Solar distillation process begins with water vaporization after that the water condensate on cooler surface then this condensate water runs off to collection bin. There are some patent researches.The objective of this thesis is to develop water distillation technology that uses plentiful and free solar energy by utilizing different functional nanomaterials. Double layered functional materials (exfoliated graphite and carbon foam) were used for sunlight absorption and heat localization which enable significantly improved water evaporation efficiency.In this research, a greenhouse connected to a solar distiller device was constructed for the desalination of saline water and irrigation at Shahid Chamran University of Ahvaz. Sand, sand-bagasse-perlite, and bagasse-perlite beds were used in the greenhouse as a condenser of hot and humid air of the distiller tank. By measuring air.

An effort has been made to review all the available research and technology for water distillation using solar energy in this research paper.
Solar water distillation is the process of using the energy from sunlight to separate freshwater from salts or other contaminants. The untreated water is placed into a still basin which absorbs heat, eventually reaching high temperatures, causing the water to evaporate, cool and condense into vapour, leaving the contaminants in the underlying basin.
The present paper focuses on a unique combination of solar dish cooker (SDC) and solar water heater (SWH) to produce distilled water with a high distillate and a high daily productivity. The procedure has been discussed on the basis of experimental testing to produce distilled water by combining an evacuated type SWH and a SDC.
Desalination is an inter-disciplinary journal publishing high quality papers on desalination materials, processes and related technologies. Desalination welcomes submissions detailing work that is clearly connected to water desalting including applications of desalination to seawater, groundwater and waste waters, such as thermal, membrane, sorption and hybrid processes.
This paper deals with a global analysis of the use of solar energy in seawater distillation under Spanish climatic conditions. Static solar technologies as well as one-axis sun tracking were.
Abstract- This research paper covers different types of low cost solar water desalination techniques. This paper also describes methods for solar water desalination process at large scale with less cost. Keywords- solar water desalination, sea-water desalination, brackish water desalination, low cost water desalination, water purification.
Heat the water, and the process speeds up. In a solar still, seawater, dirty water, or even green leaves are set inside a transparent plastic container, which can be as simple as a polythene bag.
One particularly expensive process is the distillation of the azeotropic mixture ethanol, toluene, and water. Newly released research conducted by Lei Zhao, Xinyu Lyu, Wencheng Wang, Jun Shan, and Tao Qiu showed that two new distillation processes could be used to vastly lower a company’s total annual cost of distilling these products.
Solar distillation is a relatively simple treatment of brackish (i.e. contain dissolved salts) water to convert fresh water. Distillation is one of many processes that can be used for water purification and can use any heating source. Solar energy is a one best option. In this process, water is evaporated; using the energy of.
This paper presents the design, construction and experimental study of a pure mechanical parabolic trough sun tracking device for solar distillation systems. It describes a novel design that uses a typical mechanical clock sun tracking system.
Solar Energy Desalination Technology explains how to obtain clean water from sea water using solar energy. Special methods and types used in solar desalination are introduced, providing new thoughts, concepts, and feasible solutions in the desalination field, along with the thermal and economic efficiency relating to current technology.
Solar disinfection (SODIS) was developed in the 1980s to inexpensively disinfect water used for oral rehydration solutions. In 1991, the Swiss Federal Institute for Environmental Science and Technology began to investigate and implement SODIS as a household water treatment option to prevent diarrhea in developing countries.
Experimental Analysis and Optimization of Solar Water Distillation System. Present paper is an investigation in variation of water yield in single slope solar water still system attached with additional solar collector. This work has been carried out in a clear sky day in month of Feb, 2016.
