Non-indigenous aquatic species are a threat to marine resources around the world, with new introductions occurring on every coast. The introduction of NIS into coastal marine and estuarine waters comes from a variety of sources. Due to the large volumes and frequency of possible inoculations, ballast water is currently the most frequently cited method for the worldwide transfer of NIS. Annually, 21 billion gallons of ballast water are discharged into the U.S. .
Ballast water has been shown to contain a number of bacterial pathogens that can impact human health. Ballast water treatment by ozonation is one of the many treatment technologies being studied for implementation on board commercial vessels. Ozone will remove algae also and will eliminate deposit corrosion caused by biofilms. Please contact Ozone Solution for using ozone to disinfect ballast water.
Ozone not only has several applications in the industry sector, but it has interesting applications in the world of dentistry as well. Ozone dental therapy is an alternative therapy to conventional drilling and filling for non cavitated deciduous carious lesion. The infusion of Ozone into non-carious dentin prevented biofilm formation in vitro from S.mutans and Lactobacillus acidophilus over a 4 week period. Some studies have demonstrated that 40 second application of Ozone is sufficient to kill different concentrations of S.mutans and application of 60 second has almost completely eliminated S.mutans, L.casei and A.naeslundii. Ozone is also found to be effective against the microflora associated with primary root caries lesions .
Ozone can be used to help treat periodontal disease by using ozonated water flushed below the gum line and/or ozone gas infiltrated into the gum tissue and supporting tissues. Ozone can be employed in all forms during root canal treatment to kill bacteria, sterilize the canal system, and to stimulate faster healing. As a gas, ozone can get to places traditional liquids can’t because the gas can permeate the tiny tubules that cannot otherwise be accessed.
Ozone can be used to kill decay-causing bacteria. Since ozone is a gas, it can permeate into areas below the gum line, into the grooves of teeth and over the smooth surfaces of the teeth, and will kill bacteria on contact. Because ozone can harden compromised tooth structure, flooding a sensitive area or tooth with ozone gas can effectively eliminate sensitivity.

In a fish farm and aquarium, conventional solids removal, such as sponge floss filters and sand filters, are removing coarse and filterable solids, but they are not capable of removing fine colloidal solids. In another point of view, nitrifying bacteria in bio-filters remove dissolved ammonia and nitrite, but not all dissolved organic wastes. As an aquarium matures, the accumulation of dissolved organic colloidal solids increases. This organic buildup decreases the performance of the nitrifying bacteria which causes harmful nitrite buildup. The biochemical oxygen demand also rises, so the oxygen levels decrease over time. These shifts in water parameters stress the aquarium inhabitants and may cause fish mortality. To reduce the necessity of large water changes, there is a very efficient alternative method of breaking down these organic wastes using a strong oxidizing agent. This method is “Ozonation.” Ozonation has several benefits in fish tanks including:
- Removal of dissolved solids (TDS and TSS) by clumping them together to bigger dimension particles that can be removed by the protein skimmer or activated carbon.
- Ozone oxidizes Organic compounds in water (TOC) and breaks them to simple organics that are now available for degradation by heterotrophic bacteria.
- Reduction of harmful ammonia (NH3-) and nitrite (NO2-) levels by oxidizing them to nitrate (NO3-).
- Precipitation of metals, such as Iron and Manganese.
- Algae and biofilm removal
- Removing smell by destroying sulfides.
- Degradation of pesticides, detergents, and possible trace of acetone, MTBE which will keep water healthy for inhabitants.
- Ozone kills 99% of bacteria and viruses and dramatically reduces BOD and COD levels.
- Increased water clarity (even if it had been very clear before ozone)
Ozone, at the end, reverts back to oxygen and increase dissolve oxygen level in water. The right ozone level is very important to keep fish healthy and the overdosing of ozone will be harmful for inhabitants.
The AC-500 is a versatile machine as it can operate with either a vacuum or a positive PSI (motive force) of up to 5 PSI. That versatility makes the AC-500 series a good choice for small research & lab applications. If you do not have a force to move the feed-gas through the machine, there is a model which comes with a built in air pump which could solve that issue. Please see the chart below!
The machinery requires minimal setup and provides you a simple but effective solution to many small ozone required projects. This ozone generator will provide years of reliable ozone generation at a low cost, but if needed, the machine uses field replaceable components, and is completely serviceable.
If you need a suitable air drier, we offer you the MAG-600; http://www.ozonesolutions.com/products/Air-Dryers/MAG-600_Air_Dryer

