Aeration System vs Chlorination System Against Sulfur Odors

Hello Mr. G,

Thank you for contacting us yesterday about your sulfur odor issues. L
ike we talked about, it would be nice to have the water analysis on hand in order to know what to recommend to you. If you’re interested, here is a link to a test kit that we offer that covers the basic mineral content of your water: 

Basically, it’s a two-part test kit.  It includes testing at DIY home testing for iron, pH, manganese, hydrogen sulfide, etc… and it also includes two sample bottles for testing at our lab.  The lab test is quite accurate and gives results for hardness, manganese, iron, TDS, and pH.  Between the home testing and lab results, we should have everything we need to make a great recommendation for you on how to remove iron and prevent odor and staining problems.  

In the meantime, I can go ahead and make two separate recommendations:

The first option for odor is a self-contained sulfur filter which uses air injection to oxidize the sulfur out to then pass the water through a mixed bed of filtration media designed to remove odors from water.  This is an automatic backwashing system that rinses out the media once two days in order to keep the media clean and maintain a head of air for the oxidation.

The second option uses chlorine injection with the use of an injection pump. This provides extra strength oxidation for strong odors and high levels of iron and manganese (which can be linked with sulfur odors).  This system also provides disinfection, providing you with clean water, void of bacterial contamination.  The chlorinated water would then feed into a contact tank to provide enough time and contact for the solution to react with the sulfur, iron and bacteria in the water. To remoce oxidized particulate matter, it could go through a non-backwashing carbon filter. The carbon backwash filter can handle much higher levels of odor and iron, but it is more expensive and requires more maintenance, so that’s something to consider.

Option One: Aeration System

Air Charge Sulfur Filter 5900– 1.5 CF Size
Air Charge Sulfur Filter 5900

Iron / Sulfur Air Filter Includes:
·         Eliminator Plus 115v control valve
  • ¾” pipe connectors with bypass valve
  • 1.5 Cubic foot of Centaur carbon filter media

  • Filter tank diameter: 10 inches
  • Height including control valve 61 inches
How the system works:  The AIO air filter maintains an “air pocket” in the top of the tank while the system is in service.  As water passes through the air pocket, iron and sulfur are oxidized.  The Nelsen AIO filter media bed then removes the oxidized iron and sulfur from the water.  Additionally, dissolved oxygen is added to the water.  By utilizing a patented piston in the control valve, the AIO Sulfur filter is able to put the whole oxidation process inside one tank, keeping maintenance costs and down time to a minimum.

Option Two: Chlorination System                          
 Hydrogen Peroxide Proportional Flow Well Water J-PRO-22:

Can be either 110 volt or 220 volt plug; can be hardwired to a pressure switch to come on with a well pump.  Works with well water flow rates from .5 – 89 Gallons per Minute (GPM)

Pressure rating:  Will inject into lines with up to 100 PSI.
