So that’s the big difference in it. And by chlorination or aeration or ozonation, I mean an automatic or continuous system that injects a tiny bit of chlorine before the filter system. Manganese Dioxide (MnO 2) MnO 2 is 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. Okay well, I’m going to wrap it up. there’s no chemicals in it. Iron and manganese, in excess of the suggested maximum contaminant levels (MCL) may result in the discolouration of water causing staining of equipment and final product; it can also give a metallic taste to water or to manufactured foodstuffs. Now there are situations where you can use the manganese dioxide media without any prior aeration. The thing is it doesn’t really remove hydrogen sulfide on its own for very long, unless you use an oxidizer. Specifically, manganese dioxide media which is the probably the most common type of filter media used for iron and manganese removal. Manganese dioxide is a natural filter media that effectively removes iron, manganese and sulfur odor from well water.   There are different types of manganese dioxide filter media and Gerry discusses the advantages of the various kinds as well as discusses what to look for when using this filter media. The high manganese dioxide content produces a much more active and energetic medium — and a much more effective product. 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. MTM ® (P/N MTM) is a granular manganese dioxide filtering media used for reducing iron, manganese, and hydrogen sulfide from water. 8, 10, 12 gallons a minute is pretty common. Developed By. It needs a higher flowrate but it’s not huge,like 2 or 3 time,s but it’s somewhere like 30% higher flowrate than say a greensand or other type of coated media. 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. Its not adding lead or arsenic into the water, or some other weird stuff. We buy ours from Pro-Ox.  They’re one of the largest manganese producers in the world and the vast majority ofthe manganese they find is not suitable for water treatment and that’s true with other mines as well. So there are various types of filter media. Need assistance? It might work for a few months and then it quits. Then if you have a one tank system then you’ve got to add more calcite to it pretty regularly. 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.

Get contact details and address | ID: 6982538248 These 3 products are identical and share the following characteristics: Pyrolox Filter Media Specifications So better to remove it and fortunately it’s cheap and easy to do, so most folks do that. Its active surface coating oxidizes and precipitates soluble iron and manganese. So chlorine has advantage that it kills iron bacteria and it works really well with manganese dioxide. Most people don’t have acidic water but we have quite a few people with acidic water. It’s been used for many years. They metabolize the iron and manganese for their cell walls and in the end you end up with a stringy mass. Book a Phone Call Appointment with one of our Water Specialists. Like if you filled the bathtub and it has a slight tea-colored look to it. This granular filter media is black in color and is extremely dense. So it’s better to have a chlorinator, it’s the cheapest way, or an ozone system ahead of the iron filter. 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. You can find solid manganese media of a much lower purity (usually less than 50%) in some other countries, which is why Pro-OX is generally seen as the gold standard in iron filter media. Manganese dioxide is the active ingredient of all leading iron/manganese reduction systems. It’s counter-intuitive because we have peroxide and sometimes you put it on your skin to clean a cut or whatever so you think , “Oh it’s going to kill bacteria”. It’s a pretty low level and manganese requires more oxidizing power. Ozone is really good except for the price. And one way to figure that out is if you can measure the ORP. Filter column experiments employed both new anthracite coal and sand as well as oxide‐coated media obtained from three full‐scale water treatment facilities. How do you regenerate manganese greensand filter media just purchased prior to placing it into service? Okay so we talked about oxidation but now, what type of filter media to use. If there’s hydrogen sulfide in the water, the rotten egg odor, it doesn’t work well for that. I appreciate the emails and feedback I’ve been getting and if you’re using iTunes and you’d be so kind, it’d be great to if you went over to iTunes and rate it and maybe left a short review of the podcast. So when there is a tiny bit of dissolved oxygen in the water, and the iron and manganese in the water come in contact with the manganese dioxide, you get that catalytic reaction and the iron and manganese is filtered out of the water. But it needs something, these type of coated systems really don’t work well on their own without any type of oxidation. Generally for homes we do recommend aeration because over time your water might change. It doesn’t fail quick. Manganese Dioxide Filter media containing 80% manganese dioxide and 20% filter sand is used for the removal of ferric iron and manganese usually from well water or borehole supplies. But the chlorination and aeration are relatively low cost ways to go. They don’t realize they also have manganese too. If there’s enough oxidation in the water, then when the hydrogen sulfide and water flow through the manganese dioxide media, it basically converts the hydrogen sulfide into an insoluble particle that then