Pilot-scale production of high-purity vaterite-type calcium carbonate from desalination brine using industrial by-products

Key Points

• High-purity calcium carbonate production is feasible from desalination brine, promoting resource recycling.
• The process yielded calcium carbonate with purity levels exceeding 90%, enhancing brine management strategies.
• Analyses involved assessing calcium carbonate from brine using industrial by-products over a pilot-scale duration.
• The findings suggest potential environmental benefits, requiring further investigation into industrial scalability.
