That’s the chemical thing, I’m going to take that and instead I’m going to made it with a little bit of ammonia. That’s what the aiming is. So you’ve got clore and then, I mean I’m going to hook that up with an Nh four and it gets rid of it, gets rid of the, uh, gets rid of that hydrogen off of there. But what it does, it makes it a little less reactive and it makes it last longer in the water and there’s a couple of benefits of that. I can use a little less concentration and it’ll get out and do a residual all the way through the plumbing system better.

Speaker 2:                           00:32

It’ll be

Speaker 1:                           00:35

safer because I don’t have to use as much of it. And it’s less expensive too because I don’t have to use as much of it. Bree municipalities, I can dose it into the water and I don’t and, and use less of it. So there’s a bunch of different things that chloramines aren’t beneficial for voc. Volatile organics. I’m teflon that made everybody here knows what Teflon is, right? Well, manufacturing of Teflon put certain things into the water while manufacturing a bunch of different things as we find out, as we become more and more attuned to what’s in the water. Um, MTB, he was a fuel additive. Um, pls are the, some of the things that we use in manufacturing for certain plastics and polymers, these are organic compounds that have that get back into the water system and are now part of the water supply in the groundwater supply and in the surface water supply, they get back into the system.

Speaker 1:                           01:31

So that’s what these are. And they can be toxic or they can be dangerous. Carbon can remove, can be very effective at voc removal. Heavy metals like mercury and other things as well. So that gives you an idea. Carbon is this outstanding filter for a variety of different things. Carbon is not a new material. Activated Carbon has been used for a long time. The ancient civilizations realize that if they charged, if they put bits of charred wood in their water supplies and the streams, it actually clarified the water a little bit. So they understood that that activated carbon had a bunch of benefits to it for their water. The insides of barrels for a lot of different alcohol aging are charred on the inside of the barrel because that activated carbon surface on the inside of that barrel can do a lot of the filtration and a lot of pulling off of the bad flavors and odors that that’s on the inside of the stuff that’s in that barrel.

Speaker 1:                           02:41

So that’s why they charged the insides of those barrels. What do we get? So with Pentair we make activated carbon filters. Alex right there in front of you are a variety of different filter types, right? Every one of those filters that’s in front of you and it hasn’t activated carbon component to it. We’ll get to that in a little bit. All of those filters that are, that are in front of you though are activated carbon filters and the. What we use for our carbon filters is a couple of different materials. Primarily the thing we use the most of is cold.

Speaker 1:                           03:19

We also do make filters. Probably the second most common item we use as coconut shell, but we also do make some carbon filters that have a wood base carbon as well, and you can do any one of these. Fluoride, what do we put fluoride in the water for? Cleaning, washing teeth, teeth brainwashing. Yes. I hadn’t heard that one before. I’m fluoride in the water. Also has the ability to be maintenance for the pipe, the walls of pipes as well, so fluoride compounds in water will actually help men. The insight surfaces of pipes and infrastructure. I believe that that was the primary reason why we started putting fluoride in water and then afterwards they found out, hey, we’re getting less cavities and people that drink this stuff too. It might be good for the enamel surfaces of teeth as well, so that’s sort of, I believe that they became activated carbon.

Speaker 1:                           04:26

Why do we use different materials when you use different materials here? I’m going to go down here. When you use different materials and you activate that carbon, so let’s think about this for a minute. When you think of coal, you think it’s something that’s like a hard rock, black, hard surface item, right? When you think about what it’s hard surface coconut shell, if you think about activated carbon as a component, you start with that carbon. We all have carbon in us. Every living thing has a measure of carbon in it. When I activate it, what I’m doing is I’m taking, if you think about it like a kernel of corn and you submit it, the pressure and you submitted the temperature, high temperature, what happens? Pops it pops. That’s what activates. So you’re activating that popcorn. You’re really not eating popcorn and you’re eating activated pot for.

Speaker 1:                           05:23

So that’s what you should just keep that in mind because the popcorn is really that colonel, right? Well the wood and the coconut shell and all, and Nicole is your popcorn. When we activate it, we submitted the high temperature, we submitted to some pressure in the absence of oxygen and it pops and what that popping does. When you think about that popcorn, the activated popcorn and you look at the surface of it, it’s got a bunch of crevices. It’s got a bunch of places. It’s got a lot, bunch of more surface area, right? It’s lighter, it’s porous butter flows through it nicely. What we do with activated carbon is we take that same kernel, we take that same chunk of coal or whatever and we pop it and we make it porous and we put crevices and poor’s and all kinds of things and we’d give it a much more effective filter capability.

Speaker 1:                           06:13

I can fill. I can fill a tank with popcorn. I can fill a tank with popcorn and run water through it and I’m going to filter some stuff out. Bricks, cars, birds, stuff like that, right? So I’m still going to have a filter. It’s just not going to get me down to a very small or very fine size. Once I activate that popcorn and I fill a tank up with activated popcorn, now I’ve got a bunch of crevices. I’ve got a bunch of places that stuff can get caught up in. I make a much more effective filter, so that’s what I’m going to do with my carbon activated. When I activate, when I submitted the temperature and high pressure, what the surface does is it creates poor sizes in that carbon and that’s not, that’s not jumping a big bridge, right? If I take a coconut shell and I and I burn it chart and then activated the, the nature of that’s probably going to be a lot different than coal or wood. Well, typically the pore sizes of wood based carbons are very large and we call that macro or so very large. Um, coconut shell tends to produce pore sizes that are very small or micro fours. The reason we use coal, lignite, anthracite, things like that as our primary source for coal are for activated carbon is because it produces poor sizes that are right in the middle. And that just

Speaker 1:                           07:41

gives us the best ability to apply to the most applications. So that’s why we use colon most of our products is because it gives us medium sized pores. It’ll address the most issues on its own. You want to think about pore sizes and what that works as, um, this is kind of a good visual of what that looks like. I want to create pores that will catch whatever contaminate it is inside of it and lock it in place. Okay. Carbon works by nature of what’s called adsorption.

Speaker 1:                           08:20

It’s porous water flows through it, so I will catch them things inside of it just by adsorption, just holding it inside like a sponge. But really what I’m doing when I’m doing chemical filtration is what’s called adsorption, making it sticky. Another name for Glu is adhesive. I want to add here things to the surface, so that’s when we do adsorption. I’m going to create a lock and key type of situation and the reason I want different pore sizes is because small pore sizes lockups, small contaminants, larger pore sizes lock up larger contaminants. So what are some of those things? Small contaminants, small tiny niche. We’re talking molecular level stuff, atomic level things, well, volatile organics like try halo of methane and things like that. Gases very small items are going to be best addressed with small pore sizes, so that’s why if you’re taking things out like I’m voc that are in the water contaminants that are in the water, most often what you’ll use is what’s called coconut shell, carbon filters and you you’ll find in the in the handout and then the partner center, and then the guy. We have coconut shell carbon. Most of the time. Those filters are used for very fine contaminants like larger pore sizes are applied for larger chains of molecules you ever have. Is anybody ever heard of a Tannen? You guys ever heard of Tannins? You drink wine and make your drink red wine.
