How effectively does an Ozone Generator remove odors?

Introduction

Ozone has for a long time now been considered as an excellent purifier because of its high oxidation capabilities. Ozone is made up of three atoms of oxygen and is odorless and unstable. As an oxidant, the extra molecule of oxygen attaches itself to the cells of the pathogen, destructing it by altering its structure and composition chemically, and completely destroying it without giving out any offensive odor. The human nose can distinguish about 10,000 types of smells, thanks to the millions of neurons that make up the olfactory epithelium responsible for our sense of smell. This is important to understand since odors are not always pleasant. You also have pungent odors, some are extremely offensive, and some odors like strong perfumes can even trigger a nasty headache. So most options ask for masking or temporarily doing away with the bad smell, but they do not necessarily eradicate it.

Ozone, with its powerful oxidizing capabilities, almost three-thousand time more capable than its lesser cousin, chlorine, makes it a formidable choice. Also remember the distinction between the benefits of ozone in the upper atmosphere that protect humans from ultra-violet rays and ozone at ground level that mixes with air pollutants to create smog.

How effective are ozone generators in odor removal?

Ozone generators became popular after the benefits of ozone became evident across the globe. Also, since ozone is short lived, it needs to be produced onsite at the location where it needs to be treated for it to be even effective. Ozone generators are ideal for killing mildews, bacteria, getting rid of odors, and molds. They can even remove body odor including odor left over from cigarettes, food, or pets.

Ozone generators should typically be used in sealed spaces or where there is no habitation, or move the habitation outside until the treatment is done. This is because ozone gas beyond a certain level can be toxic and within the normal levels, it may not necessarily be effective. This is so because of the shock treatment that is induced to kill molds, which requires high ozone levels and the generator also has to be kept running for 30 minutes, though overall, there may be a better cost efficiency. Portable generators are used during travel. You may not realise the even in supermarkets, ozone is probably used at low levels, enough to eliminate any odors and preserve food and vegetables.

Even after treatment, you may have to wait for an hour or more before moving back into the space. However, ozone also has its limitations. It cannot permeate non-porous products such as wood. Ozone generators may not be the best choice for removing pollen, allergens, or dust. Research also indicates that ozone may not be able to eliminate carbon monoxide effectively. Further, it is difficult to measure the quantity of ozone that is produced due to the combination of elements. For example, the concentration will be different in an enclosed space versus an open space. Further, the furniture or other materials inside the space also have their own reaction to ozone and hence its overall effectiveness.

What to look for in an Ozone Generator

Introduction

It is common knowledge in recent times that ozone is used as an alternative to chlorine for treating contaminated water or cleaning pools due to is high oxidation capability. It is also used as an indoor air purifier to remove allergens and other pathogens including the removal of moulds. However, are you also aware that ozone therapy is used in the field of medicine to improve the body’s immune system and capability to intake oxygen? Given ozone’s short shelf life before it reverts to its original state, that is oxygen, it is necessary to produce ozone on site for it to be effective.

Ozone generators were manufactured to help address this requirement. These ozone generators play an important role in ozone therapy. Given that there are a number of ozone generators to choose from in the market today for both commercial and residential use, it is crucial to understand what to look for in an ozone generator before purchasing one.

What to Look for in an Ozone Generator?

The history of ozone generators dates back to 1857 and over time there were many different types of generators that were developed. Today with the popularity of ozone therapy and its effectiveness in other areas, there are much more diverse types of ozone generators that have flooded the market. Ozone can be produced using these generators in a number of ways, popular among which is the corona discharge and ultraviolet radiation. A consideration to think about before making a purchase is the design of these generators, along with other drivers such as quality and units. The common design components in most generators include the power switch, a fan to drive out the gas out of the unit and finally, the source from where ozone will be generated such as the one mentioned earlier, the corona discharge or ultra-violet radiation.

The reason design has a direct impact on the unit maintenance. Also understand that size of the generator does not tie up with quality. On the contrary, check for the capacity. The question you should infact be asking is how much ozone the unit will deliver. We are talking value for money. The corona discharge is believed to produce a higher amount of ozone for the investment. When a ozone manufacturer does not advertise the output an unit can produce, then you should reconsider buying that generator type or probe more to understand why that is not stated since it is a crucial buying factor and it also means that the treatment time is considerably less. This ties up the quality factor also.

For ozone to be effective, it must be produced at levels known as shock treatments, which the corona discharge produces. So it’s a cycle. Another aspect of the design is the gas distribution while using a single fan and alternatively using two fans. Ozone is heavier than air, so it is understandable that a single fan may not be effective and will require additional fans externally. Finally, consider the cost for housing the unit itself.

Are Ozone Generators Effective in Controlling Indoor Air Pollution?

