Water Purification The Recent Technological Advancements and Historical Developments
Water purification technology has advanced tremendously in the past few years, particularly in the area of home filtration systems. Here’s a brief look at some of the different methods of water purification available today.
Distillation is very old water purification technology, but it is still commonly used. This method was first developed as a method of creating alcohol only. These alcohol distillers were found by archeologists in southern Asia countries during excavation. The process is very simple and involves the following.
Liquid is brought to a boil and it vaporizes. This vapor enters a tube whereby it cools down to become liquid again. The other contents that may be in the water mainly have higher boiling point than water and as a result, it remains in the first pot.
The method causes acid PH and leaves all the other minerals down. It has been learned that for drinking purposes, de-mineralization and acid pH levels are not healthy.
On Purifiers: My Experience Explained
Advancements in water purification technology have aimed at removing chemical and biological contaminants, without destroying the natural mineral content and pH level.
6 Facts About Purifiers Everyone Thinks Are True
Despite the fact that reverse osmosis has been in existence for 50 years it is considered to be one of the latest technologies. It was developed for use in industries and large scale treatment facilities. In the 1970s, it became popularized as one of the healthiest methods of water purification for the home.
This method mainly involved removing salt. This feature was most desirable in island and coastal communities. The method works by forcing liquids to pass through a porous membrane. The size of the pores determines what is removed and what travels through.
The other method of purifying water is known as the RO. The system however, has several other disadvantages.
It creates wastewater that cannot be used for drinking or other purposes. It operates slowly and requires electrical energy.
Over the past, there has been other technological advancements that were developed to eliminate all the other threats. One should first consider all the methods and then select the most suitable.
carbon filtration is one of those new technological advancements in water purification. It operates in such a way that chemicals and other contaminants stick on the filter and as a result the water that emerges from the process is safe to drink. This method also removes odor and improves taste. Most of the newest home purifiers make use of this technology.
This article therefore provides a brief overview of various technologies used in water purification. It is impossible to cover everything in this article, my only hope is that you have grasped something.
