Drinking water treatment with ozone

Water treatment approaches for algal toxins in drinking water

BIRMINGHAM — In Water Technology’s “Professor POU/POE – October 2014” Technical Editor Dr. Joseph Cotruvo discusses algal toxins in drinking water as a result of algal blooms and various water treatment options available.

In the article, Cotruvo offers the following water treatment approaches including physical removal, chemical conversion and adsorption:

  • Conventional treatment that includes coagulation, flocculation, sedimentation and chlorine disinfection can remove most of the algal cells, but toxin removal is more problematic. It is essential to remove the algal cells by filtration prior to the addition of any oxidant such as chlorine. The oxidant will lyse the cells and release the toxins into the drinking water.
  • Oxidants/disinfectants such as chlorine, chloramine, chlorine dioxide, ozone, potassium permanganate and ultraviolet (UV) light are frequently available in a water treatment facility, or can be added, and provide a range of efficacies against the toxins. The following relate to Microcystin-LR, which is a common form of an algal toxin and among the most potent:
    • Ozone will rapidly lyse the cells; it is effective against the toxin at ozone doses of five ppm or less and at very low concentration-time values (CT in mg-min/l). CT means concentration in mg/l x time in minutes, so for example, a concentration of one mg/l for 10 minutes would be the same as 10 mg/l for one minute. Elimination of Microcystin-LR is virtually instantaneous.
    • Potassium permanganate will lyse the cells and is also a very effective, rapid treatment for the toxin. The CT value for complete elimination is about 25 mg-min/l.
    • Free chlorine will lyse the cells and it is very effective, achieving nearly complete elimination at CT of about 60 mg-min/l. Chlorine is present in almost every surface water treatment plant and probably functions both as an oxidizing and chlorinating agent.
    • Chlorine dioxide is a good disinfectant and lyses cyanobacteria cells, but it has no reactivity toward the toxin.
    • Monochloramine has some reactivity against the cells but not towards the toxin.
    • UV light irradiation at high doses has a destructive effect on the cells but does not affect toxin concentrations.
  • Membranes such as reverse osmosis (RO), nanofiltration, ultrafiltration and microfiltration are all effective for the removal of cells. Pretreatment and frequent cleaning could be necessary. RO and nanofiltration, but not microfiltration, would be effective for toxin removal.
  • Adsorptionusing powdered activated carbon is a short-term technique for the removal of geosmin, 2-methylisoborneol and toxins. However, the efficacy is variable and is affected by water quality factors. Granular activated carbon (GAC) is effective if the filter is of sufficient depth and condition but it is subject to exhaustion and exceeding capacity. Only a few GAC systems are in place in the U.S. that are regularly/frequently reactivated; most applications are in shallow fixed beds for routine taste and odor control and not reactivated for years, so their performance is not generally predictable in a sustained algal bloom. Biological activated carbon filters would be more likely to have sustained performance without frequent reactivation, because they usually incorporate ozone that would react with the toxins and provide the opportunity for microbial degradation of chemicals on the GAC surface.

Annapolis Cosmetic Dentist Introduces Oxygen Ozone Therapy to Enhance Dental Treatments

Dr. Yasaman Roland Now Uses Oxygen Ozone Therapy to Improve the Treatment of Oral Infections, Gum Disease, Cavities, Tooth Decay and More

ANNAPOLIS, MD–(Marketwired – Oct 16, 2014) – At the Center for Innovative Dentistry and Facial Aesthetics, Annapolis cosmetic dentist Yasaman Roland, DDS centers her practice around a holistic approach to dental care. Whether she is performing teeth whitening treatments or dental implant procedures, her focus is on helping each patient achieve a beautiful smile while also improving the overall health of their mouth and body.

Recently, Dr. Roland implemented a new state-of-the-art technique known as oxygen ozone therapy into her practice. Utilizing an all-natural oxidant called ozone (O3), she says this revolutionary treatment is intended to sterilize areas of the mouth and/or water-based dental instruments by eliminating disease-causing bacteria and other harmful microorganisms without the use of chemical solutions. This, she adds, can eliminate the possibility of toxic side effects sometimes associated with disinfecting chemicals that have been traditionally used in the field of dentistry.

