Chlorinate and Filter to Remove Iron Bacteria for Good


Got your name from our neighbors, their system is working good.  We have odors and a small amount of iron.  However we have slime in our toilet tanks, and we are sure its iron bacteria.  We want to chlorinate and filter, what do you recommend?   I already have a softener, which is doing most of the heavy lifting on this water now!

Dear Gary,

Thanks for emailing.  To treat the Iron and Iron Bacteria I recommend chlorination injection followed by a Contact Tank for necessary retention time, followed by filtration by a Pro-OX Iron Filter, and finally treated by your existing Water Softener. 

How this application will work is the chlorine (Clorox) bleach mixed with water is injected whenever the well is on, once injected the 80 gallon contact retention tank allows for enough contact time for the chlorine to react with the contaminants and fully oxidize for filtration.  The Iron filter then taking out any residual, oxidized Iron/Manganese/Odors.  As the Iron filter media will thrive with the bleach, and is used to further enhance performance, typically no residual chlorine remains in the treated water. 


The Precision-24 self-priming chlorine pump systems are easy to install by anyone familiar with basic plumbing and very easy to maintain yourself.  Settings for the pump will be provided as well as the ratio of Clorox : Water to be used.

Pro-OX Manganese Dioxide media is an NSF Certified natural high purity mineral that is used for removing iron, hydrogen sulfide, and manganese from water supplies.  These media utilize an oxidation-reduction reaction and filtration process similar to Greensand, but at a much higher level of performance. 

Pro-OX has a much higher surface area and is much more porous than Greensand, but it lasts much longer (usually between 10 years, compared to around 5 years maximum for Greensand).  Pro-OX can also handle higher amounts of Iron/Manganese, and Iron Bacteria. 

The following will show images and product links for additional information.
