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.

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.

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.

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.

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