3. Topic to be covered in this presentation
 Introduction
 Objective of the study
 Methodology
 Design of the Plant
 Results and discussions
 Conclusions and Recommendations

4. Introduction
 Existence of iron in ground water is a common phenomenon in
many areas of rural Bangladesh.
 Because of the problem villagers who lives under the poverty line
are not able to use iron free safe water. For this sometimes people
face serious health problem.
 A new Iron Removal Plant is designed and constructed and tested
quality of water in this study.

5. Objectives of the study
a) To collect 5 tubewell water and analysis physical and chemical
properties.
b) Design a homemade iron removal plant and connect it with the
iron concentrated tubewell.
c) Analysis the treated water quality and compare with the raw water
and Bangladesh standard.
d) To draw few conclusions and recommendations based on the
study.

6. Methodology
Site survey:

7. Methodology cont.
 Collected 5 Tubewell water.
 Test of drinking water parameters including iron concentration
for the raw samples.
 Design a Iron removal plant.
 Determination of cost of the iron removal plant.
 Test of drinking water parameters including irons for the
treated samples.
 Compare with Bangladesh standard.
Parameter tested are as follows
 pH, Color, Turbidity, Alkalinity, Hardness and Total Solid.
 Measurement of Iron concentration.

8. Design of the
Iron Removal Plant

9. Design of the Plant

10. The Plant consists of
 A terracotta vessel.
 Brick chips.
 Sand
 Charcoal.
 Bamboo
 Clean cotton cloth and
 Plastic bag.

11. Construction on the plant

12. Construction of the plant cont.

13. Construction of the plant cont.
First step- Place a clean
cotton cloth in the vessel
Second step- Two inch of
clean brick chips placed
on clean cloth

14. Construction of the plant cont.
Third step- 1.5 inch sand
layer on brick chips
Fourth step- 1.5 inch
layer of charcoal

15. Construction of the plant cont.
Fifth step- apply 1.5 inch
sand layer on the charcoal
layer
Sixth step- apply 1.5 inch
brick chips layer on the
sand layer

16. Construction of the plant cont.
Iron Removal Plant Developed by us
Considerations:
• Every layer of the materials used in
the plant should be compacted tightly.
• During construction of the plant one
should be careful so that the terracotta
vessel does not crack.
• First 40 liter of water is not acceptable
for drinking and cooking purpose

17. Cost determination of the
iron removal plant.

18. Determination of cost
Items Price
Terracotta vessel 80.00/-
Bamboo 45.00 /-
Brick chips 50.00 /-
Sand 30.00 /-
Charcoal 15.00 /-
Clean cotton cloth 30.00 /-
Plastic Bag 5.00 /-
Total cost 255.00 /-

22. Performance of the developed Iron Removal Plant:
o On an average the iron concentration decreases substantially
after filtering water through the developed plant. And the value
is within the prescribed limits of Bangladesh.
o 98 % iron is decreased after the filtering process.
o The existing iron concentration is found on an average 0.30
mg/l and that lies in the acceptable limit.

23. Performance of the developed Iron Removal Plant:
Comparison of different water quality parameters before and after the
filtering process.

30. Performance of the developed Iron Removal Plant:
Summery of the results of other water quality parameters test
 The Color is found decrease 97.10% on an average.
 pH is found increased and it came to the Bangladesh standard limit.
 Turbidity is found decreased by 99% on an average.
 Alkalinity and Hardness are also decreased but in some cases, it is seen that
the alkalinity and hardness are increased because of the materials we used.
But still the hardness is within the Bangladesh standard limit.
 There are no trace of arsenic is found in our collected samples.

31. CONCLUSIONS AND
RECOMMENDATIONS

32. CONCLUSIONS
 A total 9 liters of water can be applied to our constructed plant. But it depends on the
size of the vessel. It takes 45 minutes to complete filtering the whole 9 liters of water.
 An iron removal plant with a gravity flow system, used coarse media (brick chips),
sand, charcoal can remove almost 99 percent of iron from tubewell water without being
cleaned upto 3 months.
 Other tested water quality parameters are satisfactory for drinking water.
 Total cost is determined for the plant and it is 255 taka.
 Although the cost of the ingredients is very low but the people of the village have
available of all the ingredients.

33. RECOMMENDATION
 People who suffer much from Iron in the drinking water and those who are
not eligible to install and maintain an electric filter are being recommended
to use the iron removal plant we developed.
 Though it is eligible to produce iron free safe water to drink and use in
cooking purposes, but it is slow in filtering process. So it is recommending
for further studies so that it can be convert to faster process of filtering.
 We could not have tested BOD, COD and TC-FC because of the pandemic
of COVID-19, the tests are being recommended for the further study.
