TL;DR: A new ion exchange process with batch biological denitrification and reuse of the spent brime reduced the salt consumption and waste discharge by more than 90 percent and proved feasible only when using the nitrate-selective thriethyl- and tributyl-amine resins.
Abstract: Ion exchange with chloride-form anion resin is recommended as a best available technology for removing nitrate from drinking water. Disposal of spent regenerant brine remains a difficult problem, however. A pilot study focused on a new ion exchange process with batch biological denitrification and reuse of the spent brime. Spent regenerant brine from regeneration of the nitrate-loaded ion exchange column was denitrified in a sequencing batch reactor using methanol as a carbon source. After deinitrification, the spent brine was filtered, compensated with NaCl, and reused. Brine denitrification and reuse proved feasible only when using the nitrate-selective thriethyl- and tributyl-amine resins. Compared with the conventional ion exchange process, brine reuse reduced the salt consumption and waste discharge by more than 90 percent.

TL;DR: A method for applying halide brine to surfaces requiring protection against freeze conditions, inhibition of snow and ice accumulating, deicing or freeze retardation, or dust control with limited corrosion is disclosed in this article.
Abstract: A method for applying halide brine to surfaces requiring protection against freeze conditions, inhibition of snow and ice accumulating, deicing or freeze retardation, for example, or dust control with limited corrosion is disclosed, the method comprising the steps of forming an admixture of polyhydroxy carboxylate and polyalkoxylated amine dispersed in a halide brine solution in an amount effective to inhibit corrosion; and applying the admixture to surfaces. The method of this invention can be used to limit corrosion in the application of a halide brine to surfaces of dust-producing materials as well as surfaces requiring protection against freeze conditions.

TL;DR: The authors of as discussed by the authors investigated the salinity of the deep basins filled by hot brines in the Red Sea and found that the transfer of properties across it was controlled mostly by molecular diffusion, and the theoretical loss of heat by diffusion from the brine to seawater was higher than the observed decrease in temperature of the pool during the 20 year period of observation.
Abstract: Many of the deep basins filled by hot brines in the Red Sea have not been investigated since their discovery in the early 1970s Twenty years later, in September 1992, six of these deeps were revisited The temperature and salinity of the Suakin, Port Sudan, Chain B, and Nereus deeps ranged from 2325 to 4460°C and from 144 to 270‰ These values were approximately the same in 1972, indicating that the budget of heat and salt was quite balanced We measured strong gradients of properties in the transition zone between brines and overlying seawater The contribution of salinity to the density gradient was more than one order of magnitude higher than the opposite contribution of temperature across the seawater–brine interface Therefore the interface was extemely stable, and the transfer of properties across it was considered to be controlled mostly by molecular diffusion We calculate that the diffusional transport of salt from the brines to seawater cannot affect significantly the salinity of the brines over a 20 year period, which agrees with the observations The brine pools can persist for centuries with no salt input Therefore, the persisence of brines does not correspond to a steady balance between diffusional loss and continuous input of hydrothermal solutions Deeps that experience only episodical hydrothermal brine supplies may persist for a long time with salt inherited from past inputs The theoretical loss of heat by diffusion from the brine to seawater was higher than the observed decrease in temperature of the brine pool during the 20 year period of observation We calculated that the heat flux out of the pools into the overlying seawater was compensated by a heat flux into the pools of about 250–600 mW/m2 This range of values corresponds to bottom heat flow values that have been reported earlier for the axial zone of the Red Sea In contrast to the other brine pools, the temperature and salinity of the Valdivia Deep brine increased by 41°C and 10‰, respectively, between 1972 and 1992, which is explained by present-day hydrothermal brine discharge

TL;DR: In this article, a process useful for breaking oil in water emulsions produced as the result of a surfactant flood oil recovery project is disclosed, where the produced oil is stabilized with surfactants, content is treated with brine and a polyol or quaternary ammonium compound, or both, followed by mixing and settling to form a sprung oil phase and a brine phase.

TL;DR: In this paper, gelled aqueous compositions in brine solutions having a salt concentration from about 1% to about 10% at a pH of about 3 to about 11 having a water thickening amount of an anionic partially hydrolyzed polyacrylamide and a water-soluble cationic polyamide-epichlorohydrin resin in an amount sufficient to cause gelation and form the gelled composition.
Abstract: Disclosed are gelled aqueous compositions in brine solutions having a salt concentration from about 1% to about 10% at a pH of about 3 to about 11 having (a) a water thickening amount of an anionic partially hydrolyzed polyacrylamide and (b) a water-soluble cationic polyamide-epichlorohydrin resin in an amount sufficient to cause gelation and form the gelled composition. The compositions are useful in the recovery of oil and gas by fracturing and in enhanced oil recovery.
