Sewage Concentration Solution

STEP 0: Pre-Calculation Summary

Formula Used

Sewage Concentration = (Mixing concentration*(Sewage Discharge+Discharge in Stream)-(River concentration*Discharge in Stream))/Sewage Discharge
C_s = (C*(Q_s+Q_s)-(C_R*Q_s))/Q_s
This formula uses 5 Variables

Variables Used

Sewage Concentration - Sewage Concentration can be in terms of bod, do, suspended solids etc.
Mixing concentration - Mixing concentration is the concentration obtained after sewage gets mixed in the river stream.
Sewage Discharge - (Measured in Cubic Meter per Second) - Sewage discharge is the flow rate of sewage when it is being discharged in the river.
Discharge in Stream - (Measured in Cubic Meter per Second) - Discharge in Stream is the volumetric flow rate of water that is transported through a given cross-sectional area.
River concentration - River concentration is the concentration of river parameters like bod, do etc.

STEP 1: Convert Input(s) to Base Unit

Mixing concentration: 1.2 --> No Conversion Required
Sewage Discharge: 10 Cubic Meter per Second --> 10 Cubic Meter per Second No Conversion Required
Discharge in Stream: 60 Cubic Meter per Second --> 60 Cubic Meter per Second No Conversion Required
River concentration: 1.3 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

C_s = (C*(Q_s+Q_s)-(C_R*Q_s))/Q_s --> (1.2*(10+60)-(1.3*60))/10

Evaluating ... ...

C_s = 0.6

STEP 3: Convert Result to Output's Unit

0.6 --> No Conversion Required

FINAL ANSWER

0.6 <-- Sewage Concentration

River Stream Flow Rate

Go Discharge in Stream = ((Sewage Concentration*Sewage Discharge)-(Mixing concentration*Sewage Discharge))/(Mixing concentration-River concentration)

River Stream Concentration

Go River concentration = (Mixing concentration*(Sewage Discharge+Discharge in Stream)-(Sewage Concentration*Sewage Discharge))/Discharge in Stream

Sewage Concentration

Go Sewage Concentration = (Mixing concentration*(Sewage Discharge+Discharge in Stream)-(River concentration*Discharge in Stream))/Sewage Discharge

Mixing Concentration

Go Mixing concentration = (Sewage Concentration*Sewage Discharge+River concentration*Discharge in Stream)/(Sewage Discharge+Discharge in Stream)

Sewage Flow Rate

Go Sewage Discharge = ((River concentration-Mixing concentration)*Discharge in Stream)/(Mixing concentration-Sewage Concentration)

Actual DO

Go Actual Dissolved Oxygen = Saturated Dissolved Oxygen-Oxygen Deficit

Saturation DO

Go Saturated DO = Oxygen Deficit+Actual DO

Sewage Concentration Formula

Sewage Concentration = (Mixing concentration*(Sewage Discharge+Discharge in Stream)-(River concentration*Discharge in Stream))/Sewage Discharge
C_s = (C*(Q_s+Q_s)-(C_R*Q_s))/Q_s

What is BOD?

BOD is a measure of the amount of oxygen required to remove waste organic matter from water in the process of decomposition by aerobic bacteria.

How to Calculate Sewage Concentration?

Sewage Concentration calculator uses Sewage Concentration = (Mixing concentration*(Sewage Discharge+Discharge in Stream)-(River concentration*Discharge in Stream))/Sewage Discharge to calculate the Sewage Concentration, The Sewage Concentration is the concentration of sewage parameters like BOD, DO, suspended solids etc. Sewage Concentration is denoted by C_s symbol.
