  4. OUR TEAM • GAUTAM KALITA. • MRIGANKA SEKHAR KALITA. 4

  5. OUR AIM • To rediscover pure drinking water from pond water. • To remove the access chemical elements which we have found. Our process should be effective in Earth base , Lunar base, Mars base. 5

  6. OUR PROCEDURE IN BRIEF BRAIN STORMING RESEARCHING THE PROBLEM CHOOSING ONE DESIGN DEFINING THE PROBLEM BUILDING THE MODEL COMMUNICATING TESTING THE MODEL 6

  7. Before our experiments. ( WATER QUALITY ) CHEMICALS QUANTITY TURBIDITY (NTU) 24.0 pH Value 10.26 IRON (mg/ lt) 5.84 0.51 FLUORIDE (mg/ lt) HARDNESS (mg/ lt) 220.0 75.0 CHLORIDE (mg/ lt) 7

  8. Before our experiments ( water quality on the Graph Drawing ) 8

  9. Remarks of the poor quality water • The water is not for drinking purpose. Neither anybody prefer for drink. Our team build a model to find out pure drinking water from this poor quality water. We describe the model here. Group meeting Water sample 9

  10. Approaches Rediscover a pure drinking water By Chemical method. 10

  11. A. Experiments with chemicals. 1) Materials used Ash of banana tree Soft sand Activated carbon Salt Banana tree. Rough sand of Subansiri river. Pebbles Stones of Arunachal Pradesh Kolakhar ( prepared from ash of banana tree.) 11

  12. A. Experiment with chemicals. 2) Apparatus Filter paper Plastic jug. Blade Pipe Hanger Burner 12

  13. Materials and It’s Quantity in the chart Materials Quantity Activated carbon 20 mg/lt 500 gm/lt Pebbles Stones 750 gm/lt Salt 5 mg/lt 8 ml/lt Kolakhar Soft sand 250 gm/lt 200 gm/lt Rough sand Lime 4 mg/lt 13

  14. A. Experiments with chemicals 14

  15. Result from the working model. ( Experiments with chemicals ) (Water Quality) Chemicals Quantity Turbidity (NTU) 9.8 6.1 pH value Iron (mg/lt) 0.11 Fluoride (mg/lt) 0.12 Hardness (mg/lt) 20.0 Chloride (mg/lt) 4.0 15

  16. Result from the working model 16

  17. Design of the working model (OUR SYSTEM) Storage tank with Kolakhar Filter paper Drinking water tank Salt Soft sand Lime Activated carbon Filter paper Rough sand Stones Pebbles 17

  18. Design of the working model Storage tank Iron, turbidity ,hardness, fluoride, chloride remover. Bactaria remover Water tank 18

  19. Design of the working model (Components of the moel) • Storage tank with Kolakhar. • Soft Sand. • Activated carbon. • Rough sand. • Pebbles. • Stones. • Filter paper. • Lime. • Salt. • Filter paper. • Water tank. Iron, Turbidity, Fluoride, Chloride ,Hardness remover. Bactaria remover 19

  20. About our model This model should be effective in Earth base, Mars base, lunar base. The materials used in this model are applicable for the purification of 1 litre water. We have used this model four times & every time we have got the same quality of water. The maximum duration of the working capacity of this model is 25 days . This model has been prepared on the basis of the quality of the water we have used. After making this model, a maximum quantity of 75 litres of water can be used. If the amount of water taken for purification exceeds 1litre,the materials used in the model must be increased as per the requirement. This water sample was collected from a nearby pond of a factory. 20

  21. Cost analysis • Materials / Apparatus ---- 200/- • Holder------50/- • Chemicals------ 150/- • Contingency------50/- • Video editing & Camera----1100/- Total ----- Rs. 1550/- 21

  22. Our future plan We want to recycle the human urine and remove ammonium part from human urine. And also we want to make a healthy society. We hope everybody can get pure water for drinking. 22

  23. Conclusion Before our experiments Result from the working model Chemicals Quantity Chemicals Quantity Turbidity (NTU) 24.0 Turbidity (NTU) 9.8 pH Value 10.26 pH Value 6.1 Iron (mg/lt) 5.84 0.11 Iron (mg/lt) Fluoride (mg/lt) 0.51 Fluoride (mg/lt) 0.12 Hardness (mg/lt) 220.0 Hardness (mg/lt) 20.0 Chloride (mg/lt) 75.0 Chloride (mg/lt) 4.0 23

  24. Conclusion pH value—6.1(acceptable) Iron (mg/lt)---0.11(acceptable) By designing the Working model we could get access chemicals free the water. 24

  25. Acknowledgements • THIS PROJECT IS THE FRUIT OF THE LABOUR OF MORE THAN A SINGLE PERSON. WE STILL BEING LEARNERS, WOULD HAVE BEEN DIRECTIONLESS WITHOUT THE GUIDANCE, ADVICE AND CO-OPERATION OF THE PEOPLE WHOSE NAMES ARE CITED BELOW. WE EXTEND OUR HEARTIEST GRATEFULNESS FOR THEIR IMMENSE CONTRIBUTION. 25
