  • New treatment uses ozone and oxygen in hand-held device to treat herniated discs

    Read full story HERE

    Herniated disc sufferers at Vancouver General Hospital are being treated with ozone/oxygen treatment to reduce the size of their herniation (lower back) and ultimately reduce their pain and suffering.

    The oxidating effect of the ozone/oxygen appears to shrink the disc and pulls the herniation away from the irritated nerve.

    “There was a strong suggestion that patients got better more rapidly with the treatment. What we’re hoping to see here is that through the ozone process, healing will occur rapidly and patients won’t need other interventions like repeated steroid (cortisone) injections and surgery,” said Dr. Peter Munk, the lead radiologist in the study.

    “The disc is like a fibrous doughnut and you get a herniation when an inner part of the disc bulges out through a weakened area,” Munk said, adding that the majority of herniations occur in the lower back, potentially leading to pain in the back and legs by pinching on spinal nerves.

    The studies main objective (now recruiting 25 participants) is to determine the safety of the injection delivery system. CT imaging is used to precisely guide the needle (similar to what is used in complicated epidurals.

    The whole process takes approximately 20 minutes and is an outpatient service.

    The procedure should reduce the cost to the health care system compared to more traditional treatments (surgery etc) and reduce the level of complications patients have to endure.

    Dr. Kieran Murphy (University Health Network) developed the treatment (AO-1000) which is owned by Active-O Inc.

    The treatment is available in other countries however the new device is handheld and utilizes a syringe delivery system.

    For the patient, it adds another layer of treatment before having to consider surgery which many people view as a last resort.

  • Comparison of oxygen concentrator styles

    Oxygen Concentrator Types Compared

    The purpose of this article is to explain the main types of oxygen generators available for ozone production and the advantages/disadvantages of each.

    There are a few manufacturers of oxygen generators and a few differences between each. However, the fundamental operation of each manufactures version is very similar so that will not be reviewed here. We will focus on the three main styles of oxygen generators and how they could be implemented into your ozone generation system.

     

    Sequal and OGSI OEM Oxygen Generator
    Industrial oxygen generator

    Generally smaller ozone systems will use the turnkey oxygen generators, and larger ozone systems with higher ozone production rates will use the industrial oxygen generators, while small to medium integrated ozone systems will use the OEM modules. However, there are applications where the industrial style oxygen generator is required for higher pressures, or turnkey oxygen generators are required due to the lack of space or available compressed air.

     

    Turnkey Oxygen concentrators

    Packaged oxygen generators that include an oil-less compressor, PSA oxygen generator, and all components to concentrate oxygen from ambient air. These units only need electrical power for operation and will provide oxygen at 93% purity.

     

    Examples:

      • OGSI, OG-15 and OG-20
      • AirSep, AS-12 and Onyx
      • Sequal (Chart), Workhorse line

    Turnkey packaged oxygen generators from airsep, OGSI, Sequal

     

     

    Advantages:

    • Compact size allows for install in relatively tight spaces
    • Turnkey design allows for quick and easy operation
    • Relatively low cost

    Disadvantages:

    • Lower oxygen output delivery pressures due to limitation of internal oil-less compressors
    • Poor reliability due to the lack of ability to purge moisture from process air
    • High maintenance costs due to poor reliability

     

     

    OEM Modules

    OEM models are offered by both OGSI and Sequal (Chart). The OEM modules use the same PSA sieve beds and valving systems as the turnkey packaged oxygen generators provided by those companies. These modules are commonly used to build ozone generators with integrated oxygen generators, or smaller integrated ozone systems.

     

    Examples:

      • OGSI, OG-15-OEM and OG-20-OEM
      • Sequal (Chart), ATF Modules, ATF-8, ATF-12, ATF-15, ATF-23, ATF-25, and ATF-32

    OEM oxygen generator from OGSI and Sequal

     

     

    Advantages:

    • Compact size allows for install in relatively tight spaces
    • OEM configuration allows for installation into the same enclosure as an ozone generator if desired
    • Use of compressed air from plant air compressor may allow for very clean, dry air to be used increasing reliability dramatically when compared to the turnkey packaged oxygen generators.
    • Can provide slightly higher oxygen delivery pressure than turnkey packaged oxygen generators due to the higher compressed air inlet pressures that can be used
    • Lowest potential operational costs if plant compressed air is used

    Disadvantages:

    • Installation equipment is required and must be done properly for reliable operation
    • Lower oxygen output delivery pressures than industrial oxygen generators
    • Potentially high replacement costs (applies to Sequal/Chart ATF-modules)

     

     

    Industrial Oxygen concentrators

    Industrial oxygen concentrators are used for medium to large scale ozone generation systems. These systems require compressed air for operation along with proper plumbing and set-up. Large steel cylinders are used to hold the molecular sieve material, and quality rebuildable solenoid valves are used to perform all purging and oxygen recovery actions.

