ABSTRACT:
A method of reducing sulfide odors in wastewater collection and treatment systems. The method includes adding nitrate ions in the form of a controlled release composition and microbes to the wastewater effective to reduce hydrogen sulfide levels. The controlled release composition can be in the form of a water-in-oil emulsion. The microbes can be aerobic and facultative Bacillus species.
