Techniques for improving the productivity of a single slope solar still distillation of fresh water: A review paper.

Numerous human activities and a rapidly growing world population are increasing the demand for freshwater. Fresh water production relies heavily on the use of conventional fuels and is associated with environmental pollution, leading to the need to look for other alternatives such as clean energy (solar energy). There are many villages and rural areas in the world without access to clean water. Many desalination systems have been developed to address this shortcoming. This study describes strategies for increasing clean water solar energy productivity that are currently in commercial and experimental development stages. Solar stills are the most prudent method for delivering new water since they just sudden spike in demand for the energy of the sun, which is promptly accessible in nature. The focus is on technologies that can be used independently, especially those that can be integrated into solar thermal systems. The results show that the solar thermal distillation yield is inversely proportional to the basin water depth and is directly related to the wind speed in the absorbing region, the temperature of the glass covers and the incident solar radiation. Add to the technology used inside and outside the system to improve productivity. [ABSTRACT FROM AUTHOR]
