Ozone mixing system for a hydrotherapy spa

A mixing system for ozonating water of a hydrotherapy spa, said mixing system comprising:

• a reservoir containing a water to be ozonated;
• a reservoir outlet line in fluid communication with said reservoir for withdrawing said water to be ozonated from said reservoir;
• an ozone source having an ozone source outlet line;
• a split in said reservoir outlet line, said split providing a first ozone injector inlet line for a first portion of said water to be ozonated and a second ozone injector line for a second portion of said water to be ozonated;
• a first ozone injector having a first ozone injector outlet line and receiving said first ozone injector inlet line and said ozone source outlet line, wherein said first ozone injector contacts said first portion of said water to be ozonated from said first ozone injector inlet line with a fresh ozone stream from said ozone source outlet line to form a first solution of water and ozone and discharges a first mixture containing said first solution of water and ozone and an undissolved ozone stream via said first ozone injector outlet line;
• a recapturing unit having a recaptured ozone cutlet line and receiving said first ozone injector outlet line, wherein said recapturing unit separates said undissolved ozone stream and said first solution of water and ozone from said first ozone injector inlet line;
• and
• a second ozone injector having a second ozone injector outlet line and receiving said recaptured ozone outlet line and said second ozone injector inlet line, wherein said second ozone injector contacts said second portion of said water to be ozonated from said second ozone injector inlet line with said undissolved ozone stream from said recaptured ozone outlet line to form a second solution of water and ozone.
