Disinfection, purification water air surfaces by
ozone, oxygen, hydrogen - O3 O2 H

How does it work?

Let's not confuse the ozone layer, which is necessary for life on Earth because it protects us from the sun's UV rays and oil pollution.

Pollutants in the air, nitrogen oxide and organic particles from road traffic and factories, cause abnormal concentrations of ozone when the weather conditions are about to change.

In this case, the source of the problem is not ozone, a natural phenomenon, but hydrocarbons.

Ozone has been used in France for more than 100 years to disinfect waste water.

Ozone has been recognized worldwide for the preservation of food products for decades and has been invested with a double-digit growth in multiple fields of activity: tertiary, agricultural, wine, food processing...

Its overpower is world renowned for destroying bacteria and viruses with very short contact times, leaving no residue. It destroys bacteria and viruses by the principle of lysis unlike chlorine which kills bacteria without destroying them. Consequence: Ozone destroys the biofilm.

The presence of ozone in many areas is the result of technological developments, technical understanding and the willingness of many stakeholders to adopt less polluting production protocols.

Ozone occurs naturally outdoors at a concentration of about 0.03 ppm.

The French National Institute for Research and Safety (INRS) stipulates that an employee must not be exposed to an ozone concentration higher than 0.1 ppm for 8 hours or 0.2 ppm for 15 minutes.

Defined common units of measurement

Before discussing the production of ozone generators, the measurement of dissolved ozone in water and many other important information about ozone, we must clearly define the units of measurement used in the world of ozone. There is some jargon and assumptions of established knowledge in the "ozone world", so take some time, read below and make sure we are speaking the same language.

Ozone generator output units

g / h = gram per hour

The most common measure of the overall output of the ozone generator. This measures the weight of ozone in grams that is produced in one hour by the ozone generator. To make this determination, the flow of gas through the ozone generator will be required, as well as the quantity of that gas which is ozone. This will give sufficient data to provide an estimate in g/h.

mg /h = milligrams per hour

Commonly used to measure the production of smaller ozone generators. 1 g / h of ozone = 1,000 mg / h of ozone.

kg / h = kilograms per hour

Used to measure the production of very large ozone generators. 1 kg / h of ozone = 1,000 g / h of ozone.

lb / day = pounds per day

Used to measure the production of large ozone generators in English units. 1 lb / day of ozone = 18.89 g / hr of ozone.

Ozone concentration units

w t% = percentage by weight

This is the percentage of ozone gas in a given volume (as opposed to volume). This provides a concentration of ozone gas in the gas flow through the ozone generator.

g /m3 = grams per cubic metre

Best method for quantifying the ozone concentration of an ozone generator. This will provide the grams of ozone present in a given cubic metre of feed gas through an ozone generator.

ug / ml = micrograms per millilitre

Used to measure ozone concentration in certain applications. It is the same as g / m3. 1 ug/ml ozone = 1 g / m3 ozone.

ppm = parts per million

Used to measure the concentration of ozone in ambient air. Quantifies parts of ozone gas in every million parts of other gases (normally air). 1 part of ozone in 1 million parts of air will be 1 ppm. Note: ppm can be measured by weight or volume. In ozone, global ppm is almost always measured by volume.

Also used to measure the concentration of ozone in water. 1 ppm = 1 mg / I of ozone in water.

ppb = parts per billion

Measures low levels of ozone in ambient air. 1 ppb = 0/001 ppm.

mg / I = milligrams per litre

Normally used to measure ozone in water. 1 mg / I = 1 ppm ozone in water.

Can also be used to measure the concentration of ozone in the air. 1 mg/ I ozone in air = 1 g/ m3 = 1 ug / ml = 1 gamma. These are all used interchangeably.

Flow measurements for feed gas (air or oxygen)

LPM = litres per minute

Metric measurement of feed gas flow through the ozone generator. Sometimes indicated in L/ min. This can be oxygen or air flow. 1 LPM = 2.1 1 SCFH

SCFH = standard cubic feet per hour

English measurement of feed gas flow through the ozone generator. This can be oxygen or air flow. 1 SCFH = 0.47 LPM

m3 / h = cubic metres per hour

Metric measurement of feed gas flow through the ozone generator, mainly used for large scale flows and ozone generators. This can be oxygen or air flow. 1 m3 / h = 16.66 LPM

Disinfection measure

Disinfection rate

LOG1 = 90% LOG2 = 99% LOG3 = 99.90% LOG4 = 99.99% LOG5 = 99.99% LOG6 = 99.90% LOG7 = 99.99
