Use of sodium nitrate injection to prevent H2S in wastewater system
Use of sodium nitrate injection to prevent H2S in wastewater system
(OP)
Specifically in a 10-12" force main with 360,000 gallons per day avg. flow in approx 18,000 linear feet force main. Samples reveal over 200 ppm H2S (maxed out my meter) and PH of less than 2.

H2S can be oxidized but kinetics are slow, hours? Something like copper sulfate can be used. H2S will react to precipiate copper as copper sulfide which can been removed by conventional solid/liquid separation. H2S is consumed in the process.

The only refernce source I can give you that might lead to some useful information is a Society of Petroleum Engineers (SPE) paper # SPE 49152, Microbial Water Treatment: An Alternative Treatment to Managing Sulfate Reducing Bacteria Activity, etc by Cassinis, Portwood and Farone.
Good Luck!
