High concentrations of ozone in the gas mixture creates efficiencies system wide: less energy is used because you can use smaller oxygen generators, smaller pumps and dissolution systems and smaller ozone destruct units. This also, of course, affects the investment cost. Dissolution is improved because less gas needs to be dissolved thanks to the high concentration of ozone in the gas – doubling the concentration doubles the dissolution ability of the ozone in the liquid.

Yes, but higher concentrations means smaller gas volumes, reducing the size and cost of the off-gas systems and the energy required.
