1. A method for degumming and/or refining oil containing impurities, comprising the steps of:

  • providing a flow-through, hydrodynamic cavitation device having a flow path there through;

    pumping oil containing impurities into the flow path of the flow-through, hydrodynamic cavitation device at a pre-determined pump pressure;

    mixing a degumming agent with the oil containing impurities;

    generating cavitational features in the oil containing impurities within the flow-through, hydrodynamic cavitation device such that the impurities are transferred from an oil phase to a water phase; and

    separating the oil phase from the water phase.
