Abstract –To day matter of concern is the production of
large amount of suchgases (like, CFcs, SO2, CO2) which
deplete ozone. As wecan’t stop the development and this
dovelopementis the need of the morden world therefore
wecan move to the sustainable dovelopement. For
attaining sustainable dovelopement, itis crucial to
dovelope such devices or module that can help the
environment from being deteriorate.
That iswhy the design of such module whichgenerate
ozone directly and
playsa vital role to
protectourenvironment. As we know that ozone
beingvery versatile and effective oxidising agent,
thereforeitisused in many of the industrial applications.
The basic principle of ozone generationis corona
discharge. This module consist of the necessarynumber
of devicessuch as, flybackinverter, controling circuit,
PIC microcntroller, for generating ozone gas at very
high voltage and high frequence of power supply.
The environmentaloxygencanbedirectlyconverted in to
ozone with the application of high voltage on the module

INTRODUCTIONS
Now ozone is being studied for number of
application some of them are-water treatment, for
domestic purposes, for industrial uses, in medical field,
with the use of ozone at very wide require the
improvement in the fundamental ozone generator.
Ozone is the second most useful oxidizing
agent which can be used for water treatment at
commercial level. However ozone gas has some
drawbacks if ozone is used in high concentration leads
to irritating the body.
Therefore the generation of ozone require a
technical improvement that is why it is very important to
study artificial generation of ozone gas. This paper gives
an evolution of ozone gas generator with technical
improvement .The high voltage and high frequency
circuit is implemented by using the principle of
switching A.C power supply.

The basic principle of generating ozone
depends up on spreading the molecule s of oxygen. We
can generate ozone gas based up on the equation-:
2O2+2O = 2O3.s
Fig. 1 Generation of ozone from corona discharge.
The important thing about the ozone is that it
can withstand a high level of voltage. Alonso et al
(2004) gives the concept of a low power supply and high
frequency for the generation of ozone gas. The results
were quite satisfactory for ozone generation using 1watt
prototype. As the concentration of ozone depends up on
the voltage at the outlet of corona effect generator, so
voltage must be constant.

WORKING
In this module of ozone generator we have used PIC
16F676 microcontroller .that is 8-bit microcontroller and
have 14 –pin. The 16F676 is directly connected to fan
and MOSFET driver IC2313that is basically used for
driving the MOSFET. Here we use IRF250 NMOSFET
that is very powerful MOSFET of low voltage and high
current. The output of MOSFET is applied to the high
voltage transformer, which is used to generate electrical
spark.
The main features of microcontroller, MOSFET, and
MOSFET driver are given below. The microcontroller
use in this module can execute instruction within 200
nanoseconds. Yet it is very easy to program (only 35
single word instruction) the CMOS flash based 8-bit
microcontroller is packed upon the microchips. powerful
PIC Microcontroller is a 14 pin package architecture
along with various features having 8 bit channel for the
10 bit analog to digital converter there is one comparator

RESULT AND DISCUSION
As per the analysis ozone gas generator has very wide
area of application in many of the industries. There is a
great need of ozone generator in some industries which
have to keep the fruits and vegetables fresh. The another
aspect of ozone generator is that now this module also
used in water treatments for removing the dirt and
microbes from the water . So a fresh usuable water can
be obtained with minimum investment with the help of
this ozone gas generator.
The ozone gas generator model produces ozone for
cleaning air or removal of smoke from air. From the
result of previous work it is found that the previous
ozone gas generator module can produce 3g of ozone
per hour.
Humidity, atmospheric pressure, temperature, moisture
content in the air also plays a vital role in ozone
generation. When we studied the chemical behavior of
ozone gas it is found that the ozone gas is “PUNJENT”
when inhaled. So while running the ozone gas generator
it is one of the way to represent the presence of ozone
gas.

CONCLUSION
The operation and design of ozone generator
and subordinate equipment is very detailed and complex
subject, however paper is intended only to give a brief
overview of current thinking and technique for safely
producing and using the unique oxidant for hydroponic
application. The ozone has its very useful application in
treatment of water .The ozone is also uses for industrial
sector, effluent water treatment, food processing.
When the ozone generator is designed
correctly. it will provide a reliable and safe source of
ozone,however it should be kept in mind that ozone is a
toxic gas , therefore equipment and installation , if
incorrectly designed and operated, can present Signiant
danger to both plants and animals. For the installation
recommendation of the related or familiar organization
is needed.
