That’s right, so here’s the thing that gives red wine. A lot of it’s character is tan color chains that are in the water cannons in water and and usually where you gonna find hands in water when I mean by tans is this, if you ever run a, a, a, a tub for a bath, you ever draw a bath and you pour water into a big white tub. A lot of times the tinge in that water can be yellow or an amber or a green color. Those are probably the most common. Um, there are places in the United States where that happens. Florida tannins are very common coastal areas. I’m sure there’s places run like Houston and all that down the Gulf shore where it’s not unusual for water out of the ground and have color in the water. I’m in Portland. Portland had around Oregon. There’s actually a rain forest that’s on the coastal area there.

Speaker 1:                           00:52

Will, they get a green can and that’s in the water because of what’s in the ground and water and where it goes. And how would it would it settles down through. It’s not going to kill you. It’s not going to hurt you, it’s just a chance like bathing in one in a manner of speaking really, really light wine like a rose, a sip on your bathroom online, but the thing, here’s the thing, those color, those tenants are often large chains of compounds. Okay, so large poor activated carbon becomes a very effective means of removing color out of water because of the typical nature of those color chains. Carbon can also, you know, sure, I can use coconut shell carbon to remove color out of water and I can use wood base to remove like a trihalomethanes out of water, but if I don’t lock it in, what happens is is it’s called sloughing off. It becomes a

Speaker 1:                           01:53

subject to being knocked off by whatever the next thing that comes along is it and what can happen in the water supply for the customers. This, the carbon filter works for awhile, really great a day, a week, whatever it is, a month, and then it gets to a certain point where it’s loaded up and then instead of just stopped working, it’ll actually just start breaking free. A lot of the stuff that it collected and sloughing off a lot of contaminants because it’s not locked in place like that, so a dre addressing your contamination with the kinds of carbon and it just works out best. Again, that’s why we use carbon. That’s what we use coal base with the metal parts, with the medium sized pores as their primary source, so it gives us a better chance to lock in the most contaminants. Does that make sense? And what’s that process called? What kind of is kind of absorption? Adsorption adsorption

Speaker 1:                           02:48

carbon adsorption carbon doesn’t actually remove chlorine from the water. Okay. Carbon doesn’t remove chlorine from the water. What it does is it breaks out that oxygen from the hypochlorite so that that that ion, when you smell a pool, when you smell that chlorine bleach smell, that ion is what’s causing that. And if I pull that oxygen out, if I run this over the surface of carbon, that car and pulls that oxygen out and it creates carbon with the oxygen and the hydrogen and chloride. So what I’ve done, I haven’t removed the flooring from the water, would I have made, is a little bit of half of what water is hydrogen and then I made put chlorides in the water and chlorides don’t have that pool smell. So cl two is what? This is usually going to occur. It naturally. So what I’ve done is I’ve made. I’ve just taken a taste and odor out of the water. I haven’t removed the chlorine, I’ve just made it more palatable for consumption. That’s how. That’s how that adsorption how that effect is. That’s what chemical filtration is. A lot of times it’s not removing it from the water, it’s just changing the nature of what it is. So that makes it better for the experience.

Speaker 2:                           04:12

Cool.

Speaker 1:                           04:13

Hey Bill, what’s up? What is the effect on that? On people that have a concern with the health effects of the. Okay. And by the health effects you to where you talking about like people who do the research about what chlorination and chlorine free chlorine in the water, the that I on the Hcl, the hypochlorite is the primary component of that. So we’re rendering that. We’re breaking that apart as well. Okay. There are some. There are some people though that have lower tolerances and have concerns about chlorides though as well. So this is happening in really small amounts. Sure. But there could, if you have a particular concern about chlorides in the water, that would be something that you’d want to be probably you’d have to get down to a finer level of remove it, but it’s the hypochlorite that would be the worrisome part of that.

Speaker 2:                           05:06

Okay.

Speaker 1:                           05:08

And it also, you know, hypochlorite is what if you’re ever taking pumps apart or if you ever taken plumbing apart and you take out the rubber seals and those black gaskets and everything and after you handle them, your hands are all black. That’s that. That’s that bleach that’s breaking down and oxidizing that rubber. So you’re making the water less reactive with that as well when you’re doing that carbon filtration, breaking down plastics and rubbers and so forth. So when you do get down to a finer micron takeout chloride, is that actual installation or is that another chemical process? Now you’re kind of breaking in to the other side so that, so now, because we’re talking atomic level joy, we’re talking actually parts of the water and at an atomic level and the only way that we can create a barrier to stop that from happening is getting tight, that we’re going to have to make a membrane that is selective from what it left when the passes

Speaker 2:                           06:02

through it. Yeah. I like the foreshadow. That’s good.

