Table 1 Saturation Content of Oxygen in Water at Different Temperatures

Note: Saturated oxygen needs to be exposed to air in water using an aerator pump for 15 minutes, and the water after removing the aerator pump is saturated. If conditions do not permit, it can be assumed that the air is in a saturated oxygen environment.
