Cords wick distillers for water distillation - A comparative review

This review examines advancements in cords wick technology for optimizing water depth in solar stills, a crucial factor in enhancing desalination efficiency. Shallow water depths generally lead to increased productivity, and cords wick technology effectively reduces energy waste by drawing only evaporated saline water, minimizing hot water loss. Various modifications, such as reflectors, fans, and baffles combined with nano-enhanced PCM, have significantly improved the performance of cords wick solar stills. Notably, incorporating cords, reflectors, a fan, and square baffles resulted in a 264 % increase in distillate production. Additionally, these enhancements offer environmental benefits, with reported annual CO₂ emissions reductions of approximately 28.71 tons and water treatment costs ranging from $0.01 to $0.0185 per liter. The insights provided here contribute to the ongoing research on maximizing desalination efficiency using cords wick technology in solar stills.
