Best Solutions for Bad Well Water Odors

Hello there,

I have well water with a really bad sulfur odor. I am looking for a solution to fix this problem. We have a water softener, which does not help.  We tried a carbon filter for the house, but it only lasts a couple of weeks.  If we leave the home, when we come back the odor is really bad.



For treating odors one very effective method of treatment is by way of chlorination injection, a Contact tank for appropriate retention time, along with a backwashing Carbon filter in order to catch the oxidized elemental sulfur.  Odor can come from naturally-occurring sulfur in the well water or from bacteria that release hydrogen sulfide gas. 
A carbon filter alone without pre-chlorination does not work well, because bacteria can grow in the carbon and carbon alone will not last long for removing sulfur.  Combining chlorination with a carbon filter though works great.
The following method uses chlorine injection with the use of a Metering Pump along with a Contact Tank which provides a couple of minutes to destroy the odors along with oxidizing the small amount of Iron from the water.  Once this process is complete the water is simply filtered by a Carbon filter which removes residual chlorine along with improving tastes and odors.

Please see below for images, product links, pricing on each component, as well as other pertinent information for this option.  This system will take care of the odors as reported so as to provide clean, non-staining, odor-free water for use in the home.

I’ve sized the following to treat a home with up to 3 – 3.5 bathrooms however smaller and larger sizes are available.

Chlorinator Package Precision-24 + 15 Gal Solution TankPrecision-24 Metering Pump with 15 Gallon Solution Tank:                     

Extremely versatile pump comes in either 115 or 220 volt so as to be wired to come on whenever your well or pressure system is energized.  Works with well water flow rates from 1 – 50 Gallons per Minute (GPM).

Output rating:  0.1 – 24 Gallons per Day (GPD).  Pressure rating:  Will inject into lines with up to 110 PSI.  Digital speed adjustment allows for quick changes to pump output.

Carbon Filter 5900e 1.5 CFCarbon Backwash 5900, 1.5 cu. Ft. 115 Volt:                           

All the filter media you need for the system is included.  Excellent for use in removing residual peroxide from water once injected, along with improving overall tastes and odors.  Long lasting & durable this Coconut Shell Carbon typically lasts for 4 - 6 years and is easily replaced.

Much longer life and higher flow rates than standard carbon. Unlike carbon cartridges which can trap sediment and dirt causing pressure drop these systems automatically backwash out trapped sediment alleviating pressure drop.  Allows for a maximum flow of 15 GPM which is perfect for a home with up to 3 – 3.5 bathrooms.

Dimensions:  10” Diameter x 61” Tall with control valve.  ¾” or 1” pipe connectors and bypass is included.  We also provide full installation and start-up guides directly to you and are available for Tech-support.
