7. CMFR, no reaction. 200 kg of chlorine is accidentally dumped into an olympic-sized swimming pool (50mx25mx2m). The pool is continuously flushed with a continuous flow of 1 L/min fresh water. a. 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

c)
