Experimental Analysis of Potable Water Generation using Humidified Air

Abstract

Overcoming the problem of water scarcity is the need of hour. Although desalination process and other sustainable methods are in pipeline for overcoming this problem still, they are in a budding stage as of now. Hence an alternate solution in overcoming this problem is the utilization of atmospheric dew water. Atmospheric dew water has humongous potential in developing the potable water. This source still remains untapped to a large extent. Hence, in this work it is aimed at extracting potable water by utilising the atmospheric dew water. An experimental set up was made consisting of the compressor, condenser, expansion valve and evaporator through which water is collected. This water is collected on daily basis for a period of 7-month tenure and the yield and purity of water is examined experimentally. The monthly average water yield on a daily basis is calculated and the cost analysis for the generation of per litre of water is performed. The outcomes of this work showed the water generation of 20 litres a day on average and the average cost for its generation for a litre was calculated to be INR 14.12 /- which is less than a dollar. At humidified geographical locations this method proves to be a consistent and sustainable solution to overcome the gigantic problem of water scarcity.
