“…The graphs also justify that the temperature difference (that is, the difference between the glass cover and absorber plate temperatures) is the major factor responsible for evaporation. This trend was also observed by several authors (Ahsan et al, 2013;Ali et al, 2019;Edeoja et al, 2015;Kumar and Bai, 2008;Murugavel et al, 2010;Onyegegbu, 1986;Ozuomba et al, 2017;Sathyamurthy et al, 2015). Preheating the feed water to the solar still basin plays an important role in increasing the productivity of the still (Ahmadi et al, 2017;Badran and Abu-khader, 2007;Delgado-Torres et al, 2007;Kalogirou et al, 2016).…”

Abstract. The enormous problems caused by the scarcity of potable water and the transmission of waterborne diseases such as cholera, dracunculiasis, hepatitis, typhoid and filariasis in some parts of Nigeria have created a public health concern. Every day thousands of lives are lost due to contact with waterborne diseases. The insufficient medical resources available in developing countries are deployed towards the treatment of waterborne diseases that can easily be avoided if potable water can be made available. This study seeks to investigate the purification of four different water samples (namely water from flowing rivers, freshly dug well or groundwater, rainwater from the rooftops and heavily polluted dirty water) consumed by the people in the local community using a solar desalination method. A single basin solar still was constructed, and experimental studies were carried out to determine the influence of solar insolation and temperature variations on the yield of the distillate for both the passive and active solar stills tested. The quality of the distillate was tested by measuring the total dissolved solid (TDS) and electrical conductivity (EC) and later comparing it to the World Health Organization (WHO) standard for drinkable water. The values obtained after desalination fall within the acceptable/tolerable range for TDS and EC, in accordance with the WHO standard for drinkable water. This analysis provides an indigenous distillation method to enhance the production of drinkable water at a low cost.

“…The paper [6] was carried out to analyze the temperature difference between the inner and outer glass covers of conventional basin type solar stills and low thermal inertia solar stills obtained by modifying conventional stills, and it was found that for conventional stills, the maximum temperature difference was up to 7.14 % during the day and significant in the morning and evening, then for low thermal inertia, the difference is greater up to 10.2 %. Then in the paper [7] which was a study that used a tilt type solar-powered water distillation tool, this distillation tool was analyzed so that it was found that the tool could produce an average of 0.09 m 3 of water per day.…”

Water is a very important component for humans in everyday life. The need for clean water is currently increasing, especially for people living in coastal areas, this is because the water still contains salt and smells. Solar radiation energy is an alternative energy source. However, its use has not been utilized optimally, as science develops, solar energy has become an object of research, and one discovery of the use of solar energy is distilling sea water using solar energy. Under these conditions, research will be carried out on clean water distillation equipment, to see and analyze the productivity of water produced by clean water distillation equipment that uses zinc-coated steel tanks. The results obtained do not rule out the possibility that this distillation device with a zinc-coated steel tub can be used to reduce the problem of lack of clean water, especially as it is known in coastal areas where solar energy sources are not only abundant but also very abundant, but the availability of clean water is limited. still very minimal. So that existing solar energy sources can be used as an energy source in distillation equipment to produce clean water. From these results, the productivity of the water produced can be seen that solar radiation has a great influence on increasing the efficiency of the distillation equipment. Then the results of condensate water production and efficiency produced by a tool with a one-sided cover glass are greater than a tool with a double-sided cover glass

The performance of a double effect solar distillation unit incorporating a paraffin wax has been studied experimentally under the climatic conditions of Owerri, South-East Nigeria. The system comprises double basins with an absorber area of 1.10m 2 and a saline water storage tank. It was positioned in the North-South direction with both upper and lower glazings inclined at the latitude of the study location. Performance evaluation of the system was conducted for an extended period of time, capturing both diurnal and nocturnal phases of the system's operation. The hourly distillate yields of the upper and lower basins were compared. The lower basin performed better than the upper basin during diurnal phase. The diurnal distillate yield of the system ranged from 0.415L to 0.741L for the lower basin and zero to 0.025L for the upper basin. The system achieved a maximum distillate yield rate of 0.21 L/h and an average efficiency of 11.71%.
