  • Patent number: 11735399
    Abstract: Exemplary systems and methods associated with activating fluids using indirect plasma. In particular, liquid can be activated to high concentrations and at high volumes by thinning and mixing the liquid as it is exposed to the plasma, resulting more efficient activation. Further increases in activation can be reached by re-circulating fluid for additional exposure to the plasma. High flow rates can be achieved with integrated systems that utilize multiple activation systems with coordinated control.
