1. What is the BOD Calculation Formula?

The formula calculates the Biochemical Oxygen Demand (BOD) of domestic sewage based on industrial sewage BOD and population equivalent. This helps in estimating the treatment requirements for municipal sewage treatment plants.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \text{BOD of Domestic Sewage} = \frac{\text{BOD of Industrial Sewage}}{\text{Population Equivalent}} \]

Where:

BOD of Industrial Sewage — Biochemical oxygen demand of industrial sewage (kg/m³)
Population Equivalent — Total strength of wastewater for treatment estimation

Explanation: This formula converts industrial BOD load into equivalent domestic sewage BOD based on population equivalent factors.

3. Importance of BOD Calculation

Details: Accurate BOD calculation is crucial for designing appropriate sewage treatment systems, determining treatment capacity requirements, and ensuring environmental compliance.

4. Using the Calculator

Tips: Enter BOD of industrial sewage in kg/m³ and population equivalent value. Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is Population Equivalent?
A: Population Equivalent refers to the total strength of wastewater expressed in terms of the number of persons whose wastewater would produce the same organic loading.

Q2: Why convert industrial BOD to domestic equivalent?
A: This conversion helps in standardizing treatment requirements and designing municipal treatment plants that can handle both domestic and industrial wastewater loads.

Q3: What are typical BOD values for domestic sewage?
A: Typical BOD values for domestic sewage range from 100-400 mg/L, while industrial wastewater can have much higher BOD values depending on the industry type.

Q4: Are there limitations to this calculation?
A: This calculation provides an estimate and may need adjustment based on specific industrial waste characteristics and local regulations.

Q5: How is this used in treatment plant design?
A: The calculated domestic BOD equivalent helps determine the required treatment capacity and design parameters for municipal sewage treatment plants.
