What are the major elements contained in the waste brines (the initial substrate)? Are they constant in terms of composition over the production cycle or does the composition of the brine wastes varies significantly over time?

Fulvio, Thank you for the question. The reject brine was obtained from a desalination plant in the UAE and the process was based on multi-effect distillation. The major elements of the brine are sodium, chloride, calcium, sulfate and magnesium ions. CaO was used as the reagent in the precipitation process. The concentration was a multiple of the saturation concentration at 25 C. The required amount of CaO was added into the brine and the mixture was stirred until equilibrium. In that case,the composition of the solution was not constant due to precipitation of solids.