As the number of individuals who are diagnosed with cancer increases, other forms of treating cancer have become more popular in the past decades. In today’s world there are many medical advances that have become available. For instance, those unfortunate enough to be diagnosed with cancer now have alternative options for treatment available then just chemotherapy. Since the early 70’s, ozone therapy has become another means to fighting certain cancers. Ozone is a chemically active form of oxygen. In terms of the medical ozone- it is a mixture of pure ozone and pure oxygen. “There is no exact ratio of these two reactants; it varies according to the medical ailment and patient’s condition.” .
The ozone is used in a couple of different ways. Of which includes “taking a pint of blood that is drawn from the patient. This is then gently mixed in an infusion bottle with the ozone until it turns bright red”. This method is called ozone major auto-hemotherapy, according to the Ozone-Association. This is when small quantities of ozone are “combined reacting completely then returned using a normal drip unit.” . Once entered into the system, a patient’s antioxidant system is boosted which aid in ridding the body of free radicals, it even goes as far as increasing the power of the immune system, allowing the body to produce more white blood cells. The ozone rich blood also “helps the body fight multiple infections and inhibit tumor growth.” . The molecular ozone is an effective disinfectant and an oxidizing agent which can aid in breaking down nearby cells like cancer cells. Another treatment for cancer is ozone intravenous. This process delivers a fluid straight into the bloodstream that contains ozone which is also used to increase the amount of oxygen in the blood .
There are some concerns of using ozone as a medical treatment since the Food and Drug Administration has labeled ozone as a toxic gas. When ozone is breathed in, it is considered hazardous on the tissue lining in the lungs and incites a slew of pathological effects. If a patient is given too much ozone it stresses and damages the cells, which is can enable the progression of certain degenerative diseases .
One major bonus for ozone is that is it incredibly safe in today’s practice. In the early days, ozone could cause strokes and heart attacks because of gas embolisms when the ozone was administered incorrectly. The death rates due to ozone are .000007% which has the lowest risk of any treatments on the market today .
Ozone therapy has proven that oxidizing cancer cells, which are anaerobic, greatly diminishes their mobility, as well as destroying the cells it comes into contact with, making it a safe and non-toxic way to treat cancer. This treatment has been proven to provide beneficial chemical and cellular effects that have been the contributing factor to using hyperbaric oxygen as a primary therapy. Ozone is very cheap compared to the other cancer therapy methods and new techniques and researches should be carried out to develop ozone cancer therapy.

The World Dairy Expo had a tremendous amount of vendors, equipment, and valuable information. Some of the equipment I want to focus on are the teat wash products. Many of the large dairies have an anti-microbial sprayer, which is running a variety of anti-microbial sprays. The person milking usually sprays just the teat, and gives them a good wipe down before applying the milker. If the spray is applied too high on the udder, the milker will possibly suck some of the spray and “crud” as gravity flows down.
The new product is a brush that has an anti-microbial hose connected to it. The brush totally surrounds the teat, cleaning it like an automatic car wash. The brush is electrically safe, because it uses a 24-volt current. If a dairy is ozonating its incoming water to remove iron/manganese, it could use a small part of this water without any additional cost. We have an OSW-10 injection skid that could be easily matched up with an OZ-4AD ozone generator if you are not currently using ozone for any process. Ozone is a very good anti-microbial wash, so coupling with a brush like this could eliminate chemicals and save a lot of money.

The drinking water industry faces a number of questions as the regulatory and public communities become aware of the presence of compounds in water that were not previously detectable. With analytical advances over the past decade, several new classes of organic compounds have been identified.
Conventional treatment (coagulation plus chlorination) would have low removal of many Endocrine Disrupting Compounds (EDCs) or Pharmaceuticals and Personal Care Products (PPCPs). EDCs and PPCPs are emerging environmental contaminants that in very small concentrations may cause disruption of endocrine systems and affect the hormonal control of development in aquatic organisms and wildlife. PPCPs are continuously introduced into the environment and are prevalent at small concentrations , which can affect water quality and potentially impact drinking water supplies, ecosystems and human health.
The reuse of wastewater on agricultural lands may transfer these compounds to the soil environment. Due to the high polarity of these compounds, there could be leaches into the groundwater.
Existing strategies that predict relative removals of herbicides, pesticides, and other organic pollutants by activated carbon or oxidation can be directly applied for the removal of many EDC/PPCPs. But, these strategies need to be modified to account for charged (protonated bases or deprotonated acids) and aliphatic species. Some compounds (e.g., DEET, ibuprofen, gemfibrozil) had low removals unless ozonation was used. The addition of ozone substantially improves EDC and PPCP removals.

Ozone is both widely known and proven effective at limiting and eliminating biological growth, such as algae. The most logical and relevant way to use ozone within the bio-fuels industry would be in the cooling towers. Ozone can be incorporated into an existing system with minimal system modifications. Often, cooling tower water is treated with disinfectants such as chlorine and bromine, which are consumable and can be costly. Ozone can effectively reduce, if not eliminate, the need for these consumable chemicals within the cooling water loop. Ozone can be injected directly into the cooling tower or it can be injected into the influent stream. If any biological growth is present upon installation of an ozone system, the initial ozone demand will be higher than actually needed during continuous use. Since ozone is not biased, it will oxidize metals, rubber, and plastics if able to. This is a major concern and also explains the need for why the levels of ozone in a system should be monitored at all time. Ozone generation is an emerging technology that can be very useful and also cost-effective if it is utilized correctly and respected for being a powerful oxidizer.

Conventional flotation relies on floating of suspended solids on the top of liquid by air bubbles. A better separation effect is obtained when air bubbles are very small (micro-bubbles and nano- bubbles). In traditional dissolved air flotation (DAF) systems suspended solids and oily compounds are removed by coagulation, flocculation and removing the formed sludge by flotation by applying small air bubbles to increase buoyancy. Dissolved COD remains unaffected in DAF systems. By employing DOF, high concentration of ozone is available, which means a high potential of ozone oxidation and a high volume of micro-bubbles.
Schematic of a DOF system .
Dissolved COD remains unaffected and leaves a DAF with the effluent. When ozone is added to the air bubbles, it partially decomposes to highly reactive OH radicals, which in their turn oxidize the remaining dissolved COD. DOF removes non-biodegradable COD in a high level. As it is obvious in DOF systems, water quality parameters are removed by the two mechanisms of flotation and ozone oxidation. For this the reason, DOF systems have better efficiencies compared to DAF systems. It is estimated that DAF systems will be replaced by DOF systems especially in very polluted water systems to provide a one-step reduction of water quality parameters.
