“…Al-Karaghouli also investigated the influence of insulation thickness on single and double basin stills and found the efficiency to be increased by 2-4% when side of the basin is insulated (Al-Karaghouli and Alnaser 2004). Al-Hinai et al (2002) have shown that optimum insulation thickness should be of 0.09-0.13 m. Therefore, insulation thickness of 0.10 m can be used in 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.

“…The higher the temperature, the higher the yield. Al-Hinai et al (2002) have shown that increasing ambient temperature of 10 °C will increase the yield up to 8.2%. Thus, the still should be placed where there is no shadow and has a high ambient temperature.…”

“…Akash et al (1998) and Tiwari and Tiwari (2007) were carried out to determine the still efficiency, the efficiency was ranged from 15-25%. Moreover, a parameter study was performed Al-Hinai et al (2002) on a conventional double-sloped single basin solar still under climate conditions of the sultanate of Oman at the Gulf region, this study showed that under optimum design condition, the still trends to give an Science Publications AJEAS average annual solar yield of approximately 4 l/m 2 day. Nafey et al (2000) stated that using black gravel of 20-30 mm size improve the productivity by 19% at the condition of 20 l/m 2 brine volume and 15 glass cover angle.…”

The basin solar still was developed by adding a magnetic treatment unit, it's energy 0.12 Tesla and two layer of glass provided with water between them. The study was conducted by testing the device by using magnetic water + double glass provided with water, non magnetic water + double glass cover, magnetic water + single glass cover, non magnetic water + single glass cover and control treatment (without additions). Intensity of incidence solar radiation in Basrah province during the month of April, Temperature in the basin solar still, glass cover surface, ambient, pH, water electric conductivity, productivity, density, physical and chemical properties were measured. Theoretical productivity and efficiency were calculated. The results showed that the average of solar radiation intensity is 889.55 W/m 2 . Temperature of basin solar still, glass cover surface and ambient was increased with increasing solar radiation intensity. The maximum of temperature in the basin water of solar still is 56.61°C at using magnetic water + single glass cover which has best performance compare with other treatments and having pH 7.03, minimum electric conductivity is 0.000672 S/m and density reached to 1000 kg/m 3 and gave highest efficiency at 32.55% and it's productivity improved by 50% compared with conventional.
