  • The recent increase in demand for lithium has led to the development of new brine prospects, The brines are hosted in closed salar basin aquifers of two types that are mature halite salars and immature clastic salars. Salar brines also contain other elements of commercial interest, most notably potassium and boron. As a result, there has been a plethora of new exploration projects focused on the brines hosted in the aquifers of the intermontane-closed basins. The estimate of lithium resources and reserves in these salars depends on a detailed knowledge of aquifer geometry, porosity, and brine grade. Because the resource is in a fluid state, it has the propensity to move, mix, rearrange itself relatively rapidly during the course of a project lifetime, and lower recovery factors compared with most metalliferous and industrial mineral deposits due to reliance on pumping of the brine from wells for extraction. This is unlike any other type of metallic mineral resource and hence a different approach specially focusing on hydrogeology and brine hydrology is required for these prospects.

  • The pickling brine generated from the salting process of kimchi production is difficult to treat biologically due to very high content of salt. When pickling brine is treated and discharged, it cannot satisfy the criteria for effluent water quality in clean areas, while resources such as the salt to be recycled and the industrial water are wasted. However, sterilization by ozone, UV and photocatalyst is expensive installation costs and operating costs when considering the small kimchi manufacturers. Therefore there is a need to develop economical process. The study was conducted on the sterilization efficiency of the pickling brine using electrochemical processing. The electrochemical treatment of organic matters has advantages over conventional methods such as active carbon absorption process, chemical oxidation, and biological treatment because the response speed is faster and it does not require expensive, harmful oxidizing agents. This study were performed to examine the possibility of electrochemical treatment for the efficient processing of pickling brine and evaluated the performance of residual chlorine for the microbial sterilization.

  • The cucumber pickles(pieces types), soaked at 10, 15, and 20% brine concentrations, were fermented for 7 days at 25oC. The pH of sample in 10% brine was lowered faster than that of others. To reach pH 3.7, it took 4 days(10%) , 6 days(15%) and 7 days(20%), respectively. The salt permeated into cucumber rapidly, and it took only 1 day to reach maximum content, thereafter salt contents were maintained constant. The titratable acidity and turbidity of cucumber pickle liquids were increased with fermentation time. Sensory evaluation showed that taste and smell of fresh cucumber, color and texture were decreased, while yeast moldy smell and acidic taste were increased as fermentation proceeded. Higher scores were obtained in acidic taste and smell, yeast moldy taste and smell in case of fermented sample in 10% brine for 4 days. It was concluded that the quality of cucumber pickle was influenced by the salt concentrations of brine.

  • Meat jerky is a type of meat snack with a long shelf life, light weight, and unique sensory properties. However, meat jerky requires a long manufacturing time, resulting in high energy consumption. In this study, beef jerky was prepared by injecting different concentrations of brine at different hot-air drying times (0-800 min). When the brine injection levels were increased to 30%, the drying characteristics of beef jerky, such as drying time and effective moisture diffusivity, were significantly improved owing to the relatively high water content and the formation of porous structures. The physicochemical properties (e.g. meat color, porosity, shear force, and volatile basic nitrogen) of the beef jerky injected with 30% brine were improved owing to the shortened drying time. Scanning electron microscopy images showed that the beef jerky structure became porous and irregular during the brine injection process. Our novel processing technique for manufacturing beef jerky leads to improved quality characteristics and shortened drying times.

  • Epoxy resins are produced by the dehydro condensated reaction with ECH (Epichlorohydrin) and BPA(Bisphenol-A) as raw reactants under sodium hydroxide(NaOH) as a catalyst, and from this reaction, salted water named of brine, which contains ECH derivatives in condition of emulsion as likely as glycidol and polymer resins, is produced as an undesired side product. This brine water is alkaline wastewater and causes process fouling problems by plugging and chemically depositing polymer particles on the surface of inner wall of reactors and pipes, and decreases the biodegradable efficiency in the wastewater process. In this study, the optimization of coagulation and sediment reactions, using inorganic and organic polymer coagulants, were performed to remove the causes occurring the process fouling phenomena. And also, based on this study, the methodologies applicable to the commercial processes including economical analysis were presented.

  • The possibility of using waste brine and cabbage waste from kimchi industry as raw materials for the production of yeast cell mass was investigated. Among four strains of osmotolerant yeast, Candida guilliermondii ATCC 6260 showed the best growth in the waste brine containing about 1.0g/L of reducing sugar and 7% to 12% of NaCl. The growth of C. guilliermondii in waste brine was affected slightly between the temperature range of $25^{\circ}C$ to $35^{\circ}C$ and the initial pH of 3 to 6. The NaCl concentration up to 9% was not inhibitory to the growth of C. guilliermondii and the addition of 10mM of ammonium salts or 5mM of potassium phosphate had no effect on the growth. The growth of yeast reduced BOD of the waste brine by 85% within 24hours. When C. guilliermondii was cultured in waste brine added with cabbage juice extracted from waste cabbage, the cell mass was increased significantly.

  • The possibility of using waste brine from kimchi factory as a substrate for the production of the single cell protein was investigated. The growth of Pichia guilliermondii A9 isolated from waste brine was not inhibited by the NaCl up to 10% (w/v). BOD of the waste brine was reduced to one tenth after 24 hours of yeast culture. The addition of ammonium salt, phosphate, and micronutrients to the waste brine did not enhance the growth of P. guilliermondii A9. However, when the brine was enriched with juice from waste cabbage, the final cell mass increased proportionally with the amount of added organic material, suggesting a practical application for the treatment of two different types of waste produced during kimchi manufacturing.

  • Major characteristics of waste brine from the repeated salting and rinsing processes of Chinese cabbage for Kimchi were investigated. Salt concentration of brine was increased with the number of successive salting steps from 12% after 1st salting step to 14% after 5th step. Total waste brine which is the representative of wastewater produced from salting process of cabbage showed 6-8% salt concentration. The pH values in all samples decreased with the number of reuse of brine and showed pH 5.9 and pH 5.2 for the mixture of brine for quarter-cut and small-cut cabbage, respectively, after 5th salting process. Soluble solid contents increased with repetition and resulted in 14-16 $^{\circ}Brix$. Total brine showed increased COD values with the number of reuse of brine and 40-50 ppm of COD values for both quarter-cut and small-cut cabbages.

  • The evaporative desalination system using solar thermal energy would be the efficient and attractive method to get fresh water from brine due to low carbon dioxide generation. In this research the solar desalination system as a heating source of refrigerant R123 in the evaporator was considered. The circulation of refrigerant in the evaporator can reduce the energy consumption of the system, because of using the latent heat of the refrigerant 123 instead of the sensible heat of present hot water. The system was comprised of the single-stage fresh water production unit on the capacity of 1ton/day with shell and tube type evaporator, heaters instead of solar collector to supply the proper heat to refrigerant, and refrigerant and brine circulation systems. Various operating flowrate and temperature ranges were varied in the experiments to get the optimum design data. The results showed that the optimum flow rate of brine feed rate to evaporator was 1.2Liter/min, and the yield of fresh water was increased as higher temperature of feed brine. It was confirmed that the circulation flowrate of heating source of refrigerant was decrease of one fifth of the present warm water system, and very efficient system for solar desalination.
