Different Kinds of Water Purification Systems

Water is an integral part of life. Without clean water, society as we know it will succumb to disease and death. The importance of drinking water systems in order to purify water for the purpose of removing contaminants and other unwanted particles cannot be stressed enough. Here are some of the different kinds of water purification systems available.

Reverse Osmosis

Since the early 1970s this method of water purification has been used with much success commercially. The process of reverse osmosis was applied initially to remove salt from seawater so as to make it potable. Osmosis refers to the tendency of water to move from a weak saline solution to a much stronger one. In reverse osmosis, the water is manipulated so as to move it from a stronger saline sample to a weaker one utilizing a semi-permeable membrane. Salt molecules are much larger when compared to water particles and thus the membrane simply does not allow it to pass through. Once, the process is done, the desalinated water and the heavy saline solution are separated on either side of the membrane. Apart from salt molecules, there are also other contaminants that can be removed thanks to this process.


The process of purifying water through filtration has been around since ancient times. However, the process has evolved to a point that it can be done extremely efficient to ensure that the result is clean water. Activated carbon treatment systems for instance, are just one of the ways by which the contaminants are removed with excellent results. The filtration begins through the installation of a carbon filter which will act to block contaminants from passing through unimpeded. The process is augmented by treating the water with chemicals prior to undergoing filtration.


This water purification method calls for using heat in order to vaporize water. The process separates pure particles of water from contaminants that possess a higher boiling point than water. Once the water evaporates, the next step is capturing the evaporated water by allowing it to pass through a system of tubes. The steam condenses back to water minus the contaminants.