     

    Examples:

      • OGSI, OG-25, OG-50, OG-100, etc
      • AirSep, AS-A, AS-B, AS-D, AS-E, etc

    Industrial oxygen generators from Airsetp and OGSI

     

     

    Advantages:

    • Long term reliability of the system – only periodic maintenance is required
    • Lower overall long-term operational costs than other options due to low cost for rebuilding the unit
    • Higher oxygen delivery pressures (45 – 65 PSI)
    • Higher oxygen flow-rates available

    Disadvantages:

    • Higher up-front capital costs for oxygen generator, tanks, and potentially the air compressor
    • May require more physical space for installation
    • Greater installation work required

  • Ozone Exposure Chamber Demonstration

    We have a great video (see below) of our CH-1 ozone chamber in action.  This video shows the operation of the CH-1 ozone chamber, but also is a great demonstration of the oxidizing power of ozone and how different materials react to ozone.

     

    A latex glove is on the right while a silicone glove is on the left.  On the bottom, there is a glove stretched over a roll.  On the top, the glove is simply hanging from a wire.  It is clear the latex glove is oxidized much faster.  However, it is important to note that silicone is also not completely ozone resistant.

  • Ozone Safe, Effective for Knee Osteoarthritis Pain

    Read Full Article HERE

    Intra-articular ozone may provide pain relief, functional improvement, and gains in quality of life (QoL) in patients with knee osteoarthritis (OA), according to a study recently published in PLoS One.1

    The intervention, which was conducted by a team of Brazilian researchers affiliated with the Sao Paulo Federal University in Brazil, was shown to be safe and effective. “Although many clinical series reports have been accomplished, no randomized, double-blind, placebo-controlled clinical trial had been accomplished until now,” said lead investigator Carlos César Lopes de Jesus, MD, in an interview with Clinical Pain Advisor.

    ozone relieves knee pain After 8 weeks of treatment, statistically significant differences favoring ozone were seen in several efficacy measures.

    A total of 98 patients with symptomatic knee OA were enrolled in the trial and randomly assigned to receive intra-articular injections of ozone (20 μg/mL; n=63), or air (10 mL; n=35) once weekly for 8 weeks. Efficacy measures included the Visual Analogue Scale (VAS); Lequesne Index, in which patients with knee OA rate pain and function on a 0 to 24-point scale; Timed Up and Go Test, which evaluates balance and fall risk; SF-36 Health Survey Instrument, which evaluates QoL on a scale of 0 to 100 (0 =worst health); Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC); and the Geriatric Pain Measure (GPM).

    After 8 weeks of treatment, statistically significant differences favoring ozone were seen in several efficacy measures. A significant reduction in pain as measured by VAS, GPM, and WOMAC scores was seen in the ozone group compared with the placebo group (P <.001). Differences in WOMAC scores, particularly toward the end of the treatment course, also indicated a significant improvement in joint stiffness and engagement in physical activities (P <.001). Lequesne Index measures also indicated a significant reduction in pain and improvement in function (P < .001), and QoL in relation to function, pain, and general physical and mental health was also statistically superior in the ozone group compared with the placebo group (P <.001). No significant differences were observed between groups in relation to the Timed Up and Go Test.

    The study investigators reminded clinicians that symptomatic knee OA affects more than 9.3 million US adults and is a leading cause of disability. Agents to slow progression are lacking. Ozone therapy has been used as an alternative therapy in some chronic conditions such as rheumatic and osteoarthritic disease.

    “In my opinion, ozone injections are more effective than the use of corticosteroids and nonsteroidal anti-inflammatory agents [NSAIDs] for the treatment of knee OA,” said Dr Lopes de Jesus. He explained that ozone has a significantly broader mechanism of action than NSAIDs and corticosteroids, providing anti-inflammatory and antioxidant effects and the ability to deter antalgic gait.2 “Ozone activates the cellular metabolism, reduces prostaglandin synthesis, makes the redox system function properly by reducing oxidative stress through induction of the synthesis of antioxidant enzymes, and ameliorates tissue oxygen supply through hemorheologic action, vasodilatation, and angiogenic stimulation.“ Dr Lopes de Jesus added that ozone has been reported to have a restorative effect once it mobilizes bone marrow, mesenchymal, and endothelial stem cells, but no study had demonstrated this until now.

