1. A method for treating water, the method comprising:

  • (a) introducing water into a pre-treatment stream;

    (b) generating a gas stream containing at least 3% ozone gas;

    (c) introducing the gas stream into the pre-treatment stream at an injection point, resulting in a mixed-phase stream comprising ozone gas and water;

    (d) passing the mixed-phase stream through a monolith having an inlet end and an outlet end and located downstream from the injection point, resulting in a reaction product;

    (e) separating any undissolved gas in the reaction product from a liquid-phase portion of the reaction product; and

    (f) diverting at least a portion of the liquid-phase portion of the reaction product to an effluent stream;

    wherein the monolith comprises a unitary structure having walls that define parallel channels within the monolith that fill a cross-sectional area of the monolith, wherein gas-liquid flow through the monolith is laminar in nature, and wherein the channels extend through the length of the monolith from the inlet end to the outlet end.
