This method describes the titrimetric determination of the oxygen content of boiler feed water according to the difference method. If the oxygen content of boiler water exceeds a certain threshold, it can cause corrosion to set in. Maintaining the boiler water at a higher pH can reduce the risk of corrosion.
boiler feed water for use in beer and food production
If the oxygen content of boiler water exceeds a certain threshold, it can cause corrosion to set in. Maintaining the boiler water at a relatively high pH can reduce the risk of corrosion.
Refer to W-000.40.115 Oxygen in Water, Titration Method According to WINKLER
Given the minute oxygen concentration in the boiler water, the difference method is recommended. In this analysis, the blank value of the reagent is taken into consideration through titration of the sample free of Mn2+ ("red").
