Hippocrates believed that water had to be clean and pure. Rainwater was the best water, but had to be boiled and strained before drinking to get rid of the "bad smell" and to avoid hoarseness of the voice. [3] [4] He designed a crude water filter to “purify” the water he used for his patients. Later known as the “Hippocratic sleeve ...

The chlorination of the water supply helped stop the epidemic and as a precaution, the chlorination was continued until 1911 when a new water supply was instituted. [130] Manual Control Chlorinator for the liquefaction of chlorine for water purification, early 20th century. From Chlorination of Water by Joseph Race, 1918.
Filtration as a method of water purification was established in the 18th century, and the first municipal water treatment plant was built in Scotland in 1832. However, the aesthetic value of water was important at the time, and effective water quality standards did not exist until the late 19th century. [18]
Portable water purification devices are self-contained, easily transported units used to purify water from untreated sources (such as rivers, lakes, and wells) ...
This is typical of the lack of understanding of how disease was transmitted and followed the general belief that water courses such as rivers and lakes were great sinks for purification of contaminated water.

Slingshot is a water purification device created by inventor Dean Kamen. [1] Powered by a Stirling engine running on a combustible fuel source, it claims to be able to produce drinking water from almost any source [2] by means of vapor compression distillation, [3] requires no filters, and can operate using cow dung as fuel.
Purified water is usually produced by the purification of drinking water or ground water. The impurities that may need to be removed are: inorganic ions (typically monitored as electrical conductivity or resistivity or specific tests) organic compounds (typically monitored as TOC or by specific tests)
