methods of water purification ancient to modern

The rate of settling of a particle in water depends on the viscosity and density of the water as well as the size, shape, and specific gravity of the particle. Joan Reinbold is a writer, author of six books, blogs and makes videos. Clean drinking water is so widely available today that many people take it for granted. The Romans, Greeks and Mayans all used aqueducts to keep water pure. Owing to the fact that people utilize water for activities such as washing and waste disposal, and irrigating crops, it is easy for sources of water near a human population to get contaminated. Running the water through sand is also suggested in a few ancient Sanskrit and Egyptian texts. As they wrote in Nature ‘The apparent zeolite filtration system at Tikal’s Corriental reservoir is the oldest known example of water purification in the Western Hemisphere.’ They also found evidence of the first use of zeolite in the Maya water purification system. Risk assessments were enabled after 1990. He called this invention the water screw. You need to drink water to survive.

It’s a good method to use for water contaminated by living micro-organisms. In Greece, a fabric bag, called the Hippocrates Sleeve, was used to strain water before boiling it. The outbreak seemed less severe in areas where sand filters were installed. Improvements made included taste and how the water looked, though some types of bacteria could elude those methods. Some of the methods adopted include, Winnowing: water polluted by wind borne impurities like leaves, stalks and coarse substances is passed throw winnowing (5) sieve. Suspended inorganic particles found in water have a specific gravity ranging from 2.65 for discrete sand particles to about 1.03 for flocculated-mud particles. Experimentation of two Dutch spectacle makers experimented with object magnification led to the discovery of the microscope by Antonie van Leeuwenhoek in the 1670s. He grinded and polished lenses and thereby achieved greater magnification.