As highlighted in How is Oxygen Ozone Therapy Used in Dentistry? — a recent blog post on Dr. Roland’s website — some common uses for oxygen ozone therapy can may include treatment of the following oral issues:

In regard to why she chose to implement oxygen ozone therapy into her practice, Dr. Roland says: “Oxygen ozone therapy can enhance virtually all outcomes of dentistry. For example, while treating gum disease, we can make an oxygen ozonated solution and apply it directly to the gum pockets and diseased area to eliminate infection — all of which can be done without usage of any pharmaceutical drugs and their potential toxic side effects.

“Another way oxygen ozone therapy can be applied is for the treatment of cavities, which are essentially tooth infections no matter how large or small they may be. The larger they are, however, the more potential they have to extend into the root system of the tooth and cause abscesses brought on by infection. With oxygen ozone, we can actually limit the decay upon exposure to the ozonated solution. If there is a moderate amount of cavity in the tooth, or even a cavity that is close to the nerve, we can apply oxygen ozone and potentially stop its progression. So not only have we suppressed the decay process, we have also created a much cleaner environment in which to work as we rebuild the tooth.”

Ultimately, Dr. Roland says by employing oxygen ozone therapy alone or in combination with another procedure, the innovative new technique can have a significantly positive impact on oral health, as well as the rest of the body.

About Yasaman Roland, DDS

Dr. Roland earned her dental degree from the University of Maryland Dental School and completed her postgraduate training at the world renowned Las Vegas Institute for Advanced Dental Studies. She offers an extensive range of cosmetic dentistry treatments and procedures at her Annapolis practice, and she has been named a “Top Dentist in America” by the Consumers Research Council of America.

Ozone use for mold remediation in homes and buildings

Mold Expert Offers Ozone Gas Decontamination of Ohio Homes & Buildings To Kill Germs & Mold


Certified Environmental Hygienist Phillip Fry recommends that Ohio houses and commercial buildings be germ and mold decontaminated at least annually with high output ozone gas.

Montrose, MI, September 25, 2014 — To kill disease-causing bacteria, viruses, and toxic mold growth that frequently infest over half of the homes and workplaces in Ohio, Certified Environmental Hygienist Phillip Fry recommends that buildings in the Buckeye State be treated at least annually with eight hours of high output ozone gas throughout the building, including inside heating/cooling air ducts, attic, basement, and crawl space.

High output ozone gas is an effective antimicrobial oxidizer that can be safely applied as a disinfectant, sanitizer, and decontaminating agent in both residences and commercial buildings, according to Mr. Fry, who is also a Professional Industrial Hygienist, co-manager of EnviroFry, and webmaster since 1999 of the mold information website www.moldinspector.com, plus www.ohiomoldinspection.com.

Ozone, which has been validated by scientists since 1906 for a multitude of pathogens in an array of applications, kills all known human pathogens, such as Ebola, H7N9 avian flu, SARS, and almost all other disease-causing viruses, bacteria, and fungal species such as the health-destroying Stachybotrys, Aspergillus, Penicillium, and Chaetomium toxic mold species.

Ozone is safe to use provided that are no workers or residents, pets, or live plants inside the building during the actual ozone treatment process, and for one to two hours afterwards.

Studies have proven that ozone is more efficient and has a higher oxidation kill potential than most traditional disinfectant/sanitizers (e.g. chlorine, hydrogen peroxide, peroxyacetic acid and chlorine dioxide), and its use eliminates the need to alternate different sanitizers because germs and viruses cannot build a tolerance to ozone. Ozone is non-corrosive to the surfaces of buildings and furnishings, and leaves no residue (treated surfaces never need a final fresh water rinse).

In depth information on the use of ozone for home and building decontamination is provided at www.ozonegeneratorkillsmold.com.

EnviroFry provides ozone home and building decontamination, plus mold inspection, mold testing, and mold remediation services in Akron, Canton, Cincinnati, Cleveland, Columbus, Dayton, Findlay, Lima, Mansfield, Marietta, Medina, Springfield, Toledo, Youngstown, Zanesville, and all other Ohio communities.

Elevated levels of indoor germs and mold have been linked to over 100 major health problems, including lung cancer, breathing problems, chronic coughing and sneezing, chronic sinusitis, chronic headaches and memory problems, chronic tiredness, skin rashes, and many other serious medical problems that are listed on the home page of the mold information website www.moldinspector.com.

