What characteristic is true about pure oxygen plants?

Pure oxygen plants are equipped with many alarms due to the inherent dangers and complexities associated with handling and using pure oxygen in wastewater treatment processes. Unlike air, which is composed of around 21% oxygen and is generally safe, pure oxygen creates a higher risk of fire and explosion because it greatly enhances combustion processes. Therefore, systems that utilize pure oxygen require a range of monitoring and alarm systems to ensure safety, including alarms for high pressure, leaks, or any abnormal conditions that could lead to hazards.

The operational challenges also contribute to the need for these alarms. The process of infusing pure oxygen into the treatment system demands careful control of various parameters to ensure efficiency and safety. Alarms help operators respond quickly to any issues, reducing the risk of accidents and ensuring compliance with safety regulations.

While pure oxygen plants may be more efficient in terms of achieving higher dissolved oxygen levels for biological treatment, the complexities of using pure oxygen necessitate a robust safety system, which includes multiple alarms for monitoring conditions in the plant.
