The city of Montreal is using ozone for waste water disinfection. This great article was put together to explain the use of ozone ozone. This is great PR as many times the use of ozone is misunderstood by the public. By educating the public there is buy-in for all parties. This is important as we all pay tax dollars for these systems.
Ozone consists of three oxygen atoms joined together into a single molecule of ozone. It is produced by the discharge of electricity in air. Ozone generators send an electric current through air or oxygen, which splits the molecules into separate oxygen atoms that combine with others to form ozone.
It is then injected into water in special tanks, where it breaks down bacteria by destroying cell walls. It also destroys 75 per cent of viruses, as well as the majority of pharmacological and cosmetic-based pathogens, considered important because Montreal is host to many of those industries.
Once the water has reached the end of the contact tanks, which in Montreal’s case are pipelines running 30 metres underground for kilometres before they spill into the St. Lawrence, disinfection is complete, and the ozone has converted back to oxygen.
Widely used in Europe, ozonation is much less popular in the United States because capital costs are high compared with other technologies like UV or chlorine, although disinfection rates are much higher. Maintenance expenditures, mainly for electricity, are also comparatively high, but this is less of a concern in Quebec because of it’s low cost hydro-electricity.
Montreal’s ozonation plant is expected to cost $9 million a year to run. Currently, Montreal’s waste water filtration plant spends $12 million a year to cover electricity costs.
Is ozonation the right solution to clean Montreal’s waste water?
In three years, Montreal plans to start operating the largest ozonation waste-water filtration system in the world. If all works as planned, the $285-million plant will inject ozone gas into the water to destroy the vast majority of bacteria, viruses and the more recent addition of pharmacological-based toxins before they’re flushed into the St. Lawrence River.
“This technological advance will soon elevate Montreal to be among the world leaders in waste-water purification,” Montreal Mayor Denis Coderre said in late March as the city announced the launch of the $100-million first phase of the project. An environmental boon to the health of downstream residents, be they plant, animal or human.
Except that being the first raises some troubling questions, especially when more than a quarter of a billion taxpayers’ dollars are at stake.
Being first is “foolhardy” in the opinion of McGill environmental engineering professor Ronald Gehr, who has specialized in waste-water treatment for over 25 years.
“Why are these technologies not more widely used? Because they don’t work,” Gehr said. “They are not efficient for waster water. They are efficient for drinking water.”
Waste-water plants in the United States abandoned ozonation because results were disappointing, Gehr said. Other municipalities typically use it as a secondary treatment process, after waste water has already been partly disinfected. Using it as a primary treatment method in Montreal, which has what is believed the third-largest waste treatment centre in the world, is unprecedented and risky, Gehr argued.
The fact only two companies bothered to bid on the $100-million portion of the contract that involves building the ozonation plant shows Montreal is going in a direction most companies find too risky, Gehr said. Degrémont Limité was ultimately chosen because it was the only bid that conformed to specifications. Gehr has been raising warning flags about the city’s intentions since public consultations were held in 2008.
“I felt at the time it was foolhardy to jump in and create the largest ozonation plant in the world for treating waste water whereas we just don’t have the expertise — we should rather build a smaller one somewhere and test it out like a pilot plant.” More consideration of ultraviolet radiation technology is warranted, and Gehr questioned whether the need justifies the expense.
Estimates for the total cost are already 40 per cent higher than the $200-million price tag given in 2005. Gehr predicts final cost overruns will be “huge.”
At Montreal’s Jean-R.-Marcotte waste-water plant on the eastern end of the island, everything is built on a scale designed for the gods. Four immense concrete wells plummet 17-storeys underground to collect water from the sewage receptor pipes running along the north and south sides of the island. Seventeen motors in the sub-basement, boasting 4,800 horsepower apiece, can each pump a backyard pool’s worth of water skyward in half a second.
The plant handles a volume of water that would fill Montreal’s Olympic Stadium every day. It handles 45 per cent of all the waste water produced in Quebec. When it was constructed nearly 30 years ago, it was the biggest in the world.
