A water plant treats 750,000 gallons per day. The normal chlorine dosage is 8 mg/L. If the disinfectant used is 65% calcium hypochlorite, how many pounds of calcium hypochlorite are fed each day?

To calculate the pounds of calcium hypochlorite needed for disinfection, first, determine the total amount of chlorine required in milligrams per day. The treatment plant processes 750,000 gallons per day, and the normal chlorine dosage is 8 mg/L.

1. Convert the gallons of water treated to liters. There are about 3.78541 liters in a gallon, so:

[

750,000 \text{ gallons} \times 3.78541 \text{ L/gallon} \approx 2,839,100 \text{ L}

]

2. Calculate the total daily chlorine requirement in milligrams:

[

2,839,100 \text{ L} \times 8 \text{ mg/L} = 22,712,800 \text{ mg of chlorine}

]

3. Convert milligrams to pounds, knowing that there are 453,592 mg in a pound:

[

\frac{22,712,800 \text{ mg}}{453,592 \text{ mg/pound}} \approx 50.0 \text{ pounds of chlorine}

]

Since only 65% of calcium hyp
