Energy crisis and water born diseases caused by impure water are two major concerns of the present era. Various techniques have been used to make saline/brackish water potable. Filtration, precipitation, sterilization, chemical treatment, etc. are some processes that remove macro impurities from impure water. Distillation is thermal energy‐based process that effectively removes contaminants from impure water. Reverse osmosis is a membrane‐based technique widely used for the purification purposes. Electrodialysis, Ion‐exchange, and Freezing are some other processes used to get soft/distilled water for various commercial and domestic uses. Most of the desalination techniques utilize energy from the nonrenewable energy sources. Solar distillation is one of the solutions of getting potable water using solar energy. Solar distillation unit coupled with thermal collectors, photovoltaic panels, and concentrators makes the system active and increases the distillate three to six times than conventional units. Multistage, multieffect active solar still is observed to give an average distillate output of 20 kg/m2/d. Economic analysis also shows that active solar still is a good replacement of nonrenewable energy based water purification techniques. In this article, different water desalination techniques with their economic analysis are briefly discussed. Detailed comprehensive review of researches carried out on active solar still system considering their designs, performance parameters, different hybrid combinations, along with challenges, opportunities, future scope of improvements have also been highlighted. © 2017 American Institute of Chemical Engineers Environ Prog, 37: 444–464, 2018

Drinkable fresh water, being a fundamental need of human beings, has become a serious concern for people especially living in crowded cities and countries with limited amount of water resources. Supplying fresh water is an energy intensive task especially when there is need for heating cold water to evaporate for distillation. Most of the big desalination plants around the world use fossil-based fuels as energy source to heat and vaporize the sea water or brackish water in order to produce fresh water. However, environmental concerns along with decreasing oil reserves and increasing fuel costs call for reconsideration on the fuel types used in many areas as well as in desalination or distillation processes. There are a number of well-known alternative and renewable energy sources in the world like wind, geothermal, solar, biomass, etc. but achievability, availability when needed and energy storage are also very critical issues to operate the distillation plant effectively. Since most of the desalination processes run on heat, solar energy can be used directly as heat source. Complex desalination systems which are all designed to improve the thermal efficiency and freshwater yield/productivity use many approaches such as multiple stage operation, pre-heating the feed water with the condensation energy, using additional heat sources (waste water from another process), concentrating solar energy to improve the operation temperature of the process, etc. Solar desalination systems can be a good solution to the water scarcity, especially the Sunbelt region. However, dominant use of clean and renewable energy sources for desalination process and replacing the fossil fuel-based operations require more R&D studies to find more efficient and/or less costly power plants with continuous operation by the means of energy storage solutions.

“…External reflector plates [17] at different inclination angles were used to increase the radiation incidence on the solar still. Deniz [18] investigated the effect of parameters such as gap distance, slope of cover and cooling of the cover on the performance of the still. Anburaj et al [19] demonstrated an optimum 30°inclination for an inclined solar still with rectangular grooves which yielded 3.77 L/day fresh water.…”
