What Technologies are Available for Water Purification?
Over the recent past water purification technology used to purify water has experienced some rapid changes. Here’s a brief look at some of the different methods of water purification available today.
One of the oldest methods used to distill water is distillation which has not yet been abandoned. 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. Anything that has a higher boiling point than the liquid or cannot be vaporized in the steam remains in the first pot.
This is one of the methods of water purification that leaves the minerals behind and causes an acid pH. According to researchers Acid PH levels as well as demineralization is not good for people’s health.Demineralization of water as well as acidic PH water is not good for one’s health.

Advancements in water purification technology have aimed at removing chemical and biological contaminants, without destroying the natural mineral content and pH level.
A Simple Plan For Researching Water
Reverse osmosis is often touted as the latest in water purification technology, when in fact it has been around for at least 50 years. This method is however specifically designed for use in large scale treatment facilities. It is only in the 1970 that this method was recognized as one of the safest method of water purification.
Moreover the method was popularized because it involved salt removal. Since most communities living in the islands and the coastal region drank salty water this technology greatly relieved them. Basically, it works by pressurizing and forcing liquids through a porous membrane. it is the size of the porous that determines what passes through it.
RO is another of the methods of water purification that de-mineralizes, so not the healthiest for drinking. apart from demineralizing the water, this method also has several other disadvantages.
It creates wastewater that cannot be used for drinking or other purposes. The other disadvantage is that this method requires a lot of electrical energy.
There are various other advancements that are used to remove all the threats not eliminated by the other technologies. Before adopting a method, one should study all those presented above.
carbon filtration is one of those new technological advancements in water purification. Chemicals and other contaminants stick to the filter, making the output safer to drink. This method also removes odor and improves taste. all the new water purifiers found in the home utilize this technology.
This article therefore provides a brief overview of various technologies used in water purification. It would be impossible in an article of this length to cover the subject in its entirety, but hopefully, you are now a little more informed.