Introduction

Ozone a powerful oxidant has been much touted for its benefits compared to its other alternatives for water treatment and air treatment, where use of ozone is most popular. Ozone is a powerful oxidant which lasts on site for a very short period of time before rolling back to its original state as oxygen. After all, ozone comprises three molecules of oxygen. You must understand the distinction between ozone present in the higher reaches of the atmosphere and the presence of ozone in the lower areas. The former, found in the stratosphere protects us from the harmful effects of ultra violet radiation. The latter known as smog causes breathing problems and other associated health issues. The advantages of ozone have been advertised by manufacturers of ozone generators who package it as activated ozone. However on the contrary, much has been discussed about the effectiveness of ozone in controlling air pollution.

Effectiveness of Ozone Generators

Ozone generators became a popular choice for indoor air cleaning. Since ozone has to be produced onsite under specific conditions and lasts for a short time, ozone generators came into production. Ozone generators are marketed and sold as air purifiers since they produce ozone. However, the scientific evidence points in the other direction and is also accepted by health professionals. Terms such as mountain fresh air, energized oxygen, saturated oxygen are commonly used to describe ozone generators, which are sold as air cleaners. While there is not hard data on the side effects on the use of ozone to treat pollution, research indicates that ozone is not very effective as an air purifier. While the presence of specific volatile compounds did show a decline, however, overall it did not seem to have a positive effect.

Further, the concentration of indoor ozone air purifiers is not at the required level to kill molds and bacteria or neither does it remove any particles in the air such as dust or pollen for example. Any higher level will actually be harmful for humans and other inhabitants in such residential places. In any case, there is a possibility that the level of indoor ozone production has an adverse effect since it is not at an optimum level. Most members of the public are also not aware that ozone generators induce far reaching chemical reactions that result in the production of more pollutants that affect the individual’s health. So inhaling ozone can lead to lung irritation and cause damage, and even at what is considered low levels of ozone can still cause chest irritation, breathing problems, and even chest pain.

Ozone is also highly reactive. So it also reacts negatively with a number of harmful by-products. Though ionizers are introduced in certain varieties of ozone generators, even these have been found to be not as effective in experiments. In fact in some countries, there are regulations to regulate the level of ozone production. In extreme cases, when ozone is used to cleanse or decontaminate indoor spaces in buildings, there is a huge possibility that will result in secondary obnoxious ozone odors that may be emitted.

5 Must Know Facts about Ozonators

Introduction

Activated oxygen most commonly known as Ozone is one of the most powerful disinfectants in the world that is widely used to kill harmful pathogens, bacteria, and bad odors. Ozone is naturally present in the atmosphere through ultra-violet rays that protects humans from harmful ultra-violet radiation. One of the easiest ways it is naturally created is when lightning occurs during thunderstorms. However, the ozone present in the ground level is considered dangerous for humans and can lead to a number of respiratory issues. The good ozone, though is a powerful oxidizer lasts for a very short period of time. It makes contact with the pathogens and destroys it through the oxidation process and reverts to its natural state, oxygen. Hence a need was identified to produce ozone onsite through ozone generators.

Facts About Ozonators

Ozonators, ozone machines, or ozone generators have been in vogue to harness the benefits of ozone in treating spas, water treatment plants, sewage treatment, swimming pools, indoor air, odors both in commercial and residential areas. Ozone is also used in the Food industry to keep food fresh. Ozonators are marketed as activated oxygen or air purifiers to purify the quality of indoor air. Ozone can be produced through corona discharge or ultra-violet radiation. While the benefits of ozone generators have been hugely touted, there are many disadvantages to using them which has been widely debated. In many provinces in the United States, there are strict regulations on the quality of air purifiers that can be sold in the market to ensure that ozone levels are not produced beyond the expected levels. Given the mixed reports, it is important to research the ozone generator of your choice before making the final purchase.

One of the biggest claims made by manufacturers is the ability of the ozone generator to cleanse polluted air. This is based on ozone’s ability to attach itself to the pathogen and destroy it. However, there is no clear evidence to support these claims. In the case of treating molds, ozone is required to be produced at unsafe levels to humans and hence ozone treatment is not recommended as an effective treatment for controlling molds. Similarly, while eliminating odors, while ozone is considered effective since it destroys the source, it has to be produced at levels exceeding 6 ppm, known as the ozone shock. This is because it is only at this level that ozone is at its maximum best. Ozone used in air treatment while effective in purifying the air does not remove allergens and is believed to be not very effective in the treatment of gaseous pollutants. Before you buy the generator, check for certifications such as NOAI approval and ratings to ensure it is of standard quality.

Alternatively, you can also try simpler solutions before resorting to an ozone generator. Keep the house well ventilated to improve air circulation. Second, ensure there is no source of pollutants around the vicinity. You can also consider using air purifiers that are non-ozone based.

The Unconventional Guide to Industrial Ozone Generators

Introduction

Ozone is produced in the atmosphere by trapping the sun’s heat. The oxygen molecules are broken down through the sun’s ultra-violet (UV) radiation. This is also known as  where ozone is produced naturally through the chemical reactions between the UV rays and oxygen. However, ozone in the atmosphere lasts for a very short time and quickly dissolves. The latter is known to be an effective disinfectant for water treatment including swimming pools, and considered more effective than its popular alternative, chlorine.

