The present study aims to develop an innovative hybrid system powered by solar energy to dry plants and produce pure water, suitable for remote regions that suffer from power problems and the problem of lack of pure drinking water. This was done by integrating a two-stage dryer unit with modified solar still with an air injection system and external condenser to dry plants as well as produce pure water. The integration of the modified solar still and external condenser with the two-stage dryer unit aims to increase the rates of pure water productivity, by injecting the hot humid air that leaves the drying unit into the modified solar still. The performance of the developed and innovative hybrid system was studied theoretically, and the mathematical models were validated using the previously published experimental results. The results presented that, the suggested two stages of the dryer with reheating represent an excellent design that improved the mass of water that was removed from the products by 72.65% as compared to only the first stage of the dryer unit. The proposed innovative developed hybrid system can be produced cumulative pure water with a rate reaching 49.94 liter/day, with an improvement of 592.65% as compared to only modified solar still with air injection. Also, the proposed innovative developed hybrid system represents a good choice which improved the gain output ratio by 177.93% on average as compared to only a two-stage dryer unit with reheating.

The present study aims to innovate small hybrid desalination plants suitable for remote regions working with higher productivity and lower cost of the produced fresh water. To achieve this idea, the small RO desalination plant was combined with the solar still, as well as this innovative hybrid desalination system was combined with the photovoltaic/thermal panel and the evacuated tube solar collector as preheating units to heat the water before it entered the proposed innovative small hybrid desalination plant. To illustrate the characterized of the proposed innovative small hybrid desalination plant, the performance of an innovative small hybrid desalination plant was compared to the conventional small RO desalination plant experimentally under the climate conditions of Tanta city, Egypt. The results presented that the annual permeate water that can be produced from the conventional small RO desalination plant without modification reached 173.74 m3/year, but for the proposed innovative small hybrid desalination plant the annual permeate water that can be produced will be increased to 352.59 m3/year, with an improvement of 102.94%. Also, the economic analysis presented that the cost of permeate water produced from the conventional RO plant without modification reached 0.915 $/m3. But the permeate water cost produced from an innovative small hybrid desalination plant will be reduced to 0.8178 $/m3, saving 10.62%.

This manuscript aims to augment the production rate of drink water from the hemispherical solar distillers using red bricks filled with cement as natural low-cost reasonable storage materials. To obtain the optimal height and optimal gap distance of the red brick tiles filled with cement that achieves the highest productivity of hemispherical distillers. Three different heights of the red brick (1, 2, and 3 cm) with two different gap distances of (4 and 6 cm) were experimentally studied. Therefore, three hemispherical distillers were constructed and operated under the same climate conditions. The first is the traditional hemispherical solar distiller (THSD) which represents the reference distiller. The second is a hemispherical distiller with red brick tiles filled with cement set at a gap distance of 6 cm. The third is a hemispherical distiller with red brick tiles filled with cement set at a gap distance of 4 cm. The results presented that, the utilization of red brick tiles filled with cement with a height of 2 cm and a gap distance of 4 cm represents a good choice that achieves the highest performance of hemispherical distillers.The results showed that the utilization of red bricks filled with cement will be improved the accumulative yield from 4.3 L/m 2 /day (THSD) to 6.55 L/m 2 /day with an improvement of 52.3%. Also, using the red bricks filled with cement improved the thermal and exergy efficiencies by 51.24% and 435.5%, respectively compared to THSD.hemispherical distiller, natural low-cost storage materials, performance improvement, red bricks filled with cement, thermal and exergy efficiencies | INTRODUCTIONPure drinking water is considered one of the most important and indispensable elements to ensure the survival of all living organisms on the planet. [1][2][3] In recent years, as a result of rapid population growth, rapid industrial development, environmental pollution, and pollution of many surface waterways, especially in developing countries, the amount of fresh water suitable for human use has become insufficient. There are many countries around the world suffering from the problem of lack of fresh water. To obtain fresh water, it is necessary to treat polluted water and treatment seawater, and groundwater. Where, water treatment mainly depends on energy. Therefore, solar energy is considered one of the most acceptable alternatives for energy supply, and this is agreed upon by many researchers. [4][5][6] Therefore, the use of solar energy is an effective option Abbreviations: PCM, phase change materials; HSD & RBC, hemispherical solar distiller with red bricks filled with cement; THSD, traditional hemispherical solar distiller.
