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.
The liquid is first brought to its boiling point and then vaporized. A tube is connected which collects all the vapor and then cools it to become water again. Anything that has a higher boiling point than the liquid or cannot be vaporized in the steam remains in the first pot.
When using this method, all the minerals are left down at the first pot. It has been learned that for drinking purposes, de-mineralization and acid pH levels are not healthy.
Learning The “Secrets” of Resources
Advancements in water purification technology have aimed at removing chemical and biological contaminants, without destroying the natural mineral content and pH level.
Valuable Lessons I’ve Learned About 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 technology was developed to be used in large scale industries and 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. In coastal areas and island communities, this is an important and desirable feature. The method works by forcing liquids to pass through a porous membrane. The size of the holes determine what pass? through the membrane.
The other method of purifying water is known as the RO. apart from demineralizing the water, this method also has several other disadvantages.
This method creates wastewater that cannot be used for any other purpose. It operates slowly and requires electrical energy.
New advancements in water purification technology for the home are aimed at removing those threats. It is very important to first go through all the methods available before settling on one.
Lets take an example of carbon filtration that is used nowadays to purify water. The output of this process is safer to drink because all the chemicals and other contaminants stick on the filter. 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. Since it is impossible to cover everything in an article like this, My only hope is that you have been informed.
