How MIOX’s Electrolysis Process Works


Video Transcription:
The MIOX electrolysis process of on-site chemistry generation begins when salt and water are combined to form a brine solution. Alternatively, an industrial brine byproduct or seawater can be used as feedstock.

The brine solution is fed into a MIOX electrolytic cell. Our proprietary electrolysis process converts the dilute brine into a disinfectant by passing an electrical current through the solution inside the electrolytic cell, converting chloride ions into chlorine-based disinfection chemistries.

MIOX on-site chemistry generation processes are safe, cost-effective, and deliver superior disinfectants to industries around the world.

Tech Brief: Electrochemical Generated Disinfectants by Dr. Andrew Boal

MIOX electrochemical generators, or On-Site Generator (OSG), combine salt, water and power to generate your water disinfection on site and on demand.

The electrolytic cell, where the oxidants are produced, is central to the OSG process. Electrolytic cells consist of two electrodes, the anode and cathode. The cells are arranged so both electrodes make contact with the water and brine solution mixture. When the OSG is activated, an electrical current flows through the cell, causing chemical reactions on the surfaces of both electrodes that eventually produce the disinfectant.

MIOX electrolytic cells are developed with a proprietary geometrical design, electrolytic scheme, and solution flow characteristics. This proprietary knowledge is what allows MIOX to lead the hypochlorite market in terms of efficacy, stability, ease of use, safety and, in most cases, cost.

MIOX works in partnership with your site and current water treatment professional. We offer flexible procurement options ranging from capital sale, lease and rentals.

MIOX’s Mixed Oxidant Solution: How it Works

MIOX’s Mixed Oxidant Solution is different from other forms of chlorine and biocides.

We put together a technical briefing that showcases the chemical and microbiological analyses differences between MIOX’s Mixed Oxidant Solution (MOS) to other biocides and forms of aqueous chlorine.

As a leader in on-site generation (OSG) innovation, MIOX learned early on that the electrolytic cell inputs and operational parameters could be tuned to produce aqueous chlorine solutions with substantially different oxidation and disinfection properties.

These observations, coupled with extensive engineering and microbiological research, allowed MIOX to develop a unique OSG product line capable of producing highly reliable MOS.

Case Study: How a Cooling Plant Dramatically Increased Safety and Reduced Costs

How did this centralized cooling plant transform their underperforming cooling towers and turn them into the biggest safety improvement in the facility’s history?

The funny thing about this installation was that after rolling out a 30-week testing phase with MIOX to monitor performance, we discovered they were using a lot more biocide than originally thought. That meant that the size of the on-site chemical generators they were using in this test phase were actually smaller than what they actually needed.

But this is where things got interesting.

Even though the generators were too small, MIOX performed just as well as their old solution, but did it at a fraction of the cost, and while drastically improving the entire plant’s safety.

They used to receive deliveries of five 650-gallon chemical totes and chlorine dioxide. With MIOX, they were replaced with one delivery of table salt. With MIOX’s patented Mixed Oxidant Solution, all you need is: salt, water, and electricity to generate the chemicals on-site.

A Safe Alternative to Chlorine Gas

Video Transcription:
Are you aware that a well-known chemical weapon has been the go-to solution for disinfection… in our own backyard?

For years, Chlorine gas has been used as a disinfectant for many industries. The reason? Its low perceived cost. But in reality, its multiple risk factors give it a much higher actual cost when factoring in insurance and safety-related expenses. At MIOX, we have a better solution: on site chemical generation.

MIOX on site generation is safer than Chlorine gas because the primary ingredient is nothing more than table salt. And the solution is less than 1% concentration. It’s easier thanks to an automated process that produces oxidant only when needed. And because it’s inherently safe, it’s less costly than Chlorine gas over the long-term. With a unique chemistry that outperforms other disinfectants, MIOX is the best, most reliable disinfection solution in the industry. And it’s the safer, more responsible choice.

How MIOX Works in Cooling Towers

Video Transcription:
If you’re thinking that you can’t save money while improving water quality in your cooling tower, then think again. Reality is: you have biological growth in your cooling system. Even if it’s not apparent or easy to see. To make matters worse, you’re paying too much for your bulk hypochlorite or your biocide.

Imagine cutting that cost by more than half and improving your results at the same time. Now you can with MIOX. MIOX is cheaper because your chemical is generated on-site. We don’t have trucking. Your disinfectant is made fresh each day. The only operating costs are salt and electricity. It’s more effective so you don’t need as much, and it doesn’t degrade like bleach.

