What is Ozone?
Ozone is an allotropic form of oxygen with
each molecule contains three atoms of oxygen instead of the standard
two. Ozone is formed naturally in the atmosphere, by lightening discharges
giving the air its characteristic fresh and clean smell afterwards.
How is Ozone produced?
Ozone is produced by a method called corona
discharge, A high voltage is passed across a gas stream containing
oxygen. The energy of the high voltage splits an oxygen molecule
(02); into two oxygen atoms (0) - which recombine with ordinary
molecules of oxygen (02) to form ozone (03).Ozone is also formed
in the proximity of certain types of ultra violet lamps. The short
life of ozone means that it cannot be stored and transported hence
it is produced on site for immediate use.
How does Ozone Work?
Ozone is the most powerful oxidising agent
besides fluorine. It is 51% stronger than chlorine and has a kill
rate of 3.125 times faster Ozone readily oxidises organic material
in bacterial membranes which weakens the cell wall and leads to
cell rupture causing immediate death of the cell. Ozone oxidises
most organics to carbon dioxide and water, while reducing many inorganic
materials to a biodegradable state.
Does Ozone work on Microbes
Ozone will kill all bacteria, viruses, spores,
mould, mildew, fungi, amoebae and cysts. The concentration , the
composition of the host environment and the contact time of ozone
with the organism determines how effective ozone is on the organism.
Is Ozone Safe?
High concentrations of ozone can cause irritation
of the eyes, dryness of the throat and cough. Hence modern systems
doses the ozone into water with the intention of building a residual
level. Ozone can be detected at levels ten times smaller than the
(0.1ppm continuous exposure over 8 Hours) current Health & Safety
Guidelines, hence escaping ozone can be easily detected. |
