1. What is the Volume of Aeration Tank Formula?

The Volume of Aeration Tank formula calculates the required tank capacity based on sewage flow, BOD influent concentration, and organic loading rate. This is essential for designing efficient wastewater treatment systems.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ V = \frac{Q \times BOD_i}{VL} \]

Where:

\( V \) — Volume of Tank (m³)
\( Q \) — Sewage Flow (m³)
\( BOD_i \) — BOD Influent (kg/m³)
\( VL \) — Organic Loading (kg/m³)

Explanation: The formula determines the necessary tank volume to handle the organic load based on incoming sewage characteristics and loading rates.

3. Importance of Volume Calculation

Details: Accurate tank volume calculation is crucial for proper wastewater treatment system design, ensuring adequate treatment capacity and efficient organic matter removal.

4. Using the Calculator

Tips: Enter sewage flow in m³, BOD influent in kg/m³, and organic loading in kg/m³. All values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is organic loading in wastewater treatment?
A: Organic loading refers to the amount of organic matter introduced into a treatment system, typically measured as biochemical oxygen demand (BOD) or chemical oxygen demand (COD).

Q2: Why is BOD influent important in tank design?
A: BOD influent concentration determines the organic load that the treatment system must handle, directly affecting the required tank volume.

Q3: What are typical values for organic loading?
A: Organic loading rates vary depending on the treatment process but typically range from 0.1 to 2.0 kg BOD/m³-day for conventional activated sludge systems.

Q4: How does sewage flow affect tank volume?
A: Higher sewage flow rates require larger tank volumes to maintain adequate hydraulic retention time for effective treatment.

Q5: Are there limitations to this calculation?
A: This calculation provides an initial estimate. Final design should consider additional factors such as peak flows, safety factors, and specific process requirements.