“When we built this plant, they said we were crazy,” Richard Fontaine, the man responsible for treating Montreal’s waste water, said during a tour of the bowels of a plant that is spotless and odourless despite its vocation. “Now they’re building them even bigger. If we can work this, I’m not worried about the new ozonation plant. I’m used to big stuff.”
Montreal’s plant collects the water that spews from toilets and storm drains, industrial plants and snow collection dumps, then filters out the solids, sands, and gravel, and treats it with chemicals to take out 70 per cent of the phosphorous, which promotes algae growth that clogs rivers and lakes. Leftover sludge is collected as a form of earthy mud that Fontaine delights in handing to gloved guests. (“I’ve had ministers hold this stuff, ” he chuckles “Even prime ministers.” ) The mud is incinerated.
While this is a step up from dumping untreated sewage into the river, it still does little to remove the bacteria borne mainly of human excrement dumped liberally into the St. Lawrence, as well as viruses and pharmacological pathogens emanating from medications dumped by patients, industries and users of illicit drugs.
“I don’t think the fish were expecting anti-depressants,” Fontaine said. Nor anti-inflammatories, hormones and anti-convulsant medication to temper the affects of Parkinson’s and epilepsy. Ozonation will remove 95 per cent of bacteria, most viruses and 75 per cent of pharmacological and cosmetic items, research studies show.
The province has been spared major environmental and health repercussions because of the huge amount of water flowing down the St. Lawrence that dilutes the effluent dumped into it, noted Viviane Yargeau, associate professor of chemical engineering at McGill University and specialist in waste-water treatment technologies. To this day, swimming is not recommended for several kilometres downstream of Montreal. Once the ozonation plant is installed, “indirect contact” with the water, meaning, for instance, water-skiers wearing wetsuits, will be possible within 300 metres of the city’s outflow pipes, and swimming allowed a kilometre downstream, Fontaine said.
A team of engineers, microbiologists, chemists and other experts mandated by the municipal and provincial governments have been researching the best solutions for over a decade, and decided on ozone in 2008. UV treatment for Montreal would be less efficient, almost equally costly and require the use of tens of thousands of glass tubes, which would have to be cleaned regularly, a prospect Fontaine said kept him awake many a night. Montreal’s plant has been testing ozonation for years, on a scale equivalent to that used by smaller municipalities, with excellent results. The only difference will be to increase the concentration of ozone used.
Fontaine said the capital costs of installing ozonation, most of which will be covered by provincial and federal grants, is not exorbitant when compared with the overall worth of Montreal’s plant, which Fontaine estimates at $3 billion, and the volume of water it treats. Cities like Toronto have at least seven waste-water treatment plants, whereas Montreal has just one to equip. There were only two bidders on the ozonation plant because there are few firms worldwide with the expertise to work at this level, Fontaine maintains. Initial cost estimates were low because there was nothing to compare with worldwide, and the city lowballed their estimate to keep bidders from charging too much. Final estimates will hold up, Fontaine promises.
“I don’t really see why the size is a concern,” Yargeau said. “It’s not just been tested, but implemented in many places in Europe, and even many cities in the United States. If it’s sufficient at a smaller scale, why shouldn’t it be effective on a large scale? … It’s great news.”
Montreal’s plant will be able to meet tightening environmental standards for decades to come and adapt to the new chemical toxins, Fontaine said.
While Fontaine said years of testing have gone into the decision, Gehr still feels the city is acting too hastily.
“The die has been cast, and you and I will be paying for it over the next I-don’t-know-how-many years,” he said. “I agree that ozone is more effective. But is it worth it?”
Fontaine said he’s convinced it is.
“We fight pollution, that is our mission,” Fontaine said. “I believe in that. If you’re asking me is it worth it, this kind of investment, my answer is for sure. This project is the best environmental news — this is not a line, this is what I think — probably the best environmental news touching our waste-water treatment and our waterways in 30 years. … It’s a good idea for my kids and your kids and their kids.”
