Improving the efficiency of using solar energy for desalination of salty and polluted water is an urgent task for many regions of our planet. The great strides made in this area using ultrafiltration and reverse osmosis techniques have a high energy intensity of technology, which is extremely expensive to achieve using photovoltaic solar energy converters. The creation of new desalination technologies that require low expenditure of electrical energy requires the use of other physical mechanisms. The joint use of thermal distillation methods with the intensification of evaporation and condensation processes by low-energy-intensive ultrasonic dispersants and thermoelectric refrigerators is promising.In the current work, an experimental investigation study was conducted to show the effect of enhancing the evaporation and condensation processes inside a modified single solar still by combined ultrasonic humidifiers in the basin water inside a cotton mesh tent, in addition installing at the top of the solar still a cooling chamber with thermoelectric elements Peltier. The results showed that the productivity of the modified solar still increased by 124% than the traditional solar still.
