The performance of one solar pond as a passive step in distilled and potable water production from desalination effluent is surveyed in this research. This solar pond is proposed in a zero discharge desalination process to prevent the salinity shocking which is made by a brackish water stream that exists from desalination units. The solar pond performance is evaluated by measuring three types of efficiency, experimentally, and mathematically. The efficiencies which are defined and calculated from experimental data are conductivity efficiency, thermal efficiency, and water recovery efficiency. The mathematical results are verified by experimental data which has been obtained during a year. The theoretical modelings show very good agreement with experimental data, especially for water collection and conductivity efficiency evaluation. The relative error of theoretical and experimental results for thermal efficiency evaluation through the day and night is obtained 7.2% and 4.9%, respectively.

Experimental evaluation of double slope solar still integrated with parabolic trough collector having 28.1% higher productivity over the conventional solar still have been reported by Fathy et al [1]. N identical evacuated tubular collectors integrated double slope solar still and its performance on the basis of exergy based energy payback time, duration, life cycle conversion and production factor have been reported by Singh and Al-Helal [2].…”

Experimental and theoretical analysis of the three single basin double slope solar stills with 15˚, 30˚ and 45˚ glass cover inclinations, are carried out at meteorological conditions of Raghogarh, Guna (Latitude: 24°39'N, Longitude: 77°19'E, India). The experiments are performed from 14th to 16th June 2017. Detailed energy and exergy analysis are carried out using theoretical model proposed by Kumar & Tiwari, based on regression analysis. It has been observed that the theoretical results obtained from evaluation have good agreement with the experimental results. Maximum fresh water is obtained from 15˚ inclined glass cover solar still (viz.4.66 litre of 14 h observation) and contribution of 52% and 48% from east and west side of solar still respectively. At 15:00 h all the stills show maximum thermal efficiency viz. 23.69, 29.24 and 25.09% for 15˚, 30˚ and 45˚ cover inclinations respectively. It has been observed that maximum exergy is lost in basin followed by glass and water in all the double slope solar stills.

“…The use of silicone rubber has enhanced saline water evaporation efficiency [9]. The results have shown that a solar still coupled with parabolic trough collector (PTC) is more competent than a conventional solar still [10]. Attaching fins to the adsorbent plate increases the evaporation rate and solar still efficiency [11].…”

The present study mainly focuses on enhancing the performance of solar still unit using solar energy through cylindrical parabolic collector and solar panels. A 300 W solar panel is used to heat saline water by thermal elements outside the solar still unit. Solar panels are cooled during the hot hours of the day; thus, reducing their temperature may lead to an increase in solar panel efficiency followed by an increase in the efficiency of the solar still unit. The maximum amount of freshwater used in the experiment was 2.132 kg/day. The experiments were modelled using ANNs. Based on neural network simulation results, there is a significant correlation between experimental data and neural network modelling. This paper compares experimental data with data obtained from mathematical modelling and ANNs. As a conclusion, the artificial neural network prediction has been more accurate than the simplified first principles model presented.
