Abstract
Drinking water, the basic requirement for life is deteriorating day by day and its sources are decreasing at a faster rate. Sea water is present in abundance on the Earth but converting it to drinkable form is expensive for domestic usage. The paper focuses on purifying the sea water using the humidification and dehumidification process and reducing its TDS so that it can be consumed. The system works on the principle of the natural water cycle in which the sea water evaporates and humidifies the air just above. As the temperature of air drops below its dew point, the vapour in the air condenses and falls on the earth as rain. Similarly, the experimental setup consists of a solar water heater of evacuated tube collector to heat the water, a double-pipe heat exchanger to heat the impure sea water from hot water, a humidifier where the air gets heated and humidified by the impure water, and a dehumidifier where the air gets cooled below the dew point and thus its condensation results in pure water. The paper presents the design of a humidifier, dehumidifier, and double-pipe heat exchanger and the results obtained from the setup built based on the design.