    Puncture accidents, which occurred in 2 patients in the placebo group and 1 in the ozone group, were the only reported adverse events in this study. Adverse events are rare and comprise acute and transitory pain in the knee at the moment of ozone application, said Dr Lopes de Jesus.

    The investigators concluded that their results are encouraging and warrant further study.

    Summary and Clinical Applicability

    The value of intra-articular ozone for pain relief and functional improvement in patients with knee osteoarthritis was confirmed in a randomized double-blind placebo-controlled clinical trial.

    Limitations and Disclosures

    According to Dr Lopes de Jesus, the main limitation of the current study was the lack of imaging examination control to evaluate the impact of treatment.

  • Updated Calibration Chamber

    Recently Oxidation Tech updated our calibration chamber and process.  We have been using a smaller chamber or individual processes to calibrate each sensor we receive one by one.  With our new calibration chamber, we can calibrate as many as 10-15 ozone monitors at one time.

    Calibrate ozone monitors Ozone Calibration Chamber

    This calibration chamber still uses our Thermo Fischer Transfer Standard Ozone Analyzer to measure and control ozone levels inside the chamber.  However, with the use of an external ozone generator and automated control system a precise ozone level can be maintained inside the chamber at all times.  This saves time and potentially provides a higher quality, more accurate calibration for your device.

    Ozone exposure chamber Complete O3 Calibration Chamber/O3 Exposure Chamber

    Our ozone calibration chamber can also be used to high range calibrations up to 1,000 ppm, or can be used for ozone exposure testing.  As this sealed chamber has great capacity and automation any device a customer may need to be exposed to ozone can be placed in the chamber to be exposed to known and tightly controlled ozone levels.

    We also offer ozone exposure testing for higher range ozone levels, and lower range ozone levels in a smaller chamber.  Ozone exposure chambers are also a part of our standard product line as these are a popular requirement for many material testing facilities.

    Should you have any questions on ozone calibrations, please contact our office.  We would be glad to help with any ozone monitor calibration.

     

  • Measure ozone production rates real-time

    Tracking performance of an ozone system real-time is valuable for pilot test and even full-scale ozone systems and may be easier than you think.

    Ozone system output is measured in g/hr or lb/day.  These values indicate the production rate of an ozone system.  Knowing the production rate of your ozone system real-time can have value in tracking system performance and preventing system failures by spotting potential issues before they start.

    To calculate ozone production both the oxygen flow-rate and ozone concentration must be measured.  Both of these values can be measured real-time with digital devices installed inline with your ozone system.

    ozone pilot system example install with measuring devices Ozone generation system example with a Mass Flow Meter, UV Ozone Analyzer, and Oxygen Purity Meter installed inline.

    Mass Flow Meter:

    Mass Flom Meter GFM GFM Mass Flow Meter

    The GFM Mass Flow Meter will measure and display oxygen flow through your system real-time with a pressure compensated flow rate.  A mass flow meter measures the overall mass of gas passing through the device using ultrasonic technology.  This ensures reliable and repeatable flow measurements that do not require any conversions for temperature or pressure changes to the gas stream.  An LCD display or digital output can be provided to record oxygen flow rate.

    UV Ozone Analyzer:

    UV-HCR High Concentration Ozone Analyzer UV-HCR Ozone Analzyer

    The UV-HCR Ozone Analyzer will measure ozone concentration real-time to indicate the actual concentration of ozone produced by your ozone generator.   The UV Analyzer uses UV absorption technology to measure ozone concentration.  This unit provides an LCD display or digital output to record ozone concentration.

    A sidestream of ozone gas must flow through the UV ozone analyzer (1-2 LPM).  Some of the ozone will be destroyed in the UV lamp measurement tube, the remaining must be converted back to oxygen safely using an ozone destruct device.

    Oxygen Purity Meter:

    OXM-12L Oxygen Purity Meter OXL-12L Oxygen Purity Meter

    The OXM-12L Oxygen Purity meter will measure oxygen purity real-time to ensure the oxygen purity remains stable and sufficient for efficient ozone production.  Ultrasonic technology is used to measure the composition of gas and ensure oxygen purity remains consistent.  This unit provides indicator lights to display oxygen purity and a digital output, an LCD display is optional.

