What is the HRT? b. What is the initial chlorine concentration? c. What is the concentration after 1 HRT? d. What is the concentration after 1 week? Ignore any chlorine reactions and e. How long will it take to reach the standard chlorine concentration of 2 mg/L? f. How many HRT's is this?Explanation / Answer
a) HRT = volume/discharge
= 50*25*2*1000/1 = 2500000 minutes = 41666.67hrs
= 1736.11days
b) Initial chlorine concentration = 200*106/2500000
= 80 mg/l or 80ppm
