Top 5 Things You May Not Know About Water Purification Systems
1. The French cleric Jean-Antoine Nollet made the important discovery that water naturally diffuses from a dilute to a concentrated solution in 1748. This phenomenon later became known as osmosis. During the following century, the study of osmosis became of particular interest to practitioners of the biological and medical sciences.
2. Robert Barnstead, a master plumber, developed the first all-metal laboratory distillation unit for Massachusetts General Hospital in 1878.
3. In 1907, Heinrich Bechhold published a paper on the process known today as ultrafiltration. Bechhold described driving solutions at high pressures through a membrane prepared by impregnating filter paper with acetic acid. He used the term ultrafilter to describe a collodion membrane of graded pore size. Ultrafiltration is now commonly understood to mean a process that allows colloidal particles, emulsions and microorganisms to be removed from a solution.
4. The use of ultraviolet (UV) light treatment was first attempted in the United States as a method to purify drinking water in 1916.
5. From 1926 to 1931, key research was performed on the phenomenon of reverse osmosis by various researchers, including Michaels, Manegold and McBain.
