It’s a fact that if there’s a low pH for a certain time it ruins the media. It is amedia that utilizes an oxidation-reduction reaction and filtration process similar to Greensand, but at a much higher level of performance. They usually needs some kind of oxidation or they need  water that already has a lot of dissolved oxygen. If you’re listening to this, you already know this but iron is a serious problem. These media reduce iron, manganese, and hydrogen sulfide in water. There are considerable di˚erences in the It’s now a problem in the US and Canada but we see a lot of iron and manganese problems in Mexico and South America.  We’ve even seen some folks in Europe have this problem and know there are different parts of Europe that have a problem with it, and in Middle East, Asia of course. And now what you get is the media doesn’t ever get exhausted. there’s no chemicals in it. You can also use sodium carbonate. The iron is largely dissolved in the water so you need some way to oxidize it. The high manganese dioxide content produces a much more active and energetic medium — and a much more effective product. So you want to make sure you have something that will work and actually take out the rust that’s accumulated in the filter bed. But it depends on how much iron is in the water, and it won’t work as well if the pH is much less than 7. But, what happens is that when they’re working in the mines and they find a relatively high grade, in cases that we use it it has to be greater than 80% and the average is like 85% pure manganese dioxide, then they set that aside. We talked about the sand and anthracite media, it is not the best option generally for iron treatment especially for homes on standard wells. So the vast majority, I don’t know what the percentage is, but I’ve heard it’s like 97 to 98% of all the manganese is not used in water treatment. Sometimes you’d had used other chemicals to help with the process. It's lighter than Filox, and requires significantly less backwash. The MnO2 based medias are of two kinds: -Manganese Dioxide coated media with a support base- Birm, Greensand Plus, Katalox light etc. It has a little slower reaction time than iron and a higher pH is required. What happens is, the water comes out of the ground clear, but when the iron  and the manganese hit the manganese dioxide media, the iron and manganese oxidize. So that’s one reason it was used a lot. Iron impurity is water is not uncommon in water supplies and storage. So it’s not an effective disinfectant at the levels we’re using. So it’s better to have a chlorinator, it’s the cheapest way, or an ozone system ahead of the iron filter. So if you have an effective iron and manganese filter to reduce the level below 0.05 ppm, it’s not going to cause stains.  Iron and manganese are not really health threats, but it tastes pretty terrible if it’s high enough but some people are affected. MnO2is a granular or sand type of filter media whose application is quite common in a number of manufacturing processes, specially water treatment.It is used in softening well water by eliminate iron, manganese and Sulphur impurities from it. That is, they turn from a dissolved form to a solid form. But when we have it in the water, it’s considered a very weak biocides. It’s cheaper, it’s light, but has a very, very thin coating of this manganese dioxide on it and it’s a bit unstable, you can’t use chlorine with it. Some of the proprietary media on the market include the following: • Ferrosand®manganese greensand produced by Hungerford and Terry • GreensandPlus TMsynthetic manganese greensand produced by Hungerford & Terry • LayneOx So the other type of media that we already talked about is the solid manganese dioxide. But you know, the idea is that, if you have a septic tank, you don’t want to run a bunch of chlorinated water down the septic tank. It is media that utilizes an oxidation-reduction reaction and filtration process similar to … But usually it’s clear water. It might work for a few months and then it quits. The Clack will tell you the operation conditions. But you need to know the flowrate because the manganese dioxide or even the coated type, need a certain minimal flowrate to clean that media out. It’s been used for many years. If you have a very low pH, say 5, in that range then you might be better off injecting soda ash into the water which comes in food grade or potable water grade. So we hear a lot of folks saying “yeah I don’t know what the story is like, I don’t have a odor problem in the house except for the upstairs bedroom that doesn’t get used”, or “I have one part of the house that doesn’t get used but the odor is terrible in that water, what’s the story?” Well it’s because you have iron bacteria living in that pipe happily undisturbed and so by running chlorinated water through the pipes, it can kill that. So there’s ways you can deal with that of course. So if you get a system and you set it up where it only takes out the iron, then you’ll quickly realize that all the rust is gone but now you’ve got black or tea-colored stains in the dishwasher or on sinks or fixtures or in laundry. A lot of times you’ll see specs that says it removes hydrogen sulfide. A wide variety of manganese dioxide water filter media … Katalox Light is the latest German-engineered media, composed of zeolite coated with 10% manganese dioxide. Same with hydrogen sulfide. Very dense media with manganese dioxide coating for superior filtering Filox* is used for removing iron, hydrogen sulfide, and manganese from water supplies. Like if you filled the bathtub and it has a slight tea-colored look to it. It is better to use manganese dioxide because the manganese dioxide is a catalyst. MTM ® (P/N MTM) is a granular manganese dioxide filtering media used for reducing iron, manganese, and hydrogen sulfide from water. The terrible sulfur smell that’s so common. So they both work well, but they have different advantage and disadvantages. This can last years, hopefully they do last many years. You can use another tank of crushed marble or other types of pH-raising filter media in a tank before the iron filter to raise the pH and neutralize the pH. Because the thing is, that iron bacteria are not only a nuisance, but they can create odor. Usually if it’s a tank, say it’s a standard tank for a home, it might be 3 or 4 feet tall or maybe 5 feet tall,  most of this oxidation process will take place right on the top layer of the media. So there are various types of filter media. Pyrolox is an NSF certified natural mineral form of Manganese Dioxide. Media acts as a catalyst, but itself remains relatively unchanged thanks for.
