History of the Water Filter - 2

Advent Of Domestic Filtering Applications

It was around the 1700s when the first domestic water filters for home use were applied. They were made of charcoal, wool, and sponge. However, it was in 1804 that the first municipal water treatment plant was designed in Scotland by Robert Thom. The water treatment system was based on sand filtration.

It’s was in 1827 when John Doulton and Henry (his son) came up with the concept of the ceramic water filter that removed harmful bacteria from drinking water. Dubbed the Doulton filters, the first ones were made of clay and earth materials.



First Water Filter Patent

Joseph Amy got the first water filter patent around the mid-1700s. His design incorporated charcoal layers, wool, and sponge to help in purifying drinking water. In 1750, the first home water filters for home use became available.

In 1862 came the Doulton Manganous Carbon Filter which tapped into Louis Pasteur’s advancements in microbiology and his research into bacteria. The Manganous Carbon Filter is among the first carbon cartridge filters. In 1906, John Doulton introduced a water filter that compared favorably to the one developed by Louis Pasteur in France.
