Methods of solar distillation have been employed by humankind for thousands of years.
2.
Phase change ( or multi-phase ) can be accomplished by either direct or indirect solar distillation.
3.
In 1870 the first US patent was granted for a solar distillation device to Norman Wheeler and Walton Evans.
4.
One of the five demonstration plants constructed was located in Daytona Beach, Florida and devoted to exploring methods of solar distillation.
5.
In the 1960s and 70 s several modern solar distillations plants were constructed on the Greek isles with capacities ranging from 2000 to 8500 m 3 / day.
6.
Techniques include boiling, filtration, activated charcoal absorption, chemical disinfection, ultraviolet purification, ozone water disinfection, solar water disinfection, solar distillation, homemade water filters.
7.
Production data shows that MSF solar distillation has an output capacity of 6-60 L / m 2 / day versus the 3-4 L / m 2 / day standard output of a solar still.
8.
Techniques include heat ( including boiling ), filtration, activated charcoal absorption, chemical disinfection ( e . g . chlorine, iodine, ozone, etc . ), ultraviolet purification ( including SODIS ), distillation ( including solar distillation ), and flocculation.
