What is Ozone?




OZONE occurs naturally  in atmosphere due to absorption of light particles and subsequent photochemical reaction of oxygen particles.​

Ozone also forms Naturally when lightening strikes the electrical discharge breaks  molecules of  oxygen  into free oxygen atoms which again combines with oxygen to form a tri atomic ozone where a fresh form of smell generated  due to this action.

Ozone  present at  stratosphere protects us  from harmful uv radiation generated from Sun
and to an lesser amount in troposphere.

Its reactive oxidizing property  aids in purification of air, acts as sterilizing agent and also has better bleaching properties.

Ozone‘s strong oxidizing properties helps in disinfecting  and sanitizing  is  ecofriendly much better than harmful chlorine based disinfecting agents.

Lower limits of ozone concentration are not  harmful to humans and animals but  can be toxic to Microorganisms and bacteria.

Ozone is unstable in  nature  because ozone decomposes in to oxygen over time

Collective ozone properties can be put into fruitful uses  where there are numerous  application in all fields  where disinfection, water treatment is the need and Ozone does this effectively.

Only Oxygen and power is required and ozone is generated onsite. Since ozone can’t be stored due to its unstability.
Ozone generation requires oxygen

First atmospheric air fed ozone systems results in generation of  less ozone concentration but also along with harmful nitric based byproducts will be generated due to nitrogen content  in atmospheric air. These air fed can be used for light application like air purifiers and sanitation in hospitals etc.

Second oxygen fed ozone systems results in generation of  high concentration ozone with trace amounts
of nitric compounds . Oxygen fed systems are used where mild to severe waste water needs to be treated.

When choosing Ozone  based treatment ozone resistant materials are to be taken into account.
Contact time along with better mixing mechanism with liquid should  be  maximum for credible ozone mass transfer.

Higher limits of ozone concentration ensures dissolution of ozone properly  and effectively where  water needs  to be treated.

The Smell of Ozone

Ozone at low concentrations (0.01 - 0.04 PPM) leaves a fresh and pleasant smell to a room. 
Higher concentrations exhibit an “electrical” odour. This is typically smelled after a strong lighting 
or rainstorm.

Half Life

As soon as ozone is formed, it starts to decay to oxygen. The half life is 2½ to 7 minutes 
in most applications, depending on the ambient conditions. In cool, sterile environments the 
half life can extend to 60 minutes. Higher temperatures lead to shorter half life.
