- 요약Brackish groundwater is widely available in the U.S. yet underdeveloped as a water source due to the complexity of inland brine disposal. In a lifecycle assessment of inland concentrate treatment, we found that the greatest potential for cost and energy savings lies in avoiding energy-intensive crystallization processes (such as mechanical vapor compression) and landfilling of salt solids. Additionally, inland desalination brines contain elevated concentrations of scale species (i.e., dissolved calcium and silica minerals), and improved methods for brine volume minimization and salt valorization must consider the complex chemistries often encountered in inland contexts.Solar-driven interfacial evaporation is a means of enhancing water vaporization efficiency by reducing energy lost to the bulk liquid and localizing solar-thermal energy conversion to the air/liquid interface. The graphene oxide (GO) stalk interfacial evaporator can significantly increase evaporative fluxes for sodium chloride solutions but has not previously been evaluated for use with brines containing scale species. In long-term experiments (8 to 32 days), we assessed the GO stalk's performance for brines containing calcium and silica scalants. We demonstrated its resistance to evaporative flux decline due to salt accumulation over both time scales as well as the ability to increase evaporation rate by antiscalant addition or stirring. Additionally, the GO stalk achieved salt separation during the evaporation of multi-electrolyte brines, in which the calcium to sodium ratio more than doubled for salts collected from the stalk base compared to those collected from the top of the stalk.In some contexts (e.g., intermediate chemical demineralization or concentrate disposal via environmental discharge), it is necessary to remove antiscalant compounds found in inland desalination concentrates. Using a magnetically-removeable ZnFeZr-oxyhydroxide adsorbent, we achieved 60%, 80%, and 95% removals of commonly used phosphonate antiscalants (NTMP, EDTMP, and HEDP, respectively) from synthetic brine solutions. The processes also removed metal contaminants (PbII and CuII) at rates of 60% and 90%.
