Liquid chlorine, when added to any water source, will work to oxidize and kill everything it can, including iron, manganese, sulfur, tannins, and some bacteria. After oxidizing and killing what it can there will only be a residual amount of chlorine left, telling us that the chlorine has done it's job. Municipal water treatment plants commonly use chlorine as their disinfectant of choice which is why most city-treated water sources can taste or smell like chlorine from the tap. In well water applications, chlorine is our choice of oxidant to effectively treat a large list of contaminants with one convenient system. The key to proper chlorine oxidation is contact time, where the chemical can make contact with the oxidizable matter long enough to react with and neutralize it. Once these contaminants are neutralized, they are easily removed by water filtration equipment.
What can the Iron Max Plus do?
The Iron Max Plus is designed to treat the three types of ground water iron: ferrous, ferric, and organic, as well as high concentrations of manganese (Mn), hydrogen sulfide odors (H2S), sulfur reducing bacteria, and tannins. Ferrous and ferric iron is very common in well water and can easily be removed without the use of oxidizers or chemicals. Organic iron, also known as iron bacteria, and sulfur reducing bacteria are two less common contaminants that cannot be treated with typical filtration and require an oxidizing agent to effectively remove them from your water. Note these bacteria are not health hazards like E. Coli or Total Coliform, which require ultraviolet light disinfection. These bacteria are minor nuisances that may cause foul odor, staining, and slime build up in plumbing and fixtures.
How does the Iron Max Plus work?
The first and most important part of the Iron Max Plus is the chlorine solution tank, which is plumbed right after your well and before your pressure tank. This 45 gallon solution tank is filled with a solution of water and chlorine for oxidizing iron and sulfur bacteria. This solution tank includes a small injection metering pump that is mounted on top of the tank with a pickup tube submerged into the chlorine/water solution. The metering pump is wired to the switch side of your well pump switch so that it is only activated when the well pump is activated. When water from your existing bladder tank is depleted and the pressure drops, the well pump and the metering injection pump are activated to refill the tank. The injection pump feeds the proper amount of chlorine solution into the flowing stream of water with the use of a tee injector fitting that must be installed before the pressure tank.
This chlorine solution thoroughly mixes into your well water and fills your pressure tank with the appropriate concentration of chlorine to oxidize iron, iron bacteria, manganese, sulfur gas & bacteria, and tannins. Your existing pressure tank serves as a contact tank to ensure efficient contact time with these contaminants, which eliminates the need for another piece of equipment! When there is a demand for water, treated water from your pressure tank will then enter the Iron Max system plumbed right after your bladder tank, effectively removing the oxidized contaminants. Our free post carbon filter is installed after the Iron Max to remove any residual chlorine left in your water, so you don't even know it was there!

What exactly does the Iron Max Plus system remove?
The Iron Max Plus uses chlorine to oxidize high levels of iron, manganese, hydrogen sulfide gas odors, tannins, and iron and sulfur bacteria. After oxidation, the Iron Max filters out high levels of Ferrous and Ferric Iron up to 30ppm (mg/L), Manganese up to 3ppm (mg/L), Hydrogen Sulfide Gas up to 7ppm (mg/L), Tannins up to 5 ppm (mg/L), as well as the oxidized iron and sulfur bacteria. The addition of an oxidizer such as our chlorine injection system enhances the Iron Max's filtration performance, which leads the Iron Max Plus package to be a very effective well water treatment system. After the Iron Max the included post carbon filter can be added to remove the residual chlorine for improved taste and odor.
Is there any routine maintenance involved with the Iron Max Plus?
The only maintenance involved with this system is occasionally adding chlorine solution to the solution tank and replacing the carbon cartridge, typically every 9-12 months depending on water usage. The specialized Iron Max filtration media will need to be exchanged approximately every 8 to 10 years depending on water chemistry and usage. This is easily accomplished with the use of a wet & dry vacuum which you use to vacuum out the old filtration media from the top of the filter and then you fill the tank with a fresh bed of media.
