Abstract
The impact of adsorbent media on freshwater productivity and desalination efficiency in solar-powered interfacial desalination systems and terraced ponds is methodically assessed in this work. This experiment used four basins of the same size, but with different absorbent media: Ceiba pentandra charcoal, Gliricidia sepium, Schleicera oleosa, and a control without absorbent media. In addition to analyzing desalination volume and efficiency, the Surface Area Analyzer (SAA) was also tested. The test results showed that, overall, Gliricidia sepium wood charcoal produced a high water volume of 120 mL/h and a desalination efficiency of 21.96%. This happens because Gliricidia sepium charcoal has the highest surface area, pore volume, and pore distribution. Compared with previous reviews that focus on energy requirements, energy savings, and high efficiency in complex pond construction, this paper proposes a simple construction pond that utilizes solar energy, thereby achieving greater efficiency, maximizing desalination volume, and improving the sustainability of the energy-water-environment relationship.
