History of water purification
Documentation of water treatment dates back to 2000BC, where water was boiled and strained to clean it. The first domestic filter to be made was by the Greek scientist Hippocrates, called the Hippocratic sleeve around 500BC. This was a simple cloth back filter.
Only in 1627, did an interest in water purification occur in the form of Sir Robert Bacon, who began experimenting with sand filtration to remove salt particles from sea water.
The invention of the microscope provided the insight of microorganisms present in water, this sparked the use of domestic water filters made of wool, sponge and charcoal in the 1700.
In 1854 the British scientist John Snow discovered that cholera was transmitted through water and could be treated with chlorine. This led to the use of chlorination in water purification.
In the 1900 water regulations by most governments was being endorsed and there was room to look at quality of water that was being produced.
Currently in 2000, there are many methods to purify water. There are two main questions we can ask ourselves?
