Use of peroxide for treating sulfur in a lift station
asked 31 July 2017 asked by Asma (420 points)
You want to reduce it or oxidize the sulfur?
You can inject the waste stream with several additives to reduce the sulfur ferric salt, bioxide, peroxide, certain bacteria types (see a company called BioScience out of Allentown PA.), etc. Chemical feeds work (as long as you dose correctly depending on your sulfides ppm) you will have the occasional spike regardless during low flow times. I would however recommend that you look at A.O.P. Advanced oxidation process which is pumping O-Zone without nitric oxide directly into the way stream… It will oxidize everything in the waste stream including the sulfides and reduce your FOG, BOD, TSS, H2S and more. If you put certain systems into a lift station you'll eliminate FOG cake and reduce H2S dramatically for a fraction of the cost of chemical feeds. See A company called Eganix out of Berkley, MI Good luck
Thanks for your help!
no problem... anytime, let me know what route you end up taking please and your results... do you know the exact source of the sulfur? Levels?
you are only going to waste your O3/H2O2 on easy biodegradable organic matter. Maybe you formulate your question a bit better if you acutally want to have a good answer.
Have you done a sanitary survey? Where is it coming from? Length of pumping to the problem lift station? What other options have you tried or considered? Chemical injection is a costly alternative.
