If the chlorinator setting is 35 lbs/day and the flow is 1.15 MGD, what is the chlorine dosage?

To determine the chlorine dosage in mg/L, you need to use the formula that relates the chlorinator setting (in lbs/day) to the flow rate (in million gallons per day) and convert the units accordingly.

First, you have a chlorinator setting of 35 lbs/day and a flow rate of 1.15 million gallons per day (MGD). The dosage can be calculated using the following formula:

[

\text{Dosage (mg/L)} = \frac{(\text{Chlorinator Setting in lbs/day}) \times 8.34}{\text{Flow Rate (MGD)}}

]

Here, 8.34 is a conversion factor that converts lbs per day to mg/L when dealing with flow in million gallons.

Now, substituting the provided values into the equation gives:

[

\text{Dosage (mg/L)} = \frac{35 , \text{lbs/day} \times 8.34}{1.15 , \text{MGD}}

]

Calculating this step-by-step:

1. First, multiply 35 lbs/day by 8.34:

35 \times 8.34 = 292.9
