D.O Saturation Formula (Correction Factor 0.85):
From: | To: |
Definition: This calculator determines the dissolved oxygen saturation level in sewage when the correction factor is 0.85.
Purpose: It helps wastewater treatment professionals assess oxygen levels in sewage systems for proper biological treatment.
The calculator uses the formula:
Where:
Explanation: The formula accounts for oxygen transfer rates, system capacity, temperature effects, and baseline dissolved oxygen.
Details: Proper oxygen levels are critical for aerobic biological treatment processes in wastewater systems.
Tips: Enter oxygen transfer values, temperature in °C, and operation dissolved oxygen. All values must be positive (except DL which can be zero).
Q1: Why is the correction factor 0.85 used?
A: This accounts for the difference between clean water and sewage conditions in oxygen transfer efficiency.
Q2: What's the significance of temperature in the calculation?
A: Oxygen solubility decreases as temperature increases, so the formula includes a temperature correction.
Q3: What are typical values for oxygen transfer capacity?
A: This varies by system but typically ranges from 0.5-2.0 kg/s/W for wastewater treatment systems.
Q4: How do I measure operation dissolved oxygen?
A: Use a dissolved oxygen meter or probe in the wastewater system.
Q5: What's the 9.17 factor in the formula?
A: This is a conversion factor that accounts for standard conditions and units in the calculation.