Ozone used in dentistry

Irvine Dentist Embraces Biological Dentistry with Ozone Machine

Ozone giveth and ozone taketh away

Ozone protects us … but it’s deadly, nonetheless.

Ozone is crucial to life on Earth. At concentrations as modest as only eight parts per million, the ozone in the stratosphere blocks much of the sun’s harmful ultraviolet radiation.

Closer to the ground, however, it can be detected by some people in concentrations as low as 10 parts per billion – and it can be a serious problem, especially for the elderly, small children, and anyone with breathing difficulties caused by lung or heart problems or asthma.

All of that would only be an interesting bit of trivia, if it weren’t for the fact that hot weather – such as we are currently experiencing – coupled with normal to high levels of air pollution can cause a build-up of ground-level ozone.

And that, according to Metro Vancouver air quality monitors, is what has been happening, particularly in the eastern parts of the region, during the current hot spell.

The high concentrations of ground-level ozone are expected to persist for several days, probably until the current weather system moves along.

The Air Quality Advisory suggests avoiding strenuous outdoor activities during mid-afternoon, when ozone levels are highest. Exposure is particularly a concern for infants, the elderly, and those who have underlying medical conditions, as noted.

If you are experiencing symptoms such as chest discomfort, shortness of breath, coughing, or wheezing, follow the advice of your health care provider, and stay indoors in air-conditioned spaces.

While you’re at it, pay attention to the other dangers of unusually hot weather, like dehydration and the heat itself.

Drink plenty of liquids, especially water. Try to keep cool. If you don’t have an air conditioner at home, find a mall or public building to get away from the heat.

And be mindful of the dangers of kids and pets left in hot cars.

About SGX Sensortech (IS)


The article discusses salient features and applications of the MiCS-2610 ozone gas sensor.

Basically the instrument can be used for determining the levels of ozone from an ozone-generating source within a building as well as for identifying dangerous concentrations of ozone in the air outside.

To prevent water and dust contamination of the sensing element, the sensor is placed inside a housing. By gas diffusion, ozone-containing air reaches the sensing element. When electric resistance is changed in the sensing layer, a voltage change occurs. The voltage change is utilized to determine an equivalent concentration of ozone with the aid of a microcontroller. The voltage can also be used to raise an alarm when the sensor’s voltage is compared with a pre-set threshold voltage (Figure 1).

Figure 1. Schematic of a portable ozone detection system with built-in alarm

Operating Conditions

The MiCS-2610 ozone gas sensor satisfies the specifications mentioned in Table below:

Parameter Symbol Typ Min Max Unit
Life time tl 5 5 year
Switch on/off cycles ncycle 100’000 100’000
Heating power PH 70 mW
Relative humidity range RH 50 5 95 %RH
Ambient operating temperature Tamb 20 -40 70 °C

Measurement Circuit

The sensor unit is provided with 5V power (Figure. 2). An 88Ω resistor Rserial is connected in series with a heating resistor Rheaterl so as to achieve a nominal heating power of 70mW.

RSl is calculated using the following formula:

     RSl = RL /(VCC – VS) # x VS

Figure 2. Electronic circuit to power the heating resistor and to measure the sensing resistor

The changes occurring in the Rheaterl cause heating power variations, which are compensated by the simple circuit as shown in Figure 3.

For heating resistor values between 60 and 120Ω, the relative heating power variation is ±2 %.

Figure 3. Ph as a function of Rh. Rserial = 88 Ω and VCC = 5 V

Heating Resistor

The sensing layer’s temperature is based upon both the ambient temperature and the heating power. It is ideal to maintain the sensing layer’s temperature within 350-400°C in order to gain quick response times and good sensitivity. When it goes below 350°C, sensitivity reduces thereby causing the sensor response to be much slower. Likewise when it goes above 475°C, the structure of the sensor can be damaged due to excess heat.

The graph (Figure 4) shows ΔT as a function of Ph where ΔT is the temperature increase and Ph is the applied heating power.

While in operation mode, the heating resistor gradually increases (Figure 5). However when a constant heater voltage is used, heating power decreases. If the power compensation circuit is constructed as per figure 2, loss of power can be limited. Around 40% of Rh increases after the 10,000h of operation, thereby resulting in less than 2% of heating power.

