“…An error analysis was performed to check the impact of errors in the experimental observations on the techno-economic analysis and conclusions. The uncertainty of measurements (Table 3) was calculated based on the formulae given below, as proposed by Sandeep et al, (2015), Alaudeen et al, (2014), Kumar and Tiwari, (1996) and Velmurugan et al, (2008a), in which U i corresponds to internal uncertainty, corresponds to the average X of experimental observations of productivity in each set, X i corresponds to the average of averages of experimental observations in each set, N is the total number of experimental observations and N o is the number of observation in each set.…”

This paper investigates the effects of nanoparticle-enhanced phase change material (NPCM) on solar still operation and performance. Technical and economic aspects were considered, to show an advance on earlier works using virgin phase-change materials (PCM). Three types of nanoparticle (TiO 2 , CuO and GO) were impregnated individually at 0.3 weight% in paraffin to form NPCM-1, NPCM-2 and NPCM-3 respectively. Experiments were conducted with four solar stills (SS) each of 0.5 m 2 area using respectively paraffin (SSPCM), paraffin-TiO 2 (SSNPCM-1), paraffin-CuO (SSNPCM-2) and paraffin-GO (SSNPCM-3). There was observed an increase in thermal conductivity and a reduction in melting and solidification temperatures, with NPCM compared to PCM. The effects of NPCM on water temperature, storage temperature, hourly and annual productivity were determined. SSPCM, SSNPCM-1, SSNPCM-2 and SSNPCM-3 yielded 3.92, 4.94, 5.28 and 3.66 l/m 2 /day respectively, corresponding to 26 and 35% increases in productivity of SSNPCM-1 and 2 respectively over SSPCM. Economic analysis showed cost per liter

IntroductionGreater growth of population and industries results in shortage of fresh water. Earth is almost covered with a larger water source and smaller land mass. People used to drink large amount of water for their thirsty need. Water available in the form of rivers, lakes cannot be consumed directly without pre-processing, as these need some purification process in order to remove bacteria and undissolved salts. In early days the possible method of getting pure water is heating the brackish water and condensing them back to get fresh water by burning fossil fuels. Due to the exhaustion of coal, crude oil and increases in global warming, the evolution of using renewable energy for getting fresh water evolved during the late 20th century. One of the best energy source applied is solar energy. Source of energy from sun is mostly environmental friendly and non polluting clean energy source. Basin type still is the most aged process of producing fresh water [1][2][3][4][5][6][7][8][9][10]. The fresh water conversion rate from the solar still system is predominantly depends on the solar intensity. The basin water temperature increases continuously due to heat energy emitted from the sun in the form of solar intensity. After reaching the boiling point of water, the water evaporates and it condenses on the solar still condenser cover. The various techniques employed in solar still, to raise the temperature of water and hence increases the productivity was studied from the detailed literatures reviews of Ravishankar et al. [11], Kabeel et al. [12] and Manokar et al. [13][14][15]. From the detailed literature studies it is clear that water temperature can be improved by either feeding waste warm water or pre heat the water by incorporating the different solar collectors or concentrators. Gupta et al. [16] theoretically analyzed the intermittent flow of waste warm water to the double basin solar still similarly same analyses was done by Yadav et al. in single basin solar still [17]. Sodha et al. [18] and Tiwari et al. [19] experimentally investigated the performance of solar still utilizing the warm water from the industry. Tiwari et al. [20] keep up a higher temperature difference between the water and collector cover by increasing the water temperature by flowing waste hot water in the basin and decrease the collector cover temperature by flowing the cold water above the surface of collector cover. This would results in increase in both evaporation and condensation

Passive solar stills are used for solar distillation. But the yield of passive still is very low, and often fails to meet the demand. Water is one of the fundamental sources for the survival of mankind on the globe. As world having just a little measure of water assets for utilization purpose, individuals living in undeveloped countries and urban zones are getting affected by consuming dirty water that prompts water‐borne illness. Despite the fact that groundwater is accessible in little amount, it must be suitably treated before its utilization for domestic use. Salty water contains dissolved and undissolved substance, and henceforth, it is not advisable for family drinking purpose. To enhance the productivity of fresh water, several techniques were employed. Furthermore, increase in yield of fresh water depends on various environmental parameters and rate of condensation. In this article, a complete review of various methods employed to enhance the condensation rate on an active solar still has been presented. Solar still incorporated with the evacuated tube collectors (ETC) and thermo electric modules (TEM) increased the still effectiveness up to 68%. © 2018 American Institute of Chemical Engineers Environ Prog, 38: 286–296, 2019
