Optimizing the Performance of Solar-Pond-Coupled Solar Stills via Taguchi Methodology

Abstract:

This study investigates the enhancement of solar still efficiency through the integration of a mini solar pond and reflective mirrors. Key variables affecting performance were identified: sodium chloride concentration, solar pond zone, and mirror angles. Four parameters were systematically varied across three levels and analyzed using an orthogonal array (L27). ​The optimal configuration was determined through Signal-to-Noise (S/N) ratio analysis, revealing that a concentration of 2.5 kg sodium chloride, a 75 cm solar pond zone, and specific mirror angles significantly improved distilled output. ​ It endeavors to uncover the significant factors contributing to the enhanced efficiency of the hybrid solar still-solar pond system and to establish the ideal configuration of parameters that improves distilled water generation capacity. Experimental results showcased a maximum daily water production of 3.25 liters with an efficiency of 53.26%. The research provides valuable insights for optimizing solar still performance in real-world applications, laying the groundwork for future advancements in solar desalination technologies.
