“…Garg and Mann (1976) experimented that output of a still decreases with increase in depth of water level in the still. Phadatare and Verma (2007) also got the similar result when they experimented with plastic solar stills with different water depths. Tiwari and Tiwari (2007) found that lower water depth such as 0.02-0.04 m has higher annual efficiency up to 44% compared to higher water depth such as 0.18 m. So the proposed still would have minimal water depth.…”

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.

“…However, the PSS had lower fabrication cost of RM 82.05 compared to GSS fabrication cost of RM 416.00. In this study, GSS and PSS yielded a higher water production compared to the passive solar stills previously investigated in Malaysia [4,14,40,41], India [8,11], Italy [9], Jordan [42], Saudi Arabia [10], and Turkey [43]. The relationships between calculated (M cn ) and experimental (M cexp ) cumulative water production of GSS and PSS are shown in Figures S8 and S9 (Supporting Information), respectively.…”

“…It was observed that the solar still with the least water depth of 1.5 cm had the highest daily output of 1.55 kg/m 2 . Phadatare and Verma [8] performed an experiment with a single basin single slope plastic passive solar still using Plexiglas as its fabricated frame and cover materials. The influence of water depth in basin, from 2 cm to 12 cm, was investigated using this solar still.…”

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.

“…So, most of the water filled systems show high distillate yield after noon. Phadatare and Verma [3] have studied the variation of productivity with respect to water depth and have concluded that productivity decreases with an increase of water depth. Kalidasa Murugavel and Srithar [4] have conducted experiments on basin-type solar still with different wick materials and concluded optimized output using light cotton wick.…”

Thermal aspect of solar energy is widely used in the desalination plants. Experimental investigation and mathematical modeling of inverted V-type solar still integrated with drip system are presented in this paper. The experiment is performed in the Kerala climatic conditions (10.8439 ∘ N, 76.0328 ∘ E), March 2012 at M E S College of Engineering, Kuttippuram. A two segment still of 2 m 2 is constructed. Experimental investigations on productivity and internal heat transfer are analyzed. The results indicate that the mean standard deviations between theoretical and experimental values are less than 7% (temperature of rippled wick), 8% (temperature of glass in rippled system), 11% (temperature of flat wick), and 7% (temperature of glass in flat system), an average for the working hours of the day.
