Water Purification through the Ages

Water Purification through the Ages

The process of removing containment, sediments and undesirable chemicals from water is called water purification. The water is purified to make it fit for various use like drinking purpose, industrial, medical and more. In the process of purification, the water passes many steps like filtration, sedimentation and then distillation. There are both biological and chemical methods to perform these processes. Purification reduces the chances of suspended particles, viruses, and bacteria from the water. The process of water purification also helps in rainwater harvesting. The biological processes include slow sand filter and active carbons; the chemical method uses ultraviolet for processes like chlorination and flocculation.

Water purification processes with passing time

The citation of water purification and treatment go back to 2000BC and is very fascinating. Primarily it was to make the taste better, but with the detection of various water-borne diseases, the processes shifted to the purification of water to remove microbes and bacteria from water.

2000 BC:

Writings are cited back to 2000 BC in ancient Greece and India where water treatment records are found. People had knowledge that boiling water purifies it and they also had the knowledge of gravel and sand filtration and straining.

1500 – 1300 BC:

The principle of coagulation was discovered by the ancient Egyptians. The tombs of Ramses II and Amenophis II contain techniques of purification. These paintings show wick siphons and sedimentation apparatus. It is debated that they used alum to remove the sediments from water.

500 BC:

Hippocrates, the Father of Medicine, invented a technique which id called ‘Hippocratic sleeve,’ the first ever cloth bag filter to sieve rainwater. The prime purpose was to filter sediments the caused odors. It was one of the first man-made filters.

300 200 BC:

Skilled Romans built the first aqueducts which were a water supply system giving birth to water supply system towards the end of 3rd century BC; this storage was built to remove silt through sedimentation.

500 1600 AD:

Due to the lack of scientific innovation in the Dark ages, little progress was made towards water treatment. The aqueducts were destroyed after the fall of Roman Empire.

17th – 18th CE:

Water treatment saw a new way with Sir Francis Bacon with seawater desalination experiments through a method of sand filtration. In 1680 with the invention of the microscope and the design of the first multiple filters, water treatment had a future and observation of microorganisms in water was first made. In 1764 the first patented filter design by Parisian scientist Joseph Amy made of sponge, wool and charcoal came to market.

19th 20th CE:

In the 1870s the diseases caused by water organisms was demonstrated by Dr. Robert Koch and Dr. Joseph Lister. America built sand filters to protect from waterborne diseases like typhoid and cholera. The U.S. Civil war caused some glitch in these developments. Scientist discovered water disinfectants. 1906, ozone was used as a disinfectant in France. Read more here.

21st CE:

In 2003 first water processors were marketed for filtration and development of water. Today the main focus is on the removal of lead from water which can cause cancer and much more.

So, Cuckoo Water Purifier has introduced natural mineral system that benefits us to drink healthy to our lifestyle.

Thus, the next time you switch open that water purifier, think about all that steps that took place in the history to make water so safe, get dizzy with thoughts, drink a glass of water and switch off the water purifier to reduce water wastage.

Save water!