MIOX is generated using environmentally-friendly ingredients: salt, water, and electricity. It’s so safe that it offers no health or safety hazards to your site or your people whatsoever. A <1% concentration means no PPE, no reporting, and an HMIS rating of:

1 for health
0 for flammability
0 physical hazard

In other words, it’s safer than hand sanitizer. Here’s how it works in your tower: MIOX replaces all biocides used in your water systems. MIOX offers a combination of bleach and peroxide which is as effective as chlorine dioxide. The peroxide creates fissures in the biofilm, allowing the hypochlorite to kill underneath the slime layer. This reduces chemical dosing and lowers the ORP, in turn, lowering the corrosivity of water and allowing inhibitors to be more effective. And for alkaline programs where bromine is used, MIOX is effective at elevated pHs.

A recent industrial client used MIOX and increased their production capacity by 7%, producing millions in additional savings. MIOX can offer you a solution that’s cheaper, safer, and more effective — making your job easier, and making you look like a hero.


MIOX Hypochlorite Generator: The Manufacturer Makes a Difference

Video Transcription:
So now you’re looking for an on-site hypochlorite generator, but have you considered the differences between manufacturers?

With MIOX, you’ll get:

  • A more efficient and reliable electrolytic cell with a unique design to ensure consistent production across the cell’s surface
  • Patented self-cleaning through reversing polarity of the cells, virtually eliminating the need for acid cleaning
  • Automated flow control that adjusts for unexpected changes in water pressure, reducing operator intervention
  • A single enclosure that dramatically reduces footprint and installation cost, and allows for comprehensive factory testing of the completed system before shipment, plus a modular cell design to easily increase future production capacity within the same enclosure
  • A safer hydrogen venting process via a liquid barrier with no moving parts, electrical requirements, or check valves
  • A fully automated control system with remote control capabilities and monitoring of operational parameters, allowing the system to proactively self-diagnose
  • A unique transformer-less design, which significantly reduces footprint, cost, and weight
  • The option to choose Mixed Oxidant Solution (MOS) for better biofilm removal and better efficacy
  • Not to mention an elegant design that resists rust and looks brand new for years to come

Most on-site generation systems don’t have it all, but after continuously investing in technology with more than 50 patents, MIOX does, which makes it the most technologically advanced on-site chemical generation product out there.

How MIOX Eliminates Legionella

MIOX controls Legionella.

Our Mixed Oxidant Solution is more effective at removing biofilm and Legionella from water compared to common biocides.

And this isn’t our biased opinion.

We conducted a study comparing disinfection using three oxidizing biocides and three commonly used non-oxidizing biocides against Legionella pneumophila. The organism L. pneumophila is pathogenic and commonly lives within biofilms.

Which means that eradicating the biofilm in cooling towers is the first step towards preventing an outbreak.

There have been two published studies comparing the disinfection effectiveness of MOS with hypochlorite at various pH values. MOS consistently performs better at higher pH against a variety of organisms, including viruses, oocysts, and bacteria. Studies conducted at the University of New Mexico comparing equivalent chlorine concentrations of hypochlorite to MOS showed that, after 10 minutes of exposure at a pH of 8.0, MOS achieved total kill against L.pneumophila and P. aeruginosa while chlorine alone did not.

Case Study: How This City’s Water Distribution Serves 250 Square Miles

“I don’t think there’s anything better than MIOX.”

Video Transcription:
Fred Black – Field Manager for Entranosa Water in New Mexico.

Here at Entranosa, we’re spread out for about 250 square miles. About 18 or 19 years ago, we used to use sodium hypochlorite, so it was very heavy and back-breaking. It wasn’t too safe for the workers.

Sodium hypochlorite also, if you don’t use it fast enough, will lose its potency. And so that was another problem was disposing what we didn’t use. We also had problems with biofilm in the pipes. And we also had problems with the injectors really clogging up on a regular basis.

So we’ve been operating here with MIOX now since 1995. The automation is simple, I mean it’s just simple to use. MIOX is a lot cleaner, the biofilm is not there like what I used to see when I first started. It used to be a lot of brown stuff growing inside the pipe. We don’t have that anymore. What’s nice about MIOX is we’re finding out that the effects of the disinfection lasts a lot longer.

We have about 250 square miles that we have to distribute to. We can inject here at the site at the beginning about a .5 or .6 residual cure. By the time you drive 10-14 miles out further, we’re receiving .36, and sometimes .5. I don’t think we have any interference with the biofilm to eat up any of that.

It’s very safe. We’re only dealing with salt. We’re putting salt into these cans, and that’s all we’re dealing with. We don’t have to worry about having a hazard, or a break in the chlorine tank that we have to contain. HAA5s and trihalomethanes are two of the samples which are byproducts of chlorine that we have to control and test for. We have not had a hit since we’ve been using MIOX.

A lot of people that you’ll find out here in the New Mexico area, they buy bottled water to drink. A lot of the folks when they come out to the East Mountain area of Albuquerque, they specifically want to live on Entranosa’s system because they like the water a lot better. It must say something about the taste, and that’s a big plus.

I don’t think there’s anything better than MIOX.
