MY PARENTS
ACKNOWLEDGEMENT
It gives me extreme pleasure to place on record indebtedness and
sincere gratitude to ER. IMRAN AHMAD (Lecturer), Department of
Civil Engineering, Integral University, Lucknow whose excellence
guidance, helpful comments, timely suggestions, constant
encouragement, stimulating discussion and constructive criticism
have enabled me to complete this project.
Words failed me, when I think of all, that my parents have done
for me. Throughout my life they have always been a constant source
of inspiration and whose constant admonitions help me in my
academic pursuit. Their sacrifice, prayers and good wishes made me
to reach this stage. I salute them.
I sincerely thank ER. SABIH AHMAD (Head & Professor) who has
been continuous source of aspiration to me.
I am highly indebted to the teachers and lab staff of this
Department for their support.
I wish to thank our entire project partner for their kind
encouragement during our work.

PREFACE
We feel great pleasure and gratitude in submitting the project.
It requires modern and good knowledge of recent theory to help in
making the project more economical. In this project we have
explained the term dissolved oxygen, importance of dissolve oxygen
for human being and aquatic life and also its significant role in
environment. We have also explained phenomenon of DO mixing with
water. This project also includes the different process of
determination of DO in contaminated water sample and lab test. We
had also performed an experiment by Winkler method to find DO of a
sample in University. In this experiment had used a redox
(reduction-oxidation) titration to determine the amount of
dissolved oxygen in water samples. It is often done in conjunction
with a precipitation titration to determine the amount of chloride.
For both titrations, the reactions occurring with the dissolved
oxygen and chloride will result in color changes, therefore
providing a natural end point indicator and finally gives the
DISSOLVED OXYGEN.
I am heartily thankful to my teachers especially all faculty
member of civil engineering department for their cooperation.
Without their guidance the completion of the project would have
been impossible.
The experience we have gained by putting our hard work in an
environment of almighty, cooperation will certainly serve as means
of encouragement in future.
