Reduction potential

Correct.

So what we're big in, in teaching people with, with the urine and saliva work that we do, one of the things that we test for in the urine is the urine ORP And one thing that we have found that almost all cancer people have, have a, a very high, uh, plus ORP, you know, and, and oxidation, uh-

Sure

... a high, a high oxidation scene.

So that, that, that kind of ties in.

You know, I'm not really a big chemistry guy, so it's like, you know, uh, I, I've observed this, but I didn't exactly know why, but now you're shedding some light onto why, why we see this.

And then of course our, our job is to teach people how to, you know, what they've gotta change, what they gotta change in their lifestyle to make that ORP drop because, you know, it needs to be below -20 is what w- what we have, uh, you know, uh, you know.

Yeah, yeah.

How can operators tell when an RO system is starting to drift out of spec before it becomes a real problem? And what should they be keeping an eye on day to day?

Well, the standard recommendation now, an RO unit is normally equipped with with pressure gauges, flow meters, conductivity meters, maybe a chlorine analyzer or ORP analyzer, various instruments to track performance.

Typically what a reputable RO manufacturer will supply or water treatment chemical firms also.

And I actually have an Excel program in this regard.

He was, he was just about one month, I think, from leaving to, to take on a venture at Texas State Aquarium in Corpus Christi.

A- and so I came in to a role that had been created specifically to, to, um, denitrify The Living Seas, but I quickly transitioned into the ozone world to try to understand ozone and ORP and the reactions that occur, uh, when ozone gets dissolved in our seawater.

Uh, and th- these were the days where they were dealing with air diffusers, air stones, things like that to deliver ozone to the water with large low surface area bubbles and hoping you got some ozone dissolved into the water, and this was really before the, the injectors, uh, were coming onto the scene.

And this is really interesting.

It's gonna kill fish." This is why it was the batch process first-

Right

... where we could control the chemistry, dose in the methanol at the right, uh, amount to match the balanced chemical reaction, don't overdose, make sure your ORP goes to about negative 200 millivolts, you're actively denitrifying a- and you don't overdose.

And so you've got a controlled environment batch, if you will, where you can keep an eye on all that.

Before, we used to

use ORP sensors to figure out what the chlorine, not necessarily levels, is because ORP is oxidation reduction potential, and that is a qualitative measurement of your chlorine.

Well, now they make a sensor, a PPM sensor, a parts per million sensor, which is a quantitative measurement of chlorine, and that's what the lifeguards use.

So that's what Juan's talking about, when we can go in there and see what they're actually seeing, not just a qualitative measurement, but we can also see the quantitative measurement now.

And it does so in this really elegant way.

So when you think about oxidizing agent, there's something called an ORP scale, oxidation reduction potential.

There are some substances that are really deeply, strongly oxidizing, and there are some that are weak.

Chlorine dioxide is actually weak and it's good.

So it was just getting ready to be tested.

It had an ORP system built into it, which is really ORP.

Yeah.

So at that point, now we're going to try to sell it.

something you pour dichlor into.

And the reason for it was dichlor is pH neutral.

It could dose based on ORP, a swimming pool, residential, commercial, or commercial hot tub.

Good concept, but the problem with dichlor, which you probably know, it's got cyanuric acid in it.

It's something that I don't believe anybody else has ever done.

So there's always been a bit of an inconsistency when testing for ORP in the industry.

And there's many things that go against getting an accurate result there.

But with the OptiCell, the way that it works is the water runs through and there's a testing reagent right here.

goes up into here, shines a light through the sample of water that's been mixed with the reagent, which will give you a free chlorine reading, an accurate free chlorine reading.

Almost, you know, 100% every time, not affected by pH levels in the water, not affected by the flow of water that's going through it.

The most accurate way to get a free chlorine reading, so it's not ORP, it's free chlorine, and then the chlorinator can adjust the chlorine output accordingly.

And the reagent as well in this small bottle here, Sharon, that would last roughly...

This was a floating smart monitor device.

It's a great concept, but it just did ORP and pH, and you would scan in a test strip, and it would give you the other information.

So it wasn't like this device did, you know, free chlorine, total chlorine, pH, alkalinity, cyanuric acid, and then gave you dosing recommendations.

It basically was...

Just a smart water monitor for ORP and for the pH and for the temperature.

And then every week or so you would scan in a test strip.

The problem with the Finn is, there was a couple problems with the Finn.

I thought it was a pretty good device for what you paid for.

So let's go back to our hidden chemistry.

Our hidden chemistry of iron basically says that when we take a sample from a well, we need to understand the ORP and the pH and that over time that ORP is going to change and the water is going to become oxidized because it's being in contact with air.

So we have iron two plus in A, then slowly it transforms into iron three plus and then it slowly transforms into iron hydroxide.

Now, when I talk to other people, I often mislabel the iron as rust.
