In this paper, a dome slope single basin solar still for water treatment and desalination is presented. This new solar still device is based on installing a dome slope cover on the walls of the solar still. The main objective of such still is to concentrate more sunrays at the still's bottom basin, through the increased area of dome glass cover. Experiments are conducted under the climate conditions in Hangzhou city, China, for testing the operational performance of dome slope type solar still and the fourfold slope still, so as to make a comparative analysis between them. Assessment of the dome slope still's feasibility is performed based on energy, exergy, exergoeconomic, and enviroeconomic methodologies, as well as energy payback time. Results show that the productivity of dome slope still is 36% higher than that of fourfold slope still, and dome slope solar still enhances the average hourly energy efficiency by 34%. Due to the higher energy and exergy outputs of dome slope solar still throughout its lifetime, the novel solar still proposed in this study mitigates more CO2 compared to the fourfold slope still. Overall, incorporation dome slope cover with the still is found promising in terms of freshwater yield, cost, and energy payback time compared to conventional one. The dome slope single basin solar still appears to be effective from exergoeconomic, exergoenvironmental parameters analysis.

Generally, coil-tubes are utilized to extract heat from solar ponds. There are different coil-tubes in which their thermal and hydraulic characteristics depend on configuration and geometrical parameters. In this study, the performance of three well-known coil-tubes, namely helical, colubrine, and spiral, as the core of solar ponds is investigated at both smooth and twisted forms. Moreover, different levels of coil-pitches and twist-lengths are examined to explore the effects of geometrical parameters.

“…Meanwhile, the replacement of renewable energy fossil fuels such as solar energy has been welcomed to reduce energy costs and reduce pollutant emissions 6 . Fortunately, Iran has very good insolation intensity in most areas, because it is located between the circuits 25°–40° north latitude 7 . This requires the implementation of solar plans and allows the use of solar energy in cities and 60,000 dispersed villages in the country.…”

Lack of fresh water is a concern for the future of human because commonly used technologies for producing drinking water from saline water, such as reverse osmosis, electrolysis has been expensive to produce and or, like flash techniques and multi‐stage distillation, are dependent on the fossil energies. In this study, the shallow solar basin has been proposed to simply collect and store solar thermal energy to produce drinking water from salt water. Also, the use of nano particles increases the rate of evaporation in the shallow solar basin. In this way, the experiments have been conducted to optimize the efficient factors in the operation of a shallow solar basin equipped with a nano plate at the bottom of the pool. This shallow solar basin is concentrated in saline water and produces distilled water as the main processing stage for distillation of zero discharge. In this way, concentrated saline water prepares the inflow for evaporation units. The main parameters such as insolation rate, values of produced drinkable water and average temperature of shallow solar basin layers are investigated in this study. The comparison between evaporation rate values in a shallow solar basin equipped with nano plates and conventional solar basin shows an increase of 20%. The results show better performance of the proposed shallow solar basin than the simple shallow solar basin. The test results show the maximum and minimum evaporation rates of 5 and 2 L in June and January 2019, respectively.
