curves to determine Brine draw rate
then use the formula
to draw (in L) / draw rate (L/min)
Use the formula : Slow rinse time =
Slow rinse time = (3xBV) (Liters) /
slow rinse rate (L/min)
Typ. allow minimum 2 BV fast rinse :
Use the formula : Fast rinse time =
Fast rinse time = (2xBV) (Liters) /
fast rinse rate (L/min)

Example
Example to draw 1 gallon
(3.78 L) of KMnO4 solu-
tion, with injector J @ 50
psi; Draw time =
3.78/0.98 = 4 min.
Exemple to rinse
25 L of media using
injector J @ 50 psi;
Slow rinse time = (3x25)/
1.1 7 = 64 min.
Example to rinse
1 Cuft of media in
a 10" vess. diam. with
6 gpm DLFC : Fast
rinse time = 2x25 /22.5
= 3 min.
Permanganate feeder
must be used
(with float level control)
