Ural Federal University (UrFU) power engineers recently developed a new desalination technology that will reduce the cost of desalination and quadruple the volume of production. The results of the research are published in the journal Case Studies in Thermal Engineering. Today one of the most popular and simple ways of desalination is the distillation of the water with help of solar energy. UrFU scientists, together with colleagues from Iraq, have developed a hybrid technology to increase the efficiency of evaporation inside a solar distiller by means of a rotating hollow cylinder and a solar collector.We created a desalination technology by using a rotating hollow cylinder inside the solar distiller to accelerate water evaporation in the vessel by forming a thin film of water on the outer and inner surface of the cylinder, which is constantly renewed with each turn. To increase the temperature of water under the cylinder we use a solar collector said the head of the department Nuclear power plants and renewable energy sources UrFU Sergei Shcheklein. As part of the experiment, the rotation speed of the cylinder inside the solar distiller was 0.5 rpm. This intensity and time are enough to evaporate a thin film of water from the surface of the cylinder. Experimental tests were held in Ekaterinburg, Russia for several months (June-October, 2019) and

showed high efficiency and reliability of the developed device. In addition, the researchers noted that the relatively high intensity of solar radiation and low ambient air temperature also contributed to the performance of water distillation.
