PROCEDURE C:
FREE AVAILABLE, TOTAL AVAILABLE & COMBINED
CHLORINE IN THE PRESENCE OF BROMINE
1. Perform the test for free and combined chlorine as previously described.
2. Perform the test for bromine in the presence of chlorine.
Calculations:
Residual Bromine (ppm) = Reading BR
Free Chlorine in the Presence of Bromine = Free Chlorine - 0.45 (Reading BR)
Total Chlorine in the Presence of Bromine = Total Chlorine - 0.45 (Reading BR)
Combined Chlorine in the Presence of Bromine = Total Chlorine - Free Chlorine
NOTE: Combined chlorine is not affected by the presence of bromine, so the
calculation is the same as when only chlorine is present.
