The evolution of Reverse osmosis (Part 1)

Did you know, that water makes up to 75% of human body weight. A loss of just 4% of total body water leads to dehydration, and a loss of 15% can be fatal. Likewise, a person could survive a month without food but wouldn’t survive 3 days without water. This crucial dependence on water broadly governs all life forms. Clearly, water is vital for survival, but what makes it so necessary?

No other molecule matches water when it comes to unique properties that support life. Excitingly, researchers continue to establish new ways to purify water depending on the quality of the water being treated, the cost of the treatment process, and the quality standards expected of the processed water.
The goal is to produce water fit for specific purposes. Most water is purified and disinfected for human consumption (drinking water), but water purification may also be carried out for a variety of other purposes, including medical, pharmacological, chemical, and industrial applications. It’s amazing how a simple molecule is universally important for organisms with diverse needs.

The first experiments into water filtration date back to the 17th century. Sir Francis Bacon attempted to desalinate seawater bypassing the flow through a sand filter. Although his experiment did not succeed, it marked the beginning of a new interest in the field. The fathers of microscopy, Antonie van Leeuwenhoek and Robert Hooke, used the newly invented microscope to observe for the first time small material particles that lay suspended in the water, laying the groundwork for the future understanding of waterborne pathogens.

Today researchers continue to perfect the methods and with modern technologies, water purification has improved amazingly. Some water purification methods like, Membrane filters are now widely used for filtering both drinking water, in commercial and industrial applications. For drinking water, membrane filters can remove virtually all particles larger than 0.2 μm--including giardia and cryptosporidium. Membrane filters are very an effective form of tertiary treatment when it is desired to reuse the water for industry, for limited domestic purposes, or before discharging the water into a river that is used by towns further downstream. They are widely used in industry, particularly for beverage preparation (including bottled water). Infect, reverse osmosis membrane systems is one of the most widely used methods today.

Reverse osmosis can remove many types of dissolved and suspended chemical species as well as biological ones (principally bacteria) from water, and is used in both industrial processes and the production of potable water. Follow us along the way, as we share knowledge from HID professional researchers on reverse osmosis membrane and system production. You are welcome with questions and also allow you to share your knowledge on the agenda, to help the water purification community gain vast knowledge o getting the best, safe, and quality water.
Without a comprehensive understanding of water’s true, multidimensional value, we will be unable to safeguard this critical resource for the benefit of everyone.
