How Can I Eliminate Odors and Bacteria in My Water?

Having odor problems with my water (rotten egg smell) whats the best best way to handle this? We have a water softner and a small in line carbon filter.

Hello Raymond,

Thanks for emailing.  One very effective and low-cost method of removing odors is to chlorinate and then filter your water with activated carbon. 
A chlorinator completely removes the sulfur odors, and also kills the sulfur or iron bacteria that are often the cause of the odor in the first place.  When the water is high in hardness, a water softener after the carbon filter is recommended. 
The result is clean, clear, odor-free, chlorine-free water throughout the home with very little maintenance required.  Just add some chlorine bleach to the chlorine solution tank every few months.  The system recommended below has no filter cartridges and is completely automatic and self-cleaning.

You can use your existing softener and carbon filter, and just add the chlorinator pump and contact tank below.
Here is more information on these systems:

Chlorination and the Stenner Pump Chlorinator System 

Chlorine is a low-cost and safe method of eliminating odors and bacteria, and it works great in oxidizing iron, manganese and other contaminants in water so they can be filtered out.

Although there are other ways to eliminate microorganisms and odors in water, chlorination is the most commonly used because it is low-cost and effective.  Often combined with filtration, chlorination is an excellent and cost-effective way to disinfect drinking water supplies, eliminate odors, and oxidize iron, and other metals. 

For easy and accurate chlorine injection we recommend a Stenner Pump and solution tank system. The Stenner pump uses liquid chlorine bleach.  The system is reliable, easy to install, and very easy to use.  It can be adjusted to get just the right amount of chlorine needed for the application. 

The chlorinator can also be adjusted so the chlorine levels are very low in the household (similar to city water), or a low-cost carbon filter can be installed to remove any trace of chlorine tastes and odors.

Contact Tank

Contact provides optimal contact time after chlorine, soda ash, peroxide or other water treatment grade chemicals have been injected into the water.  Using a contact tank requires less solution and ensures that the solution injected is thoroughly mixed and dissolved in the water.

 These WellMate Contact Tanks are made of a seamless inner shell of molded polyethylene and are impact and corrosion resistant.  The tanks are high quality NSF/ANSI 61 certified tanks for drinking water.  Inlet and outlet connections are 1-1/4” but can be reduced to 1” or ¾” if needed.
Carbon Backwash Filter Systems

Our Carbon Backwash Filter Systems remove chlorine, tastes, and odors at exceptionally high flow rates with little or no pressure drop.

Unlike expensive carbon filter cartridges, the Carbon Backwash Filter Systems use a bed of high grade activated carbon to filter out chlorine, chemicals and sediment.  With these systems the carbon is backwashed and rinsed clean automatically, meaning there's no need to change short-lived filter cartridges, and no problems with pressure drop from clogged filters.  The
carbon media typically lasts for 3 - 5 years and is easy to dump out and change.  Save hundreds of dollars over expensive filter cartridges and enjoy great flow rates with little or no maintenance required.
Softener 7000-SXT
Enjoy scale free fixtures and appliances with soft water.  No more dry skin or dry hair caused by excess minerals in the water!  Save money by using less soap and laundry detergent and extend the life of clothes, water heater and appliances with soft conditioned water with the Fleck 7000-SXT on-demand softener.

Well designed and reliable, the Fleck 7000SXT Electronic Meter-Demand Valve provides larger 1-1/4" internal ports for the best flow rates and least pressure drop, making this valve perfect for use in larger homes with 1", 1-1/4", or even 1-1/2" plumbing.  No matter what size home you have, there is less pressure drop through this softener than other residential softeners. 

The new 7000-SXT softener uses less salt by monitoring the amount of water used in the house and regenerating only when necessary.  If there is a power failure it can keep the correct time up to 48 hours.  Also, the system keeps time electronically, so the drive motor only runs during regeneration, saving energy and lasting longer than other softeners with standard timer motors.
