“…Different designs of single and double slope single basin passive solar stills with glass cover and black painted basin were constructed and tested experimentally in several countries with different climate conditions such as Saudi Arabia [10], India [11], Egypt [12], Cote D Ivoire (Ivory Coast) [13], and Malaysia [14] and each had a different cumulative productivity of 2.5, 1.88, 3.58, 4.10, and 2.26 kg/m 2 .d, respectively. The performance of those solar stills was investigated for durations of 1 day, 5 days, 3 days, 1 day, 4 days, 1 day, and 5 days in Saudi Arabia [10], Malaysia [4,6], India [11], Egypt [12], Cote D Ivoire (Ivory Coast) [13], and Malaysia [14], respectively. According to the World Health Organization (WHO), a person needs 2-3 L potable water per day for survival [15].…”

Solar stills are very cost-effective technologies used in producing potable water. This work aims to investigate the productivity of two passive double sloped solar stills fabricated with different cover materials with similar shapes; polythene film (PSS) and glass (GSS). The first solar still was made of a transparent polythene film, PVC pipes and a black painted stainless steel trough as cover, frame and basin, respectively. The second one was fabricated using glass as cover, with similar basin material. Experimental outputs indicated that GSS had 1%-5% higher yield than PSS throughout the experiment. The fabrication cost of PSS was 5 times less than the cost of the GSS. The thermal energy efficiencies of PSS and GSS were obtained as 34.05% and 35.50%, respectively. A mathematical model for each solar still was developed using the relationships of heat and mass transfer and their calculated and experimental productivities were in good agreement. Water quality parameters tested showed that water produced from both solar stills met the WHO standards for drinking purposes.

“…Velmurugan et al (2008) have done a performance analysis for productivity enhancement of stepped solar still, and they increased the output by 98%. Kabeel et al (2012) experimented stepped solar still with varying water depth of trays and width, and they found that at 5 mm water depth and 120 mm width of the trays the yield is maximum which is 53.7% higher than conventional still. So 4-5 mm water depth and 100-120 mm tray width should be used for the proposed still.…”

Pure and fresh water is being scarce day by day. Although Bangladesh is a riverine country, pure drinking potable water is not a cheap commodity. Most of the people in the cities boil water to drink, and people of the villages take tube-well's water directly, which might have high amount of heavy metal like arsenic. Solar still is a cheap and very useful renewable technology, which can be used in Bangladesh extensively everywhere at the rooftop as a pure water source. Objective of this paper was to find a low cost portable and easily maintainable passive solar still for southern part of Bangladesh. All the parameters of passive solar still are studied, and it is found that an inclined stepped solar still with passive condenser, internal and external reflectors, black cotton wick, and with optimum design values can be the desired still, which would give maximum yield. Finally, the optimum values of the parameters are used to propose a cheap design.
