A Glimpse into the Development of Water Purifier Technologies

Ancient Beginnings

The pursuit of clean water dates back thousands of years.

In ancient times, people already had basic methods to purify water.

For example, they used specific containers to hold water.

Some containers were made of materials that could adsorb certain impurities to a certain extent.

Additionally, simple filtration through sand and gravel was also a common practice.

People would pour water through layers of sand and gravel, which could filter out larger particles and some suspended substances in the water, making it clearer and safer to drink.

The ancient Greeks and Romans were known to use sand filters to clean water.

In ancient China, there were also records of using natural materials to purify water, demonstrating that even in early civilizations, humans recognized the importance of clean water for survival and health.

The Leap into Modern Times

The 17th century marked the beginning of significant progress in water purification technology.

In 1685, the first documented water filter was invented, which was a simple device but laid the foundation for future developments.

As science and technology advanced, more sophisticated water purifier technologies emerged.

In the 19th century, the use of charcoal in water purification became more widespread.

Charcoal has excellent adsorption properties, capable of removing certain odors, colors, and some chemical impurities from water.

This was a major step forward in improving water quality.

The 20th century witnessed revolutionary breakthroughs.

RO technology uses a semi – permeable membrane to filter out impurities, including salts, heavy metals, and microorganisms, by applying pressure to force water through the membrane.

This technology can produce highly purified water and is widely used in various fields, from desalinating seawater to purifying drinking water in households.

Another important development was the introduction of ultrafiltration membrane technology.

Ultrafiltration membranes have pores that can effectively remove bacteria, viruses, and large – molecule impurities while allowing beneficial minerals and some small – molecule substances to pass through, providing a balance between purification and retaining beneficial components in water.