Ozone use is finding more and more small scale applications. Traditionally ozone has been used in large water treatment plants for drinking water and wastewater treatment. As the technology improves and becomes more mainstream new applications for ozone continue to grab hold.
EnviroPure has developed a great application for ozone to conserve water in food waste disposal systems. In fact the National Restaurant Association (NRA) have given an award to Enviropure for this system.
EnviroPure receives NRA innovation award, expected to save restaurants 400 gallons of water a day
April 22, 2015
Commercial foodservice and plumbing product manufacturer T&S Brass and Bronze Works announced the National Restaurant Association awarded the company the Kitchen Innovations Award for its new EnviroPure ozone recirculation option. The product is designed to eliminate the need to add fresh water during the organic food waste disposal system’s digestive process. The ozone recirculation option relies on naturally-extracted water from food waste as it processes through the system, breaking down food waste within 24 hours, the company said in the announcement.
Through a combination of mechanical processing and aerobic decomposition, an all-natural, micronutrient additive accelerates the digestive process, turning the food waste into a safe grey water byproduct that meets municipal wastewater requirements. The grey water is infused with ozone, which acts as a cleansing agent, the release said. The purified water then recirculates in a bubbler tank until further needed. Excess water can be used for irrigation or other non-potable purposes.
“A typical foodservice operation could expect to save about 400 gallons of water a day using this ozone infusion option,” said Jim Slanina, president of EnviroPure. “At a time when we’re beginning to realize water is not an unlimited resource, we think this will be a welcome innovation.”
Denver, CO has released it’s annual water quality report.
The 2014 Water Quality Report for Danvers is available: Click here.
The report covers all testing performed between January 1 and December 31, 2014.
Upgrades To The Water Treatment Process
“Upgrades have been added to the treatment process including ozone. In contact with raw water, ozone neutralizes waterborne cysts and oxidizes most of the organics (taste, color, and odor). Ozone is also used in contact with water following the settling step to enhance the filtration process and further reduce organics. In addition, a 50% filtration capacity has been added to the facility. This will provide the necessary treatment capacity to meet both water demand and regulatory compliance for years to come. And finally, in the name of fiscal economization, new pumps, new electrical systems, and a new residuals de-watering system have been installed.”

Hydrogen Peroxide (H2O2) is a difficult gas to smell and identify without a sensor. However H2O2 can be a toxic gas. Read the great article below on this topic to learn more about H2O2 odor thresholds and H2O2 safety.
Hydrogen peroxide vapor has no smell, and is imperceptible at concentrations below a few hundred ppm. Therefore odor is an unreliable indicator of the presence of hydrogen peroxide and in applications where hydrogen peroxide vapor is present a continuous monitor should be used for occupational safety..
When thinking about whether continuous monitors are needed for hydrogen peroxide sterilizers, hydrogen peroxide aseptic lines and other uses of hydrogen peroxide, the question arises as to what is the concentration that people will be able to perceive the hydrogen peroxide vapor and whether they can perceive the hydrogen peroxide vapor below the concentration it becomes hazardous.
So far I have been unable to find a reference that gives an odor threshold for hydrogen peroxide. Some references say that hydrogen peroxide has no odor, others that it has a slightly sharp odor, or sharp odor and bitter taste. Jon Ruth in his review  of odor thresholds did not give an odor threshold, but said the odor was slightly sharp and became irritating at 150 mg/m3 (108 ppm).
Solvay, one of the larger manufacturers of hydrogen peroxide says “hydrogen peroxide has very little odor at the lower concentrations found in consumer products” and most people seem to agree that at low concentration there is no odor, at 3%, 6% and even up to 30%, though others report a slightly acid odor at this concentration. Personally I smelt nothing from bottles of either 3% or 30% solution.
