Options of chemical dosing for sulfide control
The following options are available:
- Oxygen: Oxygen is used as an oxidant, which oxidizes the sulfide already
present in wastewater and prevents formation of sulfide downstream by
maintaining aerobic conditions. - Nitrate
- Ferric chloride
- Magnesium hydroxide
- Free nitrous acid
- Caustic
