Influent Substrate Concentration Formula:
From: | To: |
Definition: Influent Substrate Concentration refers to the concentration of organic matter or nutrients in the raw wastewater entering a treatment plant.
Purpose: It helps wastewater treatment professionals determine the organic load entering the system for proper treatment design and operation.
The calculator uses the formula:
Where:
Explanation: The formula calculates the substrate concentration by multiplying the organic loading by reactor volume and dividing by the flow rate.
Details: Proper calculation ensures efficient wastewater treatment system design, helps predict treatment performance, and prevents system overload.
Tips: Enter organic loading in kg/m³, reactor volume in m³, and flow rate in m³/s. All values must be > 0.
Q1: What is typical organic loading for domestic wastewater?
A: Typically ranges from 0.1 to 0.4 kg BOD/m³·day for domestic wastewater.
Q2: How does reactor volume affect substrate concentration?
A: Larger reactor volumes can handle higher organic loads but require more space and resources.
Q3: What units should I use for flow rate?
A: The calculator uses m³/s, but you can convert from other units (1 m³/day = 0.000011574 m³/s).
Q4: What factors affect substrate concentration?
A: Population served, industrial contributions, and water consumption patterns all affect influent concentration.
Q5: How accurate is this calculation?
A: It provides theoretical values; actual concentrations may vary due to diurnal flow variations and seasonal changes.