    Data Logger:

    DL-3 Ecosensors data logger DL-3 Data Logger

    Data from each of the devices can be input into a PLC for real-time calculation and reporting of ozone production in g/hr or lb/day.  Data can also be recorded with a simple datalogger that can record data from each device real-time to be recorded for later review.

    When measuring ozone concentration in % by weight the feed-gas (air or oxygen) must be factored into the calculation as oxygen and air have different weights. When calculating a percentage of a weight, it is necessary to know the weight of carrier gas.

     

    Ozone Calculations:

    Ozone Calculations and online calculators can be found at the links below:

     

    Ozone generator output

    ((LPM x 60) x 0.001) x g/m3 = g/hr

    Example = ((10 LPM x 60) x 0.001) x 10 g/m3 = 6 g/hr ozone production

     

    Ozone Concentration in air by weight

    100 g/m3 = 7.8% O3

    1% = 12.8 g/m3 O3

    1% = 7,284 ppm O3

    Ozone Concentration in oxygen by volume

    100 g/m3 = 6.99% O3

    1% = 14.3 g/m3 O3

    1% = 6,520 ppm O3


  • Ozone removes color from water

    Ozone does a great job removing color from water.  Ozone is an oxidant and will bleach water efficiently.  We were recently shipped a sample of wastewater from a client looking to have us determine if ozone would remove color from their water.  We were very impressed with the results, and decided to share, see video below for impressive results of ozone removing color in this water sample:

    The water sample shown is 250 ml. Ozone is generated from oxygen. Oxygen/ozone flow rate of 1 LPM is initiated about 5 seconds into the video. Ozone concentration is 10% by weight.

    For more information on ozone use for color removal in wastewater, see our website at the link below:

  • Ozone Bubble Diffusers - stainless steel

    We have recently obtained some new Stainless Steel Ozone Bubble Diffusers.  These are excellent options for your simple ozone system using a bubble diffuser.  These diffusers are constructed of sintered stainless steel and offer a 20 micron rating bubble size.  Max flow rates are 2.7 CFM and 5 CFM.

    Ozone diffusers Ozone Bubble Diffusers

    We offer these diffusers in 2 sizes.  Each has a 6" long diffuser attached to a pipe nipple with a 1/4" Male NPT threaded connection.  The difference in sizes we offer are only diameter differences.  This allows more surface area of the diffuser itself, and therefore a higher maximum flow capacity.

    Quantity discounts are offered for each diffuser, see our website for details on discounts.

    Ozone Diffuser Features:

    • Sintered stainless steel construction is strong and reliable for many years of service
    • Threaded connection offers a solid seal to your piping or tubing
    • Hex nipple allows a wrench to be used to tighten or later remove the diffuser from your fitting or piping, this eliminates the potential of breaking the diffuser when twisting the sintered steel
    • Welded construction
    • 20 micron rating allows for very small ozone bubbles
    • 6" length is sufficient to offer great surface area, but without the extra length to minimize damage

    Tips for using a bubble diffuser:

    • Before attempting to dissolve ozone into water ensure you understand the principles of ozone solubility well.  Click HERE for more information
    • Water tank must be vented to safely remove excess ozone/oxygen from the tank
    • Diffuser should be placed at the bottom of the tank
    • Taller tanks and taller water heights will increase mass transfer of ozone into water as the water pressure is higher at the bottom of the tank, and the gas bubble must travel farther in the water.
    • Ozone generated from oxygen will dissolve into water more efficiently than ozone generated from air
    • Ozone generated at high concentrations will dissolve into water most efficiently, target the highest concentration ozone possible when using a bubble diffuser.
    • Colder water temperatures will achieve highest dissolved ozone levels.
    • Use counter-current water flows across the bubble diffuser

    ozone bubble diffuser Drawing of example of ozone bubble diffuser in use

    Above drawing gives a great example of how an ozone bubble diffuser can be used in a very simple system.  A great advantage to this system vs those that use a venturi injector is that there is no water pump required in this system, this is a very passive, and energy efficient system.  Many of the failure prone pieces of equipment of a traditional ozone injection system are not used in this system.  Consider this in your next ozone system.

    ozone bench-test system Ozone bench-test system using bubble diffuser

    A great opportunity to use an ozone diffuser is a simple bench-test system.  Set-up a column to dissolve ozone into constructed of glass or PVC.  We use PVC pipe and place a diffuser in the bottom of the pipe via a tee.  This allows the column to be 5-feet tall or more.  This allows a great opportunity to maximize ozone transfer into water.

