HOW DOES AN IRON & SULPHUR FILTER WORK?

I have shared various in-depth videos on each system that can be found via the links below, but here's a quick overview of how Iron and Sulphur Filters work. 

  • Air is drawn in through the air intake via an advanced electronic control valve to form an air cap within the top of the media tank.
  • As water is sprayed through the air cap it begins oxidizing the iron and sulphur out of the water, and the media traps the precipitating iron.
  • Every three days the air over media filter automatically backwashes all of the media. The iron, dirt and sediment are flushed from the media and into the drain.
  • Then the air cap is rebuilt before the filter is put back into service to continue to remove iron from your water.


WHAT'S THE DIFFERENCE BETWEEN SYSTEMS? 

For Iron and Sulphur Filter Systems, there are three types to choose from: FOB, FOC and FOK. Let's explore each below.

  1. FOB uses Birm as a media, which is typically successful at removing up to 4 ppm of iron from your water when the pH is over 6.8. Low, barely perceptible amounts of sulphur will be removed too but If you have significant amounts in your water, that sulphur will shorten the life of the Birm media and there will be very little sulphur removed.

  2. The FOC uses catalytic or centaur carbon as the media. If you have significant sulphur and less than 1.0 ppm of iron this is a great choice at removing both in one piece of equipment. Your pH should be over 6.5 for this system to work properly.

  3. Then there's the newest of the triplets, the FOK. When you have up to 7 ppm of iron, up to 2 ppm of sulphur and up to 1 ppm of manganese too, as long as your manganese content isn’t over 10% of the iron content, this is your best choice. Also, an FOK will work great at removing iron and sulphur when your pH is between 6.0 and 9.0 but if you want it to also remove the manganese, you need to have a pH of at least 8.0.



As you can see, knowing your water test results will steer you to the right chemical-free iron or sulphur or manganese removal system for your family.

Video Transcript 

Gary Beutler:

Are you wondering which is the best chemical-free, air over media, iron sulfur filter for your family? They all look the same. Is it an FOB, FOC, FOK? Again, they look the same. What's the difference? I'm going to explain it to you right now.

Gary Beutler:

Hi, I'm Gary the water guy. I simplify water filtration to help you conquer crappy water for your family. So what's the difference? The difference is the media that's inside, and that's actually what the last letter stands for. The B in an FOB stands for Birm or Birm media. FOC, C stands for carbon, actually catalytic or Centaur carbon. K stands for Katalox, so Katalox is the media that's in the FOK.

Gary Beutler:

So which one is the right one for your family? Well, it all starts with a water test. We need to know how much iron you have, how much sulfur you have, and manganese if that's a concern or not. If you don't have a lab that can test your water for you, you can always mail us a sample. I'll put an address in the description down below where you can mail us a sample. We can test it for you, and from there, make the right recommendations.

Gary Beutler:

But first I'd like to explain how these works just very briefly. I have other videos on each one specifically on how they work. But basically what happens is they create a big air bubble at the top, an air cap inside the unit. So how they work is they actually oxidize the iron and the sulfur out of the water.

Gary Beutler:

So when you run your water on an everyday basis, your water is sprayed through that air cap. What that does is it oxidize or brings out the iron and the sulfur out of the water. As the water passes down through the tank and over the media, that oxidized iron sulfur gets trapped in the media. It continues down to a screen at the bottom of the tank and a tube that goes up through the middle, and then it goes onto your whole house, cottage, or cabin. Every three days it backwashes, so it reverses the flow. Then it pushes out that air cap, flushes the media, and then rebuilds the air cap, and puts it back into service.

Gary Beutler:

So all that's fine and good, but which one is the right one for your family? Okay. So depending on your water test results, if you've got relatively high amounts like four parts per million or less of iron, FOB is the way to go. If you have a trace amount of sulfur, it's okay. But if you have higher amounts of sulfur, this is not the right choice for you.

Gary Beutler:

If you have almost no iron, like less than one part per million of iron, but you have higher amounts of sulfur in your water, the FOC is definitely the best way to go. If you have up to seven parts per million of iron, up to two parts per million of sulfur, and up to a couple of parts per million of manganese, the FOK is the way to go.

Gary Beutler:

Now, you have to also consider pH in all this. So the pH for the FOB has to be 6.8 or higher. The pH for the FOC has to be 6.5 or higher. The FOK has the widest band. It'll work anywhere from 6.0 to 9.0 pH. But if you're trying to get rid of manganese from the water at the same time, as removing iron and sulfur with the FOK, your pH has to be 8.0 or higher, which is actually quite high.

Gary Beutler:

So the bottom line is you need to know the water test results to determine which is the right one for your family. To learn more about these systems, how to maintain them, how to winterize, etc., click up here. That'll take you to my next video on the topic, and I'll see you there.
