), brine is water containing more than 100,000 mg/L of TDS.  Brine is usually produced during the completion of boreholes, especially after the hydraulic rupture of a borehole. In accordance with the terms of the roadmap, both parties intend to enter into an agreement for the supply of brackière to the CIECH facilities for a period of 20 years, with the right to extend this period for a further 15 years. The price of salt, set out in the agreement, must take into account CIECH`s financial contribution to the construction of the transport infrastructure. The conclusion of the salt supply contract will be one of the conditions for the taxation of investment funds. Other conditions are the obtaining of the necessary authorizations and authorizations, as well as provisions to guarantee the right of both parties to reimburse the expenses incurred. Brine is an auxiliary in water softening and water treatment systems using ion exchange technology. The most common example is household dishwashers that use sodium chloride in the form of dishwasher salt. Brine is not involved in the purification process itself, but is used for the cyclic regeneration of ion exchanger resin. The water to be treated passes through the resin tank until the resin is considered exhausted and the water is purified to a desired level.
The resin is then regenerated by rinsing the resin bed sequentially to remove accumulated solids, rinse the ions removed from the resin with a concentrated solution of substitute ions and rinse the resin rinse solution.  After treatment, the resins exchanging ions saturated with calcium and magnesium ions from the treated water are regenerated by quenching in brine with 6 to 12% NaCl. Sodium ions in brine replace calcium and magnesium ions on pearls.   The easiest way to remove unpolluted brines from desalination plants and cooling towers is to send them back into the ocean. To limit pollution, it can be diluted with another stream of water, for example. B.dem emissions from wastewater treatment or power plants. Since brine is heavier than seawater and would accumulate at the bottom of the sea, methods are needed to ensure adequate diffusion, for example. B the installation of underwater diffusers in sewers.  Other methods include drying in evaporation ponds, injection into deep wells, storage and reuse of brine for irrigation, deglaciation or dust control.  The Term Sheet is a document that lists the conditions for further cooperation, in particular a timetable and general financing principles for each phase of the investment, as well as key assumptions regarding commercial cooperation after the implementation and commissioning of the salt mine and gas storage facility. The second document is an agreement for the drafting of the design documentation for each investment element.
For CIECH, participation in this project implies a diversification of the salt sources that will be delivered to the group`s plants. Under current assumptions, CIECH will co-finance the construction of the mine-based transport infrastructure and underground gas reservoirs to enable the transport of salt to its production facilities. According to preliminary assumptions, the estimated value of the investment in such infrastructure may amount to approximately PLN 450 million and the co-financing share of both parties is determined by negotiation and set out in the investment agreement. . . .
