  • 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.

    “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.

     

     

  • Ozone Pilot Test Trailer

    We just started a new pilot test using our ozone pilot test trailer.  In this application, ozone is in use to remove 1,4-Dioxane and other VOC's from groundwater using in-situ remediation.

    ozone trailer Ozone pilot trailer on-site

    This site was contaminated from a legacy chemical plant that has long since been removed.  Site clean-up had been attempted with various other technologies over the years with success on other contaminates, but hard to break down VOC's remain at this site.  Ozone was chosen as a technology for the final phase of remediation on the path to final site closure.

    Our ozone pilot trailer has the ability to produce 80 g/hr of ozone from oxygen and push ozone to groundwater wells at pressures up to 50 PSI.  The trailer can be controlled and operated remotely via a telemetry system that allows full remote control and visual indication of system operation.

    Should you have a need for a portable and automated ozone system please let us know.   This pilot test is currently located on the east coast and is in operation in New York State.  The features of this system are outlined below:

    • 80 g/hr ozone generator
    • 40 SCFH oxygen production
    • Ozone manifold with 4 individually controlled outputs
    • Mass flow meter to indicate Oxygen flow real-time
    • Ozone analyzer to measure ozone concentration real-time
    • Ambient ozone leak sensor
    • Full telemetry system
    • Boost compressor to provide up to 50 PSI ozone delivery pressure
    • Oxygen pressure sensor
    • Ozone pressure sensor

    Trailer only requires electrical power for operation.  Either 120 VAC or 220 VAC power can be used for the operation to ensure flexibility for your application.

  • Ozone Generator Quality

    We get many questions about the quality and price point of various ozone generators.  These are fair questions as there are many price points for an ozone generator with the same basic g/hr or mg/hr ratings.  Here we will try to lay out the biggest differences in ozone generators.

    For a complete ozone generator buyers guide click HERE

    The purposes of this article we will be looking only at corona discharge ozone generators producing ozone from dry air or oxygen.  We will not be evaluating UV ozone generators or ambient air ozone generators used for air treatment as these both have very limited application.

    Corona Cell Materials

    The heart of any ozone generator is the corona cell.  This is where the corona discharge occurs and produces the ozone.  Materials such as aluminum, tin (tin foil), low-grade stainless steel and plastics can be used to lower cost.  This is typically the case for Chinese made ozone generators.  These materials will be attached by the oxidation of ozone over time, and create leaks or a failed corona cell.

    As these low-quality materials degrade they will contaminate the oxygen/ozone stream and allow impurities into the ozone stream.  Keep this in mind for water treatment or medical ozone applications.

    higher quality ozone generators will use high-grade stainless steel (316L), quartz glass, ceramic, and pure Teflon.  These ozone resistant materials will withstand ozone and create a longer life to the ozone generator.

    In 6-months of operation or very light use, there is no difference in corona cell materials.  Long term, after 6-months, or heavy use reliability of the ozone generator will be greatly affected. Costs will be higher to manufacture corona cells from higher quality materials.  However, the benefits are worth the cost.

    Transformer

    To produce ozone a high voltage spark is required.  This spark is occurring at all times and is an end-point ground.  A high voltage transformer is used to create these high voltages and sparks.  This transformer must be reliable and capable of handling the torment of shorting through a dielectric to ground at a high frequency for hours at a time.  We have found the best success with open coil resonant transformers, or oil cooled transformers.  Simple end-point transformers are less expensive and are commonly used in lower cost ozone generators, however, these will fail sooner.

    Electronic Driver Boards

    To produce ozone a high-frequency spark is used.  Electronic components must be used to create this high frequency.  Most commonly basic Mosfet transistors are used to switch DC voltage to create the high frequency.  Lower cost ozone generators will use one transistor to create the high frequency.  HIgher-end ozone generators will implement a series of transistors to split the workload.  

