Who Invented Water Filtration? 

Throughout the centuries, humans have used various types of filters to ensure that they have clean and healthy drinking water. The first known attempts at water filtration are thought to have occurred thousands of years ago. Early Greeks and Assyrians tried to clean water by heating it over a fire or by filtering it through gravel. Archimedes, a Greek engineer, was the first to develop a water screw. He originally used it to lift water from ship bilges. Today, the water screw is still used to transport water.

Hippocrates, the Greek physician, was the first to discover the healing properties of water. He also designed a crude water filter that was made out of cloth. The water filter acted like a sieve and was used to remove sediments, odours, and bad tastes from the water. It is often referred to as the Hippocratic sleeve. 

Around 500 BC, Hippocrates invented the water sleeve and began using it to filter water. He boiled the water and poured it through the cloth, then filtered it through the sleeve. In fact, the Hippocratic sleeve was the first bag filter ever made. 

The use of the water sleeve led to other water filtration systems, including aqueducts. In the 18th century, many towns started installing municipal filters to provide filtered water to the people living there. 

By the mid-19th century, most cities in the world were taking steps to purify their water. They introduced several types of filtration techniques, including ozone and chlorine. These two treatments were particularly useful during World War II. When added to the water, chlorine eliminated cholera outbreaks and made the water taste better. 

While early water filtration techniques were successful, there was a problem: there was no way to know if the water was free of contaminants. Scientists and researchers started to look for ways to improve the treatment process. Several methods were found, including flocculation, chlorine injection, and aeration. 

Another successful treatment method was the sand filtration method. During this time, the concept of microorganisms in water was discovered, and scientists began to study how to treat these particles. This gave them new insights into the water. 

Adding chlorine to the source of water was a major turning point in the development of water filtration technology. Bacon’s experiments did not work well, but they sparked interest in the field. Other scientists soon followed in his footsteps. 

One of the most successful experiments of the late 1700s was conducted by Sir Francis Bacon. He attempted to remove salt particles from sea water. His experiment failed, but it laid the groundwork for other researchers to get involved in the water filtration industry. 

Eventually, the idea of using a microscope to inspect the water was discovered. Microscopes allow humans to see microscopic organisms, and this information helped them find a solution to the water filtration problem. 

Water filtration techniques continued to be developed in the 1800s and into the 1900s. The Safe Drinking Water Act passed in 1974, which paved the way for the development of even more advanced water treatment systems.
