How is nanotechnology used for water purification?

The world’s population is increasing at an exponential rate of 83 million people per year and has recently crossed the 8 billion mark.

The challenge of a growing population and unpredictable weather has driven researchers to develop innovative technologies that ensure humans and animals have access to safe drinking water. In an effort to ensure that the human population is not deprived of clean water, various nanotechnology methods have been developed to remove hazardous contaminants from drinking water sources.

What is nanotechnology or nanotechnology?

You have probably heard about nanotechnology or nanotechnology. This issue became a hot topic in the technology industry in the mid-2000s. For example, nanorobots, or microscopic robots, have become a staple of science fiction novels, TV series, and books.

Nanotechnology is the application of small machines that are used in all scientific fields. Richard Feynman, the famous physicist presented this concept in 1959. According to the website Alliance Waterwhile the term “nanotechnology” was not coined until the 1980s, Feynman had already proposed the idea of ​​controlling matter at the molecular level.

In nanoscience, phenomena are investigated at the nanometer scale. Nanotechnology includes materials with at least one component whose dimensions are less than 100 nanometers. Due to their nanoscale size, these materials are very different from conventional materials in terms of mechanical, electrical, optical and magnetic properties. The small size and large surface area of ​​nanomaterials make them highly absorbent and reactive. In addition, nanomaterials have very high mobility in solution.

Water and wastewater management companies are always looking for newer and more efficient ways to treat water. One of the most fascinating advances in water and wastewater treatment over the past 20 years has been nanotechnology. While most large-scale water and wastewater management operations have not used nanotechnology, the technology has shown promise on a smaller scale and could deliver clean water more efficiently than ever before.