    Circuit protection

    In the event, the corona cell is contaminated, or adverse conditions exist the ozone generator driver board should turn OFF ozone production so that the transformer does not short directly to ground and fail.  Many lower cost ozone generators do not implement this circuit protection.  Those that do, may not react quick enough to protect the electronic equipment.  

    Cooling fans

    Ozone generators create heat.  That is a non-negotiable fact.  Many low-end ozone generators use small cooling fans that do not move sufficient air, and some use no cooling fan at all. 

    Ozone Concentration

    Ozone generators are normally rated with mg/hr or g/hr.  How efficiently this ozone is produced is a measurement of the ozone concentration, normally measured in % by weight, g/m3 or gamma.  It is important that the ozone generator you purchase produces the most g/hr at the highest possible ozone concentration.  Higher concentration ozone will consume less oxygen, dissolve into water more efficiently, and simply work better for every possible application.

     

    These are a few of the most important components to review on an ozone generator.  Of course, low-quality ozone generators serve a purpose, they meet a low price point, and allow a user to determine if ozone is right for them.  However, do not be confused, a $100 ozone generator is not a lifetime investment.  And as with everything, higher quality is going to cost more.

  • Ozone oxidation of MTBE and ETBE evaluated

    Ozone is commonly used to remove MTBE from groundwater and drinking water when MTBE is found in high levels.  Ozone is a viable option as ozone oxidizes MTBE rapidly from water, and completely after by-products are also oxidized.   Below paper gives great details on this process.

    Abstract

    The aim of this work was to study the reaction of ozone and combined ozone/hydrogen peroxide on oxygenated additives such as methyl tert-butyl ether (MTBE) and ethyl tert-butyl ether (ETBE) in dilute aqueous solution using controlled experimental conditions. Experiments conducted in a semi-continuous reactor with MTBE and ETBE in combination (initial concentration: 2 mmol/L of each) showed that ETBE was better eliminated than MTBE with both ozone and combined O3/H2O2. Batch experiments led to the determination of the ratio of the kinetic constants for the reaction of OH°-radical with MTBE and ETBE [kOH°/ETBE/kOH°/MTBE = 1.7). Tert-butyl formate and tert-butyl acetate were identified as the ozonation byproducts of MTBE and ETBE, respectively, while tert-butyl alcohol was found to be produced during the ozonation of both compounds.

    MTBE Removal Success

    Ozone has proven to be successful at oxidizing MTBE in water.  Ozone rapidly oxidizes MTBE, however, TBA (tert-Butyl alcohol) is formed as a by-product of this oxidation.  TBA is then oxidized by ozone, but at a slower rate than MTBE.  See chart directly below for a great example:

    MTBE removal from water with ozone create TBA

    Image from: Chemical Oxidation of MTBE and TBA

    The chart above shows a great example of MTBE removal in water with only MTBE and TBA data shown.  As MTBE was oxidized, TBA was created at the same rate.  After MTBE oxidation was nearly complete TBA oxidation started to occur, but at a slower rate.  TBA will also be completely oxidized from water with ozone over time.  Ozone remains a great option for oxidation due to the rapid oxidation of MTBE and complete destruction of both MTBE and TBA with no harmful by-products left in the water.

  • Ozone Remediation System Install

    We just finished retrofitting a shed and installing an ozone remediation system in Wyoming.  An Ozone Cabinet was used in a small shed to clean up gasoline contaminates in the water table.

    Ozone remediation cabinet Ozone remediation cabinet is installed inside this protective shed

    This was a great install and very clean when finished.  Small vent fans are used in this shed to remove excess heat.  Ozone delivery lines were stubbed up directly inside this shed in the concrete pad making this a very secure install.  A custom 2 lb/day ozone cabinet is used to provide ozone to up to 20 well outputs in this situation.

    Ozone is a great solution to removing MTBE, TBA, BTEX, and other common gasoline contaminates from groundwater.  Ozone can be used in-situ (as in this example) with minimal site disturbance and a very small footprint.

