Revolutionizing Water Purification: Advanced Membrane Technologies for Enhanced Solar Distillation

This study explores the development and performance evaluation of modified double-slope solar still (MDSS) configurations using recyclable materials. The objectives include improving water yield, thermal efficiency, and cost-effectiveness. Experimental data were collected hourly under typical climatic conditions, focusing on parameters such as material type and operational modes. Results indicate significant improvements in water productivity, with the MDSS-Al-S700 achieving a daily yield of 7,527 mL.m- ² and a thermal efficiency of 45.7%. The cost per liter was reduced to ₹0.014, demonstrating remarkable economic viability. The findings highlight MDSS systems as sustainable and scalable solutions for addressing water scarcity, with enhanced environmental payback times and reduced carbon emissions. These advancements underline the potential of MDSS systems to align with global sustainability goals while ensuring affordability and efficiency.
