BIOXIDE® Calcium Nitrate Solution

A safe, natural solution for the elimination of odor and corrosion

BIOXIDE® Calcium Nitrate Solution eliminates the odor, corrosion, and safety problems associated with hydrogen sulfide by achieving sewage odor control naturally, rather than chemically. This unique, proven product also treats other common sewage odors, including odorous sulfur compounds such as mercaptans and organic sulfides.  

BIOXIDE solution not only removes hydrogen sulfide, but also prevents its formation. For consistent, effective treatment, Evoqua offers the VersaDose® Automated Dosing Controller and Link2Site® Remote Monitoring Application. Scroll down to learn more.

  • Treats other sulfur compounds - including mercaptans and organic sulfides

  • Prevents corrosion - by effectively eliminating dissolved hydrogen sulfide, which leads to the formation of sulfuric acid 


  • Wastewater collection systems
  • Wastewater treatment plants
