Why is it crucial to deaerate water before adding pure oxygen in oxygen treatment?

Deaerating water before adding pure oxygen in oxygen treatment is crucial because it effectively removes all dissolved gases, particularly oxygen and carbon dioxide that could cause interference in the treatment process. By eliminating these gases, the chemical reactions involved in the treatment can proceed without complication. Any residual gases might react with the introduced oxygen or create undesirable conditions that could hinder the effectiveness of the process.

When the water is deaerated, it ensures that pure oxygen can be introduced and utilized effectively, maximizing the benefits of the treatment. This is particularly important in applications like boiler feedwater or coolant systems, where the presence of dissolved gases can lead to operational inefficiencies or promote corrosion. Hence, achieving the proper chemical environment through effective deaeration is essential for the successful implementation of oxygen treatment.
