Design methodology for a salt gradient solar pond coupled with an evaporation pond

The arid conditions in northern Chile restrict the access to water and energy and the development for small mining entrepreneurs. For this purpose, this work describes the experimental behavior of a novel sustainable solar water heating system that is suitable for open ponds combined with floating covers and photovoltaic cells which supply the required energy for water pumping and measurement accessories. The heating is provided through solar panels and coil heat exchanger;

“…The 'dynamic stability' and 'equilibrium boundary criterion' discussed and confirmed experimentally for the lower and upper gradient interfaces. A salt gradient solar pond coupled with evaporation pond was studied by Agha et al [29,30]. They established that salt reconcentration due to evaporation had occurred to be an effective method of providing salt to the main solar ponds.…”

Water and energy are the most important topics on the environment and sustainable energy development agenda. The social and economic health of the modern world depends on sustainable supply of both energy and water. Many areas worldwide suffering from fresh water shortage are becoming increasingly dependent on purification as a highly reliable and non-conventional source of fresh water. Therefore, purification market has greatly expanded in recent decades and expected to continue in the coming years. The integration of renewable energy resources in purification and water purification has become increasingly attractive. This is justified by the fact that areas of fresh water shortages have plenty of solar energy and these technologies can be used due to their low operating and maintenance costs. This review paper discusses the systems that can be used to harness renewable energy sources including, solar collectors, solar ponds, photovoltaics, wind energy and geothermal energy and finally a discussion and conclusion about some distinguished features of each process. Merging of these renewable energy sources with conventional sources has led to optimize the performance of purification plant, less maintenance requirement and reduction in overall cost. It was found that, to choose the best renewable energy source for a purification plant in a particular area, important determinative factors should be considered such as water salinity, area remoteness, plant size, technical infrastructure of the plant, capacity factor, energy consumption and capital cost of the equipment.

“…The paper also presents the difficulties faced by the operating team, actions and majors that have been taken to overcome them. Agha et al [9], presented the results of a simple mathematical model for predicting the ratio of the Evaporation Pond (EP) area to that of a SGSP area. The EP idea provides a very attractive method of salt recycling by evaporation, especially in areas of high evaporation and low rates of rain as it is the case for North Africa.…”

Solar and renewable energies applications got great interest and attention in the last few decades. Problems related to CO2 emissions, air pollution, Ozone layer depletion, global warming, and environmental issues raise the necessity for getting clean and safe energy. For this purpose, the Center for Solar Energy Studies (CSERS) in Libya conducted huge research work in different applications for solar and renewable energies. One of these important activities is the Solar Gradient Solar Pond technology. It is an effective solar energy collection and storage system which presents a relatively simple and economic method of providinglow-grade energy with the advantage of an annual storage cycle.This paper presents a general review of researches and studies on solar ponds that were conducted by the CSERS research team. Tajoura’s Experimental Solar Pond (TESP) is designed as an experimental facility enabling the investigation of various aspects of pond performance. It is constructed by the Center for Solar Energy Studies, in joint cooperation with a Swiss company, with a surface area of about 830 m2, and a depth of 2.5 m, coupled with an evaporative pond of 105 m2 area and 1.5 m deep, equipped with all necessary equipment and measuring control system.The paper also shows the experience of operating MSF desalination unit coupled with TESP solar pond. Finally, other factors affecting the solar pond’s thermal stability were also discussed.
