We have a hot tub that uses ozone (O3) gas as a disinfectant. The ozone generator bubbles ozone in the water and it has a concentration of 2 mg/L of dissolved ozone in the water. I’m concerned that the headspace above the water will have a high concentration of ozone which can be hazardous. For example, OSHA states that the maximum permissible exposure is 0.2 ppmv for a 2 hour exposure. Will the equilibrium ozone concentration in the headspace above the water exceed this limit? The Henry’s Law constant for ozone is: O3(g) ↔ O3(aq) KH = 9.4 x 10-3 mol/L-atm

Question
We have a hot tub that uses ozone (O3) gas as a disinfectant. The ozone generator
bubbles ozone in the water and it has a concentration of 2 mg/L of dissolved ozone in the water. I’m
concerned that the headspace above the water will have a high concentration of ozone which can be
hazardous. For example, OSHA states that the maximum permissible exposure is 0.2 ppmv for a 2
hour exposure. Will the equilibrium ozone concentration in the headspace above the water exceed
this limit? The Henry’s Law constant for ozone is:
O3(g) ↔ O3(aq) KH = 9.4 x 10-3 mol/L-atm
