Modeling the Influence of Ionic Strength on Mineral Solubility in Concentrated Brine Solutions
Quantifies CaSO4 and Mg(OH)2 solubility behavior in concentrated Kuwaiti desalination brines and supports precipitation control.
Research problem
Desalination and industrial brines contain high concentrations of salts and sparingly soluble minerals. These streams create scaling, disposal and environmental challenges, but they also contain recoverable resources. The research collected here focuses on how ionic strength, mixing, precipitation kinetics and membrane-module hydrodynamics can be used to control scaling and improve mineral recovery.
