1. What is Temperature when Correction Factor is 0.8 Calculator?

Definition: This calculator estimates the temperature in an aeration tank based on oxygen transfer parameters and a correction factor of 0.8.

Purpose: It helps wastewater treatment professionals determine the optimal temperature for biological processes in aeration tanks.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ T_a = \log\left(\frac{N \times 9.17}{N_s \times (D_s - D_l) \times 0.8}\right) \times \frac{1}{\log(1.024)} + 20 \]

Where:

\( T_a \) — Temperature in aeration tank (°C)
\( N \) — Oxygen transferred (kg/s/W)
\( N_s \) — Oxygen transfer capacity (kg/s/W)
\( D_s \) — Dissolved oxygen saturation (kg/m³)
\( D_l \) — Operation dissolved oxygen (kg/m³)

Explanation: The formula calculates the temperature based on the oxygen transfer efficiency with a correction factor of 0.8.

3. Importance of Temperature Calculation

Details: Proper temperature control ensures optimal biological activity in wastewater treatment, affecting treatment efficiency and energy consumption.

4. Using the Calculator

Tips: Enter all required oxygen parameters. Ensure (Ds - Dl) > 0. The calculator uses a fixed correction factor of 0.8.

5. Frequently Asked Questions (FAQ)

Q1: Why is the correction factor set to 0.8?
A: 0.8 is a typical value accounting for oxygen transfer efficiency in standard aeration systems.

Q2: How does temperature affect aeration efficiency?
A: Higher temperatures generally increase biological activity but decrease oxygen solubility in water.

Q3: What's a typical range for dissolved oxygen saturation?
A: At 20°C and sea level, saturation is about 9.1 mg/L (0.0091 kg/m³), varying with temperature and pressure.

Q4: When would I need to adjust the correction factor?
A: For different aeration systems or water conditions, the factor may range from 0.7 to 0.9.

Q5: How accurate is this calculation?
A: It provides a good estimate but actual conditions may vary due to factors like mixing efficiency and water chemistry.
