  • Pretreatment of produced water to facilitate improved metal extraction
    Patent number: 11685676
    Abstract: A water treatment system that removes calcium and magnesium using coagulants and pH controls, aqueous phase organic materials from water using a biological removal system that includes microorganisms and a physical separation system that includes sparging equipment for sparging the water to remove non-aqueous phase liquid organic materials, volatile phase organic materials. An apparatus, system and method for pretreating oilfield produced water to completely remove or significantly reduce concentrations of substances that are known to interfere with downstream recovery of metals including lithium. This technology facilitates a more efficient and cost-effective extraction method from alternate sources to meet the increasing global demand.
    Type: Grant