Solvay went on to say that “hydrogen peroxide has a slightly sharp, pungent odor in higher strength industrial concentrations” and others report that pure hydrogen peroxide has a smell similar to nitric acid, though FMC (now peroxychem) say that 90% H2O2 is odorless, as did Thenard, the discover of hydrogen peroxide in 1832. Therefore, in summary hydrogen peroxide has little or no odor at concentrations below about 30%, but at very high concentrations some people perceive a sharp smell, but others do not.
Schumb et al wrote that “It is difficult to characterize the smell of hydrogen peroxide. In fact, it is probably to be questioned whether it affects the olfactory cells or merely stimulates the general nerves of the nasal membrane. Concentrated hydrogen peroxide manifests little odor unless occasion is deliberately taken to inhale near the surface of the liquid in a container or unless it has been spilled extensively. The sensation perceived is then reminiscent of ozone or of the halogens. … If circumstances arise to cause the dispersion of considerable hydrogen peroxide in the air, as a mist, there ensues after a short time considerable irritation. Prolonged breathing in such atmosphere induces gasping such as is encountered with ammonia or sulfur dioxide. This is accompanied by a sharp, burning sensation in the nasal passages on inhalation and exhalation.” The much greater acute effect of hydrogen peroxide mists compared to gas probably corresponds to the much higher amount of hydrogen peroxide delivered.
The equilibrium concentration of hydrogen peroxide vapor over 30 % H2O2 solution is about 470 ppm, based on its vapor pressure at 25 oC. which is well above the OSHA PEL and the various STELs discussed above. Personally I found there was no smell from 20 ppm hydrogen peroxide vapor, and I have no desire to test higher concentrations.
The ATSDR (part of the U.S. Department of Health and Human Services) stated “Because it [hydrogen peroxide] is nearly odorless and nonirritating except at high concentrations, persons may not be aware of its presence. No odor threshold was located for hydrogen peroxide (the OSHA PEL is 1 ppm). Detection of odor does not provide adequate warning of hazardous concentrations.”
Therefore if one is using hydrogen peroxide where there is a risk of exposure to the vapor, odor is not a reliable method to detect if the hydrogen peroxide concentration becomes too high and so a continuous monitor for hydrogen peroxide is needed.
In some applications such as when using sterilizers there is an odor that people sometimes associate with hydrogen peroxide. As far as I know no studies have been performed to identify the origin of this odor, and it is probably the result of partially oxidized volatile organic compounds, perhaps derived from the oxidation of minor components of sterile wraps or other polymeric materials. Similarly, odors can persist after ozone treatment of rooms for much longer than ozone will be present, probably also due to the formation of partially oxidized VOCs. Whatever the source of the smell, people who work near hydrogen peroxide sterilizers who have a hydrogen peroxide monitor present can be glad that it is not hydrogen peroxide vapor. Those who do not have continuous monitor for hydrogen peroxide may also be glad the smell is not hydrogen peroxide but they will still wonder how much hydrogen peroxide vapor they are breathing in.

Ozone use for purification is common in many applications. We found a story about a company right here in Iowa using ozone to produce Vodka. While this may not be a common ozone application it is certainly interesting. Read the article below, or click HERE for full story.
A professor’s quest for the purest vodka
Liquor was always more than a drink for Ames resident J. Hans van Leeuwen.
It was a science experiment, and, to him, the distillation process longed for further perfection.
As a boy, Leeuwen, a Dutch native raised in South Africa, was fascinated by his parents’ advocaat, a drink that involves infusing eggs with vodka.
As a young educator, his brother’s pot still and its endless moonshine possibilities intrigued the scientist, newly trained in the ways of methodical trial and error.
And as a seasoned Iowa State University engineering professor, Leeuwen’s research into air and water purification triggered an epiphany: He could use his lifetime of experiences and reams of knowledge to create a volatile-impurity-free vodka.
After more than a decade of work, Leeuwen’s vision of a cleaner, smoother liquor has been realized — and bottled — as ingeniOz vodka.
Made with corn sourced from Iowa, drinking ingeniOz or any clear alcohol with fewer impurities might result in a lighter hangover. Federal regulations bar ingeniOz’s makers from saying as much, but a 2009 Brown University study found people who drank alcohol with more impurities or “congeners” reported feeling worse than people who drank liquor with less impurities.