Speaker 1:                           06:12

Any other questions? So that’s chemical filtration.

Speaker 2:                           06:17

Anything

Speaker 1:                           06:22

they do, we talked about that. I’m glad that we’re revisiting because now reminds me to go back to those filters. So every one of those that Alex has in front of them are carbon filters. Reach out and grab one of those. I don’t care which one. Bad choice, bro. Dude, that’s the high end one. Why did you grab that one? The bigger one. So that one. What is the. What’s the micron rating on that one else? What’s the micron rating going? 400 point five. And what can we catch? And a point five micron filter all the way down to what is it rated for? Yeah, with some of the things that we’ve talked about, contamination, mice, cysts, cysts. So as a physical filter we can get all the way down to think here so we can get all the way down to cis size, an actual living microscopic organisms in the water. When you lift that up, go ahead, pick it up again. Now what I’d like you to do is pick up one of those other ones that are the same size. What’s that? So what’s. What’s that one? What’s it rated at? A 10. And what’s it called? A DFX CB. Ten D fx. You know what DSG stands for?

Speaker 2:                           07:35

No idea. Diamond flow.

Speaker 1:                           07:40

That doesn’t really. It’s diamond flow. I’m dfx. What’s the micron rating? 10. 10 microns. Now when you hold those together comparatively speaking, what we’re in comparison, what are some of the things that you recognize when to the other one’s a little bit more solid than the one in your left hand there. The diamond flow. Okay.

Speaker 2:                           08:03

Definitely more solid surface than this is solid, solid filter.

Speaker 1:                           08:11

It is a solid filter. So diamond flow. What is that? What is the. What are the selling points for diamond flow? It takes out the chlorine taste and odor, the bad taste and odor instead of, Oh yes, here’s what it looks like on the inside. Okay, so diamond flow is two filters in one. The reason that feels solid, like you said, because it has that outer exterior segment filter on the outside, it’s a melt blown exterior and it has a carbon block on the inside. So what you have is a particulate filter on the outside I depth filter, right? I’m catching stuff all the way through it and then I have a carbon block on the inside net. Carbon black looks like that and it’s rated for what size? Ten, 10 microns. So all of the. All of the flow paths in that way. What you’re looking at here is under an electron microscope, all the water’s going to flow through these little caves and crevices and as it makes its way through, it’s going to come in contact with all of the surface of our activated carbon. And how big are those openings on that diamond flow? Ten microns, 10 microns, right there at the surface. And it’d be nine microns because it could catch 10 microns.

Speaker 1:                           09:21

It’s Raven. Okay, sure. I’ll just. It’s actually nine point nine seven. No, you’re right. Okay. I just gonna catch 10 micron sized components on the outside. Nice. I liked that. That was getting pain. Again, keep yours open the. So the outer surface, right? Here’s the thing though, right on the outer surface of that block, if I’m looking at the outside of this right here, that’s what it looks like. So I’m starting to filter out 10 micron size items right here. I want to protect that. I don’t want it to get content. I don’t want to load that up right away. And then not use the rest of the filter. So now wrap it with this melt blown cartridge on the outside where I’m going to catch 10 micron. I’m going to have a 10 micron filter for a depth filter and catch a lot more of this stuff on the outside and protect my carbon block.

Speaker 1:                           10:17

So that’s what diamond flow is. It’s like a two in one instead of material. That’s polypropylene. So the way that’s made, Alex, is this. And we make, so that exterior is what’s called a melt blown cartridge, so you’ll have a core and it’s just a cylinder that’ll rotate. You have a nozzle that’ll shoot out melted polypropylene and it’ll just go up and down on the outside of that core shooting a thread of melted polypropylene on there until it builds up a filter. So it was like a three d printer. We’re three d printing a filter cartridge. Okay. And based on whatever the size of that nozzle is and how much pressure and everything determines how Stott, what size of openings we have in that filter. This one size for 10 microns. Okay. And it’ll just make that. We cut out the center of that and put a carbon block in the middle. We also made cartridges that are just this just for sediment loading. Does it pretty quick? Yes. So it doesn’t go on a cast, it’s just sit around something it dries, it’ll cure by the time it comes off of the tool that’ll be cured. And then we’ll cut it to length. What’s that one standard? It’s called a cold on a hot plate stamp.
