Students have asked these similar questions
A) # of Disinfection Clearwells: 3
B) Clearwell Operation Style: Parallel (to provide contact time for disinfection
using free chlorine (derived from a hypochlorite solution generated onsite).
C) The facility's existing system to generate hypochlorite onsite has reached
the end of its useful life, and the current operating capacity is insufficient
to generate the required mass flow of hypochlorite to accommodate the
future capacity of 34.5 MGD. Assume the facility plans to stop generating
hypochlorite onsite and will instead purchase a bulk solution of sodium
hypochlorite
D) Sodium hypochlorite (NaOCI) concentration: 6.25% NaOCI by mass
E) Bulk Density: 1,100 kg/m^3
F) Clearwell T10/DT Ratio: (CW1 0.43). (CW2 = 0.51), (CW3 = 0.58)
DT is the theoretical mean hydraulic retention time (V/Q)
G) pH: 7.0
H) Design Temperature: 15°C
1) 50% of Chlorine is lost in each clearwell
J) If the concentration going into the clearwell is C, then you can assume that
the concentration leaving the…