On a recent hot spring day, Leeuwen, 68, met with investor Jerry Krause and distiller Todd Dunkel, owner of Cumming’s Iowa Distilling Company, which produces ingeniOz along with a suite of other spirits.
Standing near the big, blue ozone generator and various filtration systems responsible for ingeniOz’s purity, the men peppered funny family updates with discussions on sales plans and production strategies. The brand, which launched last summer, has been “just barely” in the black since December, according to Krause.
Leeuwen, the Walter White behind ingeniOz, is the Vlasta Klima Balloun Professor of Engineering at Iowa State. In addition to a collection of scientific honors, Leeuwen was named 2009 Innovator of the Year by R&D magazine, an award also given to Larry Page (Google) and Elon Musk (Tesla). And he has patents like most people have punches on their Subway Sub Club cards.
Leeuwen’s vodka experiment is a passion project for the scientist, one born of his personal enthusiasm for distilling.
“I’ve always been interested in the various flavors of alcohol,” Leeuwen said. “I’m curious about different drinks. I always want to try them.”
The liquor analysis is an offshoot of Leeuwen’s main research topics, including producing animal feed from ethanol industry waste and the treatment of ships’ ballast, the water held in a ship’s hull to keep it afloat.
“I work a lot in water and air purification and a natural part of that process is ozonation (the use of ozone gas to aid purification),” Leeuwen said. “You could actually take fairly polluted water and with an ozonation process, make purified water. That brought me to the idea of using this type of approach with alcohol. That was really the big ‘aha moment.'”
The purity of ingeniOz vodka and Leeuwen’s findings that ozone gas can facilitate the removal of volatile impurities from alcohol were independently verified by both Iowa Distilling Company and two of his ISU colleagues, Lingshuang Cai and Jacek Koziel.

Vodka is supposed to be devoid of “distinctive character, aroma, taste or color,” according to the Alcohol and Tobacco Tax and Trade Bureau. Unlike spirits such as whiskey or gin that employ impurities for flavor or color, vodka doesn’t need additives, aging or the right zip code to be classified as vodka.
The difference — in price and taste — between various vodka brands is in how well impurities are filtered out of the base ethyl alcohol. “Bad” vodkas don’t do a good job of filtering impurities, hence their metallic, robot-corpse flavor and battery acid burn.
“Good” vodkas filter out impurities so that the liquid is, well, basically flavorless.
IngeniOz goes a step further than filtering by first exposing its liquor to ozone gas.
To make a complicated process simple: Iowa Distilling Company pushes ozone gas through 190-proof ethyl alcohol and, in doing so, alters the impurities in the alcohol and makes them easier to absorb, according to Leeuwen. Then, when the alcohol is filtered through activated carbon, impurities that were previously nonremovable are eliminated.
Many vodkas, even good vodkas, fall victim to the “filter myth”: the idea that just continuing to filter liquid over and over will make it purer.
“In general, whether you use three filters or 1,000 filters, whatever got through the first one is going to get through the next one, too,” Dunkel said. “We are changing the product (through ozonation) in such a way where we are able to get volatile impurities out that filters can’t. It’s a different approach. It has never been used before and it works.”
Pouring a taste for himself, Leeuwen pauses before sipping to address the morality of his process. Is a purer form of vodka that’s easier to drink really a good thing?
“If people aren’t going to drink our product, they are going to drink something else,” Leeuwen said. “If they are over 21, it’s legal. I don’t feel guilty because if people drink responsibly, like we do ourselves, they will be pretty safe.”
Then, staring at the ingeniOz bottle and its bright blue label, Leeuwen sighs deeply before asking his partners if they like the bottle. And what about the logo design? The tagline?
The men fall into a deep discussion, analyzing each element.
They have a very long way to go to compete with worldwide brands like Absolut and Smirnoff, but for Leeuwen and his partners, the “ozone’s” the limit.