    The drawing above shows a complete system, if you are interested in setting a system like this up, let us know.  We sell and rent all this equipment, or can provide this testing for you in our facility.

     

  • Oxygen Purity Meter

    Oxygen purity is important for ozone production.  The better the oxygen purity going into your ozone generator the more ozone can be produced.  Therefore, being able to know the purity of the oxygen going into your ozone generator is important.  We recently released two oxygen purity meters that are able to measure 0-100.0% oxygen.  These units are designed to be placed in line after your Oxygen Generator and before Ozone Generator to measure the purity of oxygen coming from the Oxygen Generator and into your Ozone Generator.  The inlet and outlet connections are 1/2” Female NPT Fittings. Both models are equipped with a relay alarm for low oxygen purity as well as a 0-10 VDC and 4-20mA output signal.

    O2 Purity Meter – Low Flow

    This unit is capable of measuring 0-100% oxygen in flows at 6- PSI and inline flows up to 12 SCFH (6 LPM).  There are 3 color indicators lights that indicate the current oxygen levels:
    Green = above 85%
    Yellow = 75% – 85%
    Red = Below 75%

    An optional upgrade on the O2 Purity Meter Low Flow model would be an LCD display to show current oxygen levels.

    O2 Purity Meter – High Flow

    This unit is capable of measuring 0-100% oxygen in flows at 100 PSI and inline flows up to 127 SCFH (60 LPM).  This unit is comes with an LED integrated display that shows the current oxygen readout in a resolution of 0.1%.

    Oxygen Purity Meter High Flow with display

    Optional Add-ons

    Both units have a few custom options that depending on your application might be beneficial.  The optional add-ons are:

    Wireless Monitoring & Data Logging Kit

    This can be mounted next to your oxygen purity meter and connects to the internet which allows you to access the data from anywhere.  You can receive notification via text and e-mail alerts.

    Wireless Monitoring & Data Logging Kit

    Visual Strobe Light

    A strobe would be installed on the unit as a visual indicator when oxygen purity is registering below 75%.

    Audible Alarm

    An alarm can be installed on the unit to sound when the oxygen purity is reading below 75%.

    If you have questions on your current ozone system set up and how these oxygen purity meters would work in your set up, please contact us.

  • Ozone Therapy for TB treatment

    Ozone Therapy in India successfully treats patients with TB.  Great news story out about the use of ozone for the treatment of patients with TB.

     

    Bhavesh Thakkar has been holed up in the depressing surgery ward of Asia’s largest tuberculosis hospital in Sewri for over a year. Thakkar, 39, developed Empyema, collection of pus in the pleural cavity. The condition requires drainage of pus from the chest every day.

    ozone therapy for TB treatment Critical patients suffering from TB treated with ozone

     

    “The drainage bag would fill with a litre of pus every day. I had no strength to stand, and had lost hope,” Thakkar said. Ozone therapy, however, has turned around his deteriorating condition.

    “Recently, doctors brought in a machine, and started me on a saline wash for the lungs through an incision on my chest.” After 20 sessions, the leaking pus has stopped, and efforts are on to make Thakkar infection-free. He is on anti-TB medication and may need surgical intervention for damaged lungs.

    Bisleri International Pvt Ltd donated the ozone therapy contraption to the Sewri TB Hospital two years ago. It lay gathering dust until a month ago when a group of surgeons felt that it could be useful for critical TB patients.

    The machine emits ultra-violet light sparks which split oxygen into free molecules and generate two per cent ozone and 98 per cent oxygen. “Basically, oxygenated ozone is sent through a tube mixed with saline. A saline wash is administered to infected wounds,” said Dr Lalit Anande, Chief Medical Officer, Sewri TB Hospital.

    “Ozone has worked on patients on their death bed. It works as painkiller and an anti-inflammatory, has immunity-boosting anti-oxidants, and kills germs. About 40 patients have benefited from the therapy so far,” said Dr Anande.

    Ozone therapy can also be administered through drinking water route for all TB patients and hospital staffers to boost their immunity, Dr Anande said.

    The therapy was used during World War I to disinfect wounds, but somehow it has not seeped into the Indian fabric of treatment, says Dr Kuntal Pal, a leading pulmonologist from Mumbai. “We will need to study the patients who are being administered the therapy at the Sewri TB Hospital to understand how well it works,” he said.
