“…In the other handthe magnetic water led to increasing of evaporation. These results agreed with Samee et al (2007), who stated that higher values of conductivity indicate presence of more dissolved solids and hence more salinity. The acceptable range of pH for drinking water is between 6.5 to 8.5. pH measures water acidity or alkalinity.…”

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.

“…The technology desalinates brackish water or seawater either using solar distillation or an indirect method whilst converting the solar energy into heat or electricity [39][40][41]. It is an environmentally advantageous and cost-effective technology; hence, it is much patronized by communities in rural regions [41].…”

“…Most of the regions in the country have brackish subsoil water which is not appropriate for human and other living inhabitants [33]; hence, desalination by means of solar energy will be beneficial and sustainable in providing portable water for the rural areas of Sindh, Baluchistan, and Punjab [41] The government of Balochistan has installed two solar plants in Gawadar, comprising 240 stills and each plant has the capacity to treat up to 6000 g day −1 of sea water. Projects to develop the same solar plant system have been initiated in different areas of Balochistan and other province of Pakistan [41]. The Pakistan Institute of Engineering and Applied Sciences (PIEAS) has fabricated a single basin solar still with an optimized efficiency of 30.62 %, being comparable to stills used globally.…”

Renewable energy deployment to combat energy crisis in Pakistan

The huge deficiency of electricity due to heavy reliance on imported fuels has become a significant impediment to socio-economic development in Pakistan. This scenario creates an increase in local fuel prices and limits potentials in the establishment of new industrial zones. The current gap between the demand and production of electricity in Pakistan is approximately 5000-8000 MW with a constant increase of 6-8 % per annum. Hence, more sustainable and renewable energy sources are required to overcome the existing problem. Pakistan is endowed with potential renewable energy resources such as wind, solar, hydro, and biomass. These resources have the capacity to be major contributors to future energy production matrix, climate change reduction efforts, and the sustainable energy development of the country. This article reviews the availability of alternative energy resources in Pakistan and associated potentials for full-scale development of sustainable energy systems. It also discusses exploitation strategies to increase the distribution of indigenous energy resources.

“…Considering the glass cover as a volume control, as shown in Figure 3, the energy balance equation of the glass cover is expressed as: (12) where h f ,v is the enthalpy of the saturated water at T v , and τ g is the transmittance of the glass cover for visible light (τ g = 0.824). It should be noted that heat losses from the front and back borders of the glass are very low, which can be neglected for calculations.…”

“…A large number of studies have been dedicated to experimental or theoretical analysis of the basin solar still. For example, Samee et al [12] designed a simple single basin solar still with a base area of 0.54 m 2 and glass cover inclined at 33.3 • for Pakistan. The average daily output and efficiency of the solar still were found to be 3.15 L/day·m 2 and 30.65%, respectively.…”

Abstract:In this study, a thermal model for estimating the efficiency of a basin solar still with an external reflector was introduced using the energy balance equations of different parts of the solar still. Then, in order to verify the precision and accuracy of this model, a basin solar still with an external reflector was constructed and some experiments were performed. The hourly temperature values for different places of the still and amount of distilled water were calculated using the thermal model and compared with experimental measurements. Comparisons show that the thermal model of the still is in good agreement with the experimental results. Therefore, it can be concluded that the introduced thermal model can be used reliably to estimate the amount of distilled water and efficiency of the basin solar still with an external reflector. Results also revealed that the efficiency of the solar still is low in the early hours, while it was enhanced 44% in the afternoon. Furthermore, it was concluded that the accumulated distilled water is 4600 mL/day and 4300 mL/day for theoretical and experimental examinations, respectively.
