The anaerobic decomposition of organic matter in wastewater results in the formation of hydrogen sulfide. However, these conditions also lead to the production of other odor compounds, such as mercaptans and amines.
Mercaptans are organic sulfur compounds while amines are organic nitrogen compounds that incorporate a characteristic ammonia structure. Both have very low and unpleasant odor recognition concentrations.
As a strong oxidizer, permanganate goes beyond the destruction of hydrogen sulfide alone. It attacks the characteristic odor structure of these molecules, eliminating their odors as well.
