“…Additionally, solar energy is a free and sustainable source of power, eliminating the need for fuel costs. The only drawback of solar energy is that it requires more space for the collection of sunlight (Sebaey, 2013). Nonetheless, this method remains a great alternative for obtaining fresh water from hard water sources in the country.…”

Solar energy is abundant in Sri Lanka, but there is currently no efficient method to use solar energy to purify polluted water into fresh water. This study aimed to address this issue by introducing an advanced solar water distillation system. The basin size of the prototype unit was 0.48 m2 and its performance was tested using different setups: a basin only (T1), a basin with a flat-plate solar collector (T2), a basin on a sand layer (T3), a basin with sponge cubes (T4), and a basin with all components together (T5). Data were collected at 30-minute intervals from 6.00 am to 6.00 pm for each treatment. The results showed that T5 performed significantly better than the other treatments (p<0.05). The maximum temperature recorded for the basin water was 59°C when the ambient air was at 64°C in T5. The flat-plate solar collector, sand layer, and sponge cubes contributed to increase the distilled volume by 73.0%, 20.5%, and 48.2% respectively. The new solar water distillation system with all the features (T5) can improve the distillation productivity by 138% compared to the conventional type (T1) by giving 4143 ml/m2/day of average production. The new distillation system is an effective solution for addressing the drinking water issue in agricultural areas, as it consistently demonstrates satisfactory quality in terms of pH, EC, TDS, and concentrations of As and Cd.

Water is a vital component of human survival. Drinking water is scarce in several large provinces around the world. Only saline water, which may be demineralised and utilised for drinking, is available in this situation. For extended journeys, normal water is required in boats and submarines. Self–demineralised equipment is usually installed in vehicles, but it consumes more conventional gasoline and is, therefore, more expensive. To address this problem, solar still can be used, which has the primary aim of converting seawater into consumable desalinated water. In this work, a solar still with phase change material (PCM) – RT58 which have better thermo-physical properties has been incorporated and investigated for thermo-economic performance. It is observed from the results that the RT-58 PCM achieved a greater yield compared to conventional solar still (CSS) without any PCM as an energy storage material. The productivity of solar still with PCM is increased by 46% relative to CSS. Also, the economic analysis revealed that the solar still with PCM is more economically viable than CSS in terms of cost per litre production of freshwater and payback period.
