The city of Raleigh Grasshopper force main conveys flow approximately 7.25 miles before discharging to gravity sewer. The hydraulic retention time of this force main under dry weather conditions is over twelve hours, which causes significant odor and corrosion control challenges. Additionally, this specific force main was designed with multiple 90 degree turns which can cause air pockets that hydrogen sulfide sits in and corrode pipes for long periods at a time. To combat the odor and corrosion within this force main, the City of Raleigh utilized a calcium nitrate product for years with resulting in multiple breakages due to corrosion in the last five years. In June of 2024, City of Raleigh approved a SulFeLox® low hazard iron trial study that resulted in an over 90% decrease in average vapor H2S (110ppm -> 10ppm) and approximately 98% decrease in dissolved sulfides (2.2 Mg/L -> <.1 Mg/L) at the force main discharge over the past 365 days. Also, due to the durational control provided by iron salts, SulFeLox® provided more effective treatment at the grasshopper pump station discharge point even when placed at a pump station approximately 8.5 hours upstream of the initial calcium nitrate feed.