  • Aeroqual Ozone Detectors

     

    aeroqual ozone monitor Aeroqual Ozone Detectors can detect many environmental air quality gasses beyond ozone

    Aeroqual ozone detectors are the perfect solution when high accuracy, low-level detection of ozone is required.  Aeroqual provides ozone monitors in handheld or fixed mount versions that measure ozone as low as 1 ppb with reliable and consistent accuracy.  The Aeroqual ozone detector is the only sensor based technology that can accurately measure ozone at low levels, every other technology uses the much more expensive UV based photometer technology.  Aeroqual allows for small footprint and economical cost.

    Aeroqual ozone detectors can also be used to measure a wide variety of other gasses.  Sensor heads can be purchased and placed on the Aeroqual Ozone Monitor to measure those gasses with only a short warm-up period between gas detection.  Accessories, such as a carry case, remote mount kit, and wall bracket are also available to further add to the function of the Aeroqual Ozone Detector.

  • Improve your livestock drinking water supply

    As livestock producers in the USA grow in size, so do the water demands.  It is not always possible, and certainly not cost effective to bring municipal or rural water supplies to the farm, therefore drilling wells to supply water for on-site livestock is the best, and many times only option.  However, if your water supply is less than ideal, this causes potential issues.

    We can help.  Ozone is used by many municipalities around the USA to treat drinking water.  As the technology improves we can now bring this same quality of water to your livestock operation cost effectively.  

    Drinking Water Disinfection

    Ozone and H2O2 can be used to disinfect drinking water on your farm.  Both well water and rural water can benefit from water disinfection.  By reducing bacteria in water cows will be healthier and water will taste better.  Drinkers will grow less bacteria, algae, and require less cleaning.  Livestock will drink more water when treated with ozone or H2O2.

    How it works

    Well Water

    Well water commonly requires treatment to remove minerals or pathogens, even perfect well water may have no bacteria in it when pumped from the ground.  However, without any added disinfection this water can grow bacteria in it as soon as it is flowing through your pipeline and in your tanks.  This bacteria can spread illness, and make for generally unhealthy water in the drinkers.  Bacteria can easily be oxidized by ozone or H2O2, just as it is normally oxidized by chlorine in municipal water supplies.  However, using ozone or H2O2, dissolved oxygen levels in the water will increase and create healthier water without the added chloride contamination.

    Common well water uses for ozone

    Benefit of Ozone

    Ozone can improve water quality to your livestock.  Animals will drink more water if it tastes better and looks better, cows that drink more water will eat more food, therefore, gain weight faster,  and are healthier animals overall.

    Reducing bacteria in water will improve herd health and reduce maintenance on drinkers throughout your farm.

    Using ozone as opposed to chlorine or H2O2 will save costs as there is no chemicals to purchase.  Ozone equipment is a one-time purchase with only minimal maintenance costs.

     

    Ozone is dissolved into water using an ozone injection system.  The size of ozone system will be based upon your total water flow rate used.  Total water flow may be based on other applications for ozone on your farm or ranch.  See diagram of ozone injection system below for information on how ozone is dissolved into water.

  • Ozone therapy banned in Malaysia

    Ozone therapy has finally been gaining some mainstream traffic worldwide in the last few years.  In fact, at recent IOA conferences, and in the Ozone Journal medical applications of ozone has finally been given, time, space and honest evaluation.

    However, the country of Malaysia has recently banned ozone in medical applications by blanketly banning "ozone therapy".

    See link below for full new stories on this topic:

    This ban is getting reconsidered due to requests in the country:

    BALIK PULAU: The Health Ministry will do an indepth study on “ozone therapy” after the Ozone Medical Practitioners Association Malaysia asked that the ban on the treatment be reconsidered.

    Deputy Health Minister Datuk Seri Dr Hilmi Yahaya said the ministry would take another look although the treatment has been found to be dangerous and offers no benefit to patients.

    “Ozone therapy is a dangerous treatment as it has a molecule that is unstable and can produce air bubbles in the blood,” he told reporters after attending the Jom Cari Siput contest here yesterday.
