Development of Seawater Distiller that Uses Electrical Energy for Sustainable Clean Water Production

Riyanto Haribowo, Emma Yuliani, Andi Gora Prasetyo

 

Abstract: This study aims to
develop a seawater distiller that can be used to purify water by using
electrical energy to power the heating elements used in the condensation phase
of distillation. Varying numbers of water heating elements and water levels in
the evaporator unit were analyzed to determine the ideal device configuration.
The distillation device consisted of a container unit, a water level control
unit, and an evaporation chamber unit. Distillation was conducted in two
experiments, one with a water level of 8 cm and the other, 4 cm, in the
evaporation unit. Each experiment comprised eight tests, in which 1–6 water
heating elements were used in various configurations; identical configurations
were used in both experiments. The seawater used was obtained from the Indian
Ocean off Balekambang Beach, Malang Regency, Indonesia. The largest purified
water volume obtained among the 16 experimental conditions was 3.94 L at a cost
of IDR 790 per liter. The effectiveness percentage toward water quality
improvement in terms of pH, electrical conductivity, TDS, and maximum salinity
was 9.88%, 99.98%, 99.96%, and 100%, respectively. In the future, a full-scale
experiment will be conducted on site. The use of this device will therefore
benefit people in areas with water scarcity.
