How to Treat Well Water For Iron Bacteria and Rotten-Egg Odor with Chlorine Or Hydrogen Peroxide

My question is: I have well water that is high in iron (4.0 ppm) but I also have iron bacteria.   There is a slight odor of sulfur as well.  Should I use chlorine, or is hydrogen peroxide better? What is the difference?

If you are concerned about bacteria being in the well water, we recommend adding chlorine with a metering pump which would feed into a contact tank.  Inside the contact tank, you are able to have disinfection occur.  The benefit of adding chlorine is that it will also help with the iron filtration as well as extend the life of the filtration media.  To remove the iron a heavy-duty MangOx filter would work well. It would be able to filter out iron that has been oxidized by chlorine.  The result of these two systems together would be disinfected water without any iron staining.

Hydrogen peroxide can be used by this same system.  The benefits of using peroxide are that no chlorine byproducts are added to the water.  For example, chlorine bleach is sodium hypochlorite, so you are inadvertently injecting some sodium into the water as well as chlorine.  Many people use regular household bleach which can contain harmful trace metals and chemicals, whereas hydrogen peroxide breaks down into oxygen and water, and leaves no unwanted trace elements.


 

Metering Pump & Tank: 45MHP-10 Stenner Pump with 15 gallon heavy-duty polyethylene solution tank;

Pump output 0.5 to 10.0 gallons per day (1.9 to 37.9 liters per day); voltage 115 or 220V; 60 Hz. (NOTE: Voltage should match that of well pump so that it can be wired to switch on only when pumping water) This is a complete system that comes with everything you need: solution tank; metering pump; tubing; fittings; and injection check valve.
