Modular ozone-based disinfection system with selectively controlled ozone-to-hydroxyl-radical treatment ratio

A modular ozone-based disinfection system configured to selectively control an ozone-to-hydroxyl-radical treatment ratio, the modular ozone-based disinfection system comprising:

• a purification configuration comprising an air inlet, an air outlet, an air circulation subsystem, and an airflow path extending between the air inlet and the air outlet;
• an electrolytic ozone generator configured to generate ozone from water and introduce the ozone into the airflow path to form ozone-containing air;
• a hydroxyl radical catalyst module positioned along the airflow path and comprising a heating region configured to heat the ozone-containing air;
• a hydroxyl augmentation and ozone reduction module positioned downstream of the hydroxyl radical catalyst module along the airflow path;
• and
• a controller configured to execute a selected oxidant-output profile from among a plurality of oxidant-output profiles;
• wherein each oxidant-output profile of the plurality of oxidant-output profiles is associated with a respective heater output level for the heating region;
• wherein the selected oxidant-output profile causes the controller to select the respective heater output level associated with the corresponding ozone-to-hydroxyl-radical treatment ratio;
• and
• wherein the respective heater output level controls conversion of the ozone into hydroxyl radicals to produce a corresponding ozone-to-hydroxyl-radical treatment ratio in a treated airflow discharged through the air outlet.
