Mercaptan Odor Control

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. 

What are 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.

How can odor from Mercaptans and Amines be controlled?

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.  

  • CAIROX® potassium permanganate is a solid granular oxidant used to treat drinking water, wastewater, industrial process chemicals, plus numerous other applications. 
     
  • CAIROX® CR potassium permanganate tablets are used for eliminating hydrogen sulfide odors at remote sites, lift stations, and interceptors where feed equipment is not practical.
     
  • AQUOX® potassium permanganate is offered only in Europe, Middle East, and Africa. Like CAIROX, this brand of potassium permanganate is a versatile oxidant used to treat drinking water, wastewater, industrial process chemicals, plus numerous other applications.
     
  • CARUSOL® liquid permanganate is an effective oxidant recommended for potable drinking water applications that require a concentrated permanganate solution.  Applications include iron and manganese reduction, taste and odor control, disinfection by-product reduction, color reduction, and radium reduction.