Figure 4. ΔT as a function of Ph

Figure 5. Relative increase of Rh as a function of power-on time at ambient temperature

Gas Sensitivity

The graph (Figure 6) displays the sensitivity of the MiCS-2610 to CO, H2, ethanol (VOC), and CH4 (HC). Many interfering gases are known to be reducing gases that make the resistance to decrease; however ozone, which is an oxidizing gas, makes the sensing resistance to increase. The sensor’s resistance value varies with respect to humidity and temperature.

The gaseous form of water is humidity and reacts with the sensing layer similar to a reducing gas. When it is increased, there is a decrease in the sensing resistance. Similarly, temperature also behaves in the same manner as humidity. The negative temperature coefficient is because of the semiconductor properties found in the sensing layer material.

Ozone Kills Insects in Grain

Insects affecting cereals, maize, rice and other dry plant products can be controlled with ozone, writes Janne Hansen of AARHUS University.

To say that the harvest is in the house is not the same as saying that it is safe. An army of small, hungry bugs are ready to make a meal of the food source. Ozone (O3) in low concentrations can potentially replace insecticides to control insects in stored grain. Scientists from Aarhus University together with the company Crop-Protector KS have investigated the effectiveness of ozone in different doses on a range of insects and under different conditions. One of the research objectives of the project was also to develop a machine that uses ozone as a pesticide.

Some insects can do a lot of damage even in dry stored products. Scientists from Aarhus University studied the effectiveness of ozone against insects in their various stages. Photo: Lars Damberg

Grain weevils, lesser grain borers, flour beetles, , several species of moth and others of the same bent can do great damage to stored barley, wheat, rice, maize and other dried plant products if the insects are not controlled. The grain is often stored for many months and in that time the insects can in all secrecy multiply into a very large number. 

In the industrialized countries up to 9 percent of the stored grain may be lost. In developing countries, the loss may be 20 percent, and in some instances it may all be lost. The problem is discovered perhaps only in connection with a transaction when the grain has to be transported elsewhere. Pests are a major factor in pricing the grain. Besides the economic losses that result from an infestation, there may also be health problems when the grain is used for food. 

One way of controlling such infestations in grain is to spray the grain with insecticide, but there is generally a desire to cut back on this approach. Scientists from Aarhus University have been testing ozone to see if it can be used as an effective controlling agent against pests in grain. 

One of the problems with conventional insecticides is that they initially only act on the insects that live freely among the grain. In some species (grain weevils, for example) eggs, larvae and pupae develop concealed within inside the grain kernels, where they are well protected from any chemical sprays, explains associate professor Lise Stengård Hansen from Aarhus University. 

It is only when the insects have developed into adults and eaten their way out of the seed that they are exposed to and affected by the insecticide. Therefore, the insecticide needs to be effective for many weeks so that it is still active when they appear. There are not many effective agents available for this purpose, partly because the insects have become resistant to the active ingredients and partly because some agents are no longer allowed.

Ozone, instead of poison

Another option is to use ozone. Ozone is a gas which is highly oxidizing and is used for disinfection in other situations. Microorganisms are, for example, very sensitive to low concentrations of ozone. The advantage is that ozone is an unstable gas and quickly converts to the oxygen molecule (O2), which is harmless. The ozone is produced in situ by an electric high-voltage process and can be used in, for example, a grain silo. 

One of the aims of the research was to examine how effective ozone is at different development stages of the insects and find the best combination of dose and duration of treatment. The scientists looked at the effect of ozone on 11 different species of insects that cause damage in dry stored products. Past studies have only looked at the effect on insects that were freely exposed to ozone, but this project included the insect stages developing inside the grains. 

They looked at the effect of different temperatures and the physiological effect of ozone by examining the level of oxidative stress and the transcription of the genes involved in the insects’ natural defences against oxidative stress. 

The scientists found that in order to kill all the bugs that live freely among the kernels, they had to use 35 ppm ozone for six days. If the stages of the insects living inside the kernels had to be eradicated too, they had to use 135 ppm ozone for eight days. 

There are variations in the amount of ozone needed to control the distinct stages and types of pests: adult insects are generally more sensitive to ozone and often die after a treatment with 25 ppm for five days. There is also a variation in the sensitivity for the internal stages, but to eradicate all stages, the high dose of 135 ppm for eight days is used. 

The project is supported by The Danish AgriFish Agency under the Ministry of Food, Agriculture and Fisheries and by Crop-Protector KS and Aarhus University.
