Applications & Use Cases
- ▸ Dosed in municipal and industrial water treatment to oxidize dissolved iron and manganese into filterable precipitates and to control taste, odor, and color compounds.
- ▸ Used as a pre-oxidant and zebra/quagga mussel and biofouling control agent in raw-water intakes, clarifiers, and pipelines.
- ▸ Serves as a strong stoichiometric oxidant in organic synthesis for converting alcohols, aldehydes, and alkenes, and as a titrant in analytical permanganometry.
- ▸ Applied in mining and metallurgical processing for ore flotation conditioning and removal of contaminants from process streams.
- ▸ Employed for gas-stream and air scrubbing of hydrogen sulfide and other odorous reduced-sulfur compounds in HI&I and industrial scrubber media.
