3. ACKNOWLEDGEMENT
We are gladly & thankful to Director as well as
Principal Dr. H. M. Nimbark and Head of the Departments Prof.
H. H. Gajera and our faculties who gave us a great guidance
regarding training and instructed us the importance of training in
civil field. So we decided to take visit in water treatment plant
which is situated in jetpur.
We are especially thankful to Mr. Gondaliya, the in charge
officer of water treatment plant because he granted us permission
for taking visit at treatment plant and gave the proper guidance to
students and allow to visit for the practical based approach
learning to students.

4. GENERAL INFORMATION
Jetpur Dyeing and Printing Association have set up a Common Effluent
Treatment Plant [CETP] at their location in Jetpur, Gujarat, India. The
association has set up a common effluent treatment plant to treat the
effluent arising from around 200 washing Ghats. The CETP consisting of
physico-chemical treatment is designed and commissioned by CA to treat
2000 cu.m/day of effluent with inlet BOD 180 mg/L. The total cost of
these textile industries project was Rs. 3 Millions and the plant was
successfully commissioned in 1991 to give treated effluent BOD < 100
mg/L.

5. PURPOSE OF VISIT
Our main purpose for this visit is to be familiar with industrial
environment and to get practical knowledge of water treatment
plant components.
Also in 6th
semester subject like water and waste water
engineering requires knowledge about how polluted water is being
treated, so it is very much convenient to see all the practical and
components in real time work environment.

6. WHAT WE LEARN?
On 7th
February, 2015 (Saturday) at 09:30 a.m. we reached at
common effluent treatment plant at jetpur. The visit started from
the initial tank where the waste water of city and industries is
collected. Then that flow is collected from the inlet pipe and
removes the larger solid inorganic material such as paper, plastic,
etc. by the rotating chamber.

7. Mr. Gondaliya, the incharge officer of water treatment plant
guided all the students about the entire process of water treatment
plant.
First unit of water treatment plant is screening Mr. Gondaliya the
incharge officer of water treatment plant provide basic information
about screening process of waste water treatment plant.
The collected waste water is transported to Preliminary treatment
chamber; wastewater is then passed through a primary
sedimentation tank where solid particles of organic material are
removed from the suspension by gravity settling. The resultant
settled primary sludge is raked to the centre of the tank where it is
concentrated and pumped away for further treatment.

8. The next step of the treatment process is secondary clarifier. The
water from the primary tank is transported to the secondary
clarifier for adding chemicals such as lime and alum to reduce the
PH of water.

9. The next stage is a biological process which breaks down
dissolved and suspended organic solids by using naturally
occurring micro-organisms. It is called the activated sludge
process.
The settled wastewater enters aeration tanks where air is blown
into the liquid to provide oxygen for mixing and to promote the
growth of micro-organisms. The “active biomass” uses the
oxygen and consumes organic pollutants and nutrients in the
wastewater to grow and reproduce.

10. Some of this sludge is recycled to the inlet of the aeration tank to
maintain the biomass, hence the name for the process – activated
sludge. The remainder is pumped to anaerobic digesters for further
treatment.

11. All the students were in hurry and in excitement for knowing the
next steps of water treatment. The next steps for wastewater
treatment plants use disinfection for tertiary treatment to reduce
pathogens, which are micro-organisms which can pose a risk to
human health. The sludge is passed to the sludge handling system
which contains 20% sludge and 80% water.
Now again to remove the sludge particles the water is passed
through the belt filter press.

12. The purified water is obtained by chemically treating the water
coming out of the belt filter press.

13. Mr. Gondaliya has little smile on his face by watching full of
attention of all students and then he explains the detail process of
tertiary treatment.
In which Chlorine is usually dosed into the treated wastewater
stream for disinfection. However, uses large ponds in which
sunlight and other micro-organisms reduce the pathogens.
Although the PH of water is reduced and sludge content and other
impurities are removed, still water is not obtained in purified form
as it contains the coloured water.

14. CONCLUSION
From this visit, we get the information and practical
knowledge about the physio-chemical treatment of waste water
and components used in treatment plant. Some test should be
performing for general discussion with experts in the industry.
About 59 students were benefited. The visit was nicely completed
with group photography at 12:00pm.
