Odor Control and Hydrogen Sulfide Removal with Hydrogen Peroxide
Hydrogen sulfide, H2S, is a common taste and odor compound found in underground potable water sources, characterized by a rotten-egg odor and metallic taste. OxyPure™ successfully oxidizes H2S to remove the taste and odor associated with sulfides. The oxidation reaction can be controlled under alkaline conditions to produce soluble sulfate and a minimal amount of colloidal sulfur. Hence, turbidity is minimized.
H2S + 4 H2O2 → SO4 2- + 4 H2O + 2 H+
