IntroductionGreater growth of population and industries results in shortage of fresh water. Earth is almost covered with a larger water source and smaller land mass. People used to drink large amount of water for their thirsty need. Water available in the form of rivers, lakes cannot be consumed directly without pre-processing, as these need some purification process in order to remove bacteria and undissolved salts. In early days the possible method of getting pure water is heating the brackish water and condensing them back to get fresh water by burning fossil fuels. Due to the exhaustion of coal, crude oil and increases in global warming, the evolution of using renewable energy for getting fresh water evolved during the late 20th century. One of the best energy source applied is solar energy. Source of energy from sun is mostly environmental friendly and non polluting clean energy source. Basin type still is the most aged process of producing fresh water [1][2][3][4][5][6][7][8][9][10]. The fresh water conversion rate from the solar still system is predominantly depends on the solar intensity. The basin water temperature increases continuously due to heat energy emitted from the sun in the form of solar intensity. After reaching the boiling point of water, the water evaporates and it condenses on the solar still condenser cover. The various techniques employed in solar still, to raise the temperature of water and hence increases the productivity was studied from the detailed literatures reviews of Ravishankar et al. [11], Kabeel et al. [12] and Manokar et al. [13][14][15]. From the detailed literature studies it is clear that water temperature can be improved by either feeding waste warm water or pre heat the water by incorporating the different solar collectors or concentrators. Gupta et al. [16] theoretically analyzed the intermittent flow of waste warm water to the double basin solar still similarly same analyses was done by Yadav et al. in single basin solar still [17]. Sodha et al. [18] and Tiwari et al. [19] experimentally investigated the performance of solar still utilizing the warm water from the industry. Tiwari et al. [20] keep up a higher temperature difference between the water and collector cover by increasing the water temperature by flowing waste hot water in the basin and decrease the collector cover temperature by flowing the cold water above the surface of collector cover. This would results in increase in both evaporation and condensation

“…Desalination technologies have been used to provide fresh water to crews for almost a century [2]. Among the different common desalination processes like multi-stage flash (MSF), multiple-effect distillation (MED), vapor compres-sion (VC), and reverse osmosis (RO) processes are commonly practiced to supply drinking water [1,[3][4][5][6]. But these technologies demand high energy consumption, high costs of desalination as well as inconvenient to carry.…”

Air bubble has been proved that it can increase evaporation area and coefficient of mass transfer and heat transfer. Two-stage evaporation system can indirectly increase the contact area of water and vapor, reduce the volume of single evaporation system, and can also combine the multiple systems flexibly. So a new type of small scale two-stage photovoltaic-photothermal humidification-dehumidification (HDH) desalination system is designed, and the relationship between solar radiation and temperature is measured, and the water production capability of the system is investigated. The effect of water temperature, ambient temperature, air flow rate and air temperature on desalination performance is also investigated. The results showed that the rate of water production is positively correlated with sea water temperature, ambient temperature, gas flow rate and air temperature. And the gas temperature is positively correlated with the solar radiation intensity. When the ambient temperature is higher than 25 ℃, the cumulative amount of irradiation is 22.3 MJ/m2, the cumulative water production is 19.2 L/d, and 6.4 L/( m2∙d), the thermal efficiency is 0.66. The cost of water produced through the designed HDH system is 0.08 $/L.
