A preventive system that prevents sulfide generation in the sewage force main by injecting oxygen to inhibit the activity of sulfate-reducing bacteria. The oxygen is supplied by an automated, low-cost PSA oxygen generator.
• High oxygen dissolution rate: five times that of air injection
• Eliminates dead-air spaces within sewage force main to inhibit bacterial activity
• Oxygen supply pressure matches the force main's pressure
