  • Patent number: 11390542
    Abstract: The present invention relates to a method for increasing the magnesium ion concentration of feed water. The method comprises the steps of providing an inlet flow of feed water (QIN), increasing the concentration of carbon dioxide in said inlet flow QIN to obtain a flow of carbon dioxide-containing feed water (QCO2), and passing said flow QCO2 through a solid bed comprising a magnesium ion source to obtain an outlet flow of treated water (QOUT) having an increased concentration of magnesium ions. The invention further relates to a water treatment system for increasing the magnesium ion concentration of feed water and a corresponding flow reactor.