Ozone is a very strong oxidant and is capable of destroying harmful pathogens, including odors and smoke. It is also used indoors to purify the air and surrounding environment. Ozone is also approved in food processing and pest management to remove contamination. Ozone generators were manufactured to produce ozone for a sustainable time and realize the benefits of ozone. Air cleaners on the other hand do not offer these capabilities.

Industrial Ozone Generators

There are many varieties of ozone generators or ozonators available in the market that produces ozone on location. The most common method of producing ozone includes the electric corona discharge and the use of ultra-violet irradiation of dry air. Industrial and commercial institutions including hotels, restaurants, condominiums, homes and hospitals to name a few examples, use odor-free industrial ozonators, also known as industrial ozone machines. In fact, because of its odorless, cleansing property, people might welcome the use of ozone in closed spaces rather than chemical deodorizers that can irritate the senses.

Further, a building can become odor free within a short period of time. Industrial ozone generators are also widely used in large water sewage treatment, including sanitization of liquids. Ozone enters the cell structures, breaks it down completely through the oxidization process. Moreover, because it is odorless and does not form organochlorine compounds, ozone is even directly produced in bottled water.

Industrial ozone generators offer a wide variety of benefits such as their ability to quickly remove odors without leaving any chemical deposits; comparatively safer due to its faster conversion time to oxygen; destroy molds and microorganisms in damp environments; last, but the not the least, ozone improves the quality of air in the environment in which it is used thus improving health and safety standards.

There are many types of industrial ozonators available in the market for different uses. The UV based ozonators are considered to have a better capacity to produce output in different humidity conditions while the corona dischargers experience a reduced production of ozone even under moderate humid conditions. The reduction is almost 40%-70%.

In terms of maintenance, UV ozonators are far more easier to handle and is literally non-existent. In comparison to the corona discharge type of ozone machines, UV ozone machines are considered more stronger and do not leave any other discharge such as nitric acid. There are recommended type of ozone deodorizers depending on the reason for which they are being used. For example small rooms in hotels can use DC PRO 450 or larger rooms can use PRO-3400.

Ozone Generation For Swimming Pool Disinfection

Ozone has been used in swimming pools and spas in European countries since the early 1950s and in the United States since about 1975. In India, the use of ozone has grown rapidly over the last decade. Numerous private, public and commercial pools have switched to ozone technology as people have become more concerned about chlorine and chlorinated byproducts.

Chlorine is a good sanitizer and oxidizer, but these processes create unpleasant and unhealthy by-products. When chlorine oxidizes organic contaminants (body wastes, soaps, cosmetics, etc) carcinogenic chlorinated organics (THMs) are produced in abundance.

Chlorination of nitrogenous body wastes result in chloramines which cause an unpleasant smell and are the source of stinging eyes, ear and skin irritation. Despite these studies, most swimming pool ozone managers are probably unaware that they are exposing their patrons to THMs.This problem is not widely known and for the most part is ignored by the media.

Ozone prevents the formation of scum line forming and filter clogging chlorinated organics, eye & skin irritating and hair and swimsuit discoloring chloramines. Upon completion of these signficant oxidation tasks, ozone reverts to oxygen, leaving no by-products behind.

To date, Ozonation is the best water treatment solution available, yielding the most modern, safest and most environmentally friendly sanitation of pools and SPAs. However, not all ozone generation techniques will achieve the above benefits in a swimming pool.

There are two basic methods for ozone generators; corona discharge (CD) method and ultraviolet radiation (UV) method. In practice, ozone is generated by passing an oxygen containing gas through either a high energy electrical field or a high energy radiation source, the former being corona discharge and the latter UV radiation.

Only a portion of the oxygen is converted to ozone by these production techniques. With corona discharge an ozone concentration of up to 13% by weight is obtainable, however when generated by UV radiation a concentration of only 0.001 – 0.1% by weight is obtainable.

As expected, the solubility of ozone increases with an increase in ozone concentration in the gas stream. According to Henry’s Law, the efficiency of absorbing a specfic gas into an aqueous phase is based on the partial pressure of that particular gas in the total gas flow.

Therefore, the higher the concentration of ozone in the generator gas stream, the more complete will be the transfer of ozone into the water treatment. For UV generated systems, the ozone solubility is nearly nil. Hence, for ozone treatment of swimming pools, CD generated ozone will provide a water quality that is not achievable with UV generated ozone.

From a scientific and regulatory perspective water disinfection is routinely characterized on the basis of contact time as ascertained by Chicks law. Contact time and its kinetics are simply a measure of the inactivation expressed as a function of concentration of the disinfectant and time (as C*t, C is residual concentration, and t, time).

As expressed earlier, the concentration of ozone through UV generation method is 1/20 that of CD generation method. In addition to this, most UV lamps used for disinfection purposes operate in the 254 nm range. The ozone produced in the process gets decomposed by UV radiation to form hydroxyl radicals.

The half-life of hydroxyl free radicals is on the order of microseconds and have very little time to complete disinfection ozone action which typically require longer contact times. As a result hydroxyl radicals have oxidizing properties, but no disinfection property.