gets trapped in the media and the odor is gone. The idea is that you just want to increase the potential of the water for oxidation so when it hits the manganese dioxide media, a catalytic reaction takes place right in the media and boom, you get all these great formation of iron floc happening right in the media. The silica sand core of GreensandPlus allows it to withstand waters that are low in... Read more → That again is the standard for that is anything over .05 ppm. Hydrogen sulfide is oxidized to a sulfur. That’s what you want to look at, you want to make sure the media in the filter tank is very uniform. In today’s episode, our host Gerry Bulfin, a water treatment contractor and WQA Certified Master Water Specialist discusses iron filter media, particularly manganese dioxide filter media for removing iron and manganese from well water. But generally, the Pro-OX, the manganese dioxide media, this type of media will work better than just the cartridge because the iron will pass right through it. 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. There are a few types of media in which the primary ingredient is manganese dioxide. 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. And then some folks with bigger homes or they have some agriculture used, they have higher flowrates. And so that’s a sign of a high quality media, it’s all very uniform in size. But generally it’s more of an aesthetic issue. Gerry Bulfin here again. It strips the coating. Say you’re using an air injection iron filter, you’ve got your manganese dioxide filter, it’s working great, it’s taking out all the iron, Then once or twice a year or maybe more if you have a really bad problem, you sanitize the pipes and the well if you can with chlorine bleach. Several different types of manganese dioxide coated filter media are used. Starke Filter Media has been a leading manufacturer for Manganese Dioxide in the country. You almost have to use an oxidizer if you’re using any kind of manganese dioxide media, so chlorination is good. Below 7 is considered acidic. And what it is, is that the media is porous. Please share your details to download our products specification. Pyrolox functions as a catalyst, but itself remains relatively unchanged. You can look at it this way, it primes the water or increases the oxidation capacity of the water. So there’s many different kinds of filter media, and that’s what we are going to talk about. Aeration can work too but you have to have the pH up higher, I’m going to talk about pH in a minute here too. And the solid manganese dioxide media where it’s a solid granular like a solid chunk of the manganese dioxide. While iron itself is important for health, it acts as a secondary contaminant in water, causing problems while making tea or coffee and cooking vegetables. And I know I’ve referred to chlorine much of times and this is covered in the other podcast episode on chlorination. So as I was talking about how the performance of the media is directly related to the purity of the manganese dioxide and the porosity of the granules and the level of highly active sites on the structure. 8. These media reduce iron, manganese, and hydrogen sulfide in water. For reduction of iron, manganese, and … It removes rust particles out and then the filter media is good to go for another run. But usually it’s clear water. So that just means that they’ve been able to put a coating of this manganese dioxide material over some other kind of cheaper and lighter substrate. Some of the coated media can fail within a few years. I wanted to mention tannins too. GreensandPlus™ is a black filter media used for removing soluble iron, manganese, hydrogen sulfide, arsenic and radium from groundwater supplies. I’m mainly going to talk about manganese dioxide, but the first  we’ll talk a little bit about oxidation because it relates to the type of manganese dioxide you might use. So the higher the porosity of the solid manganese dioxide media, the better it is. But essentially if you can raise the ORP over 200 millivolts, then the water has enough oxidizing capability on its own and it doesn’t necessarily need a chemical regenerate or aeration ahead of it. ft. ) Ground shipping ( 48 States, not Alaska, Hawaii or Puerto Rico ) is figured into item price. Pyrolox filter media sold in either 0.25 cu.ft. So for homes and small communities it’s not used that much, but it’s cheap. The disadvantage is it’s heavier than that coated type. 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. I know like for instance in some countries, you find it in like India and in China, the solid manganese dioxide has very low purity. Most systems using only 60 pounds ( 0.5 cu. So there’s ways you can deal with that of course. If you have acidic water, you want to correct the acidic water anyway because you don’t want acidic water running into the home where it can corrode fixtures and fittings even if you have PEX pipe, you can still get corrosion problems on your water heater, etc. All it is, is just they mine this pure manganese dioxide ore and then they grind it and grate it and wash it so you get a very high quality filter media. So anyway it works great if you have iron, if you’re looking for iron removal with a manganese dioxide filter. After it goes through the manganese dioxide, it’s either gone or it’s really low where you can’t smell or taste it. Manganese dioxide coating on the filter media acts as a catalyst for the oxidation and reduction of iron and manganese. A lot of times you’ll see specs that says it removes hydrogen sulfide.
