Remarks of the poor quality waterThe 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. 9Group meetingWater sample

About our modelThis 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

Cost analysisMaterials / Apparatus ---- 200/-Holder------50/-Chemicals------ 150/-Contingency------50/-Video editing & Camera----1100/-Total ----- Rs. 1550/-

Our future planWe 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
