How a Reverse Osmosis Water Purification System Works
There are several components to a reverse osmosis water purification system. This article is going to take a look at them and several options so that you can be better informed before deciding which system is right for you and why you should get one for your home.
Basics of a Reverse Osmosis Water Purification System
The word osmosis means the diffusion of water through a cell wall or membrane. Generally this movement of water is accomplished by have a solute concentration opposite a low salt concentration so that water goes from one system to another. This is not the case when looking at a reverse osmosis water purification system. This system uses the pressure of water coming into the home to facilitate this movement. The water is forced through a membrane which filters out the pollutants.
This brings us to the first part of the reverse osmosis water purification system. The membrane comes in two types – thin film composite and cellulose triacetate. Either of these membranes will work very well the main difference being that a TFC filter will take out more pollutants and a CTA filter will last longer. Either filter may be used and the overall functionality of the system is not changed depending on which one you go with.
In addition to the filter all reverse osmosis water purification systems have an array of granular activate carbon prefilters. These serve as the first step in filtering your water. Most older water filters only have this system and it can be found in you in fridge water filters as well. This water passes through the carbon granules where some of the impurities are picked up and removed. After this the water passes to the reverse osmosis membrane where it is further filtered. A typical reverse osmosis water purification unit will filter out anything above .0005 microns. This is much smaller than any cell or virus. Generally only very small particles will be able to pass though the filter.
After the water has passed through both the filters it is generally placed in a storage tank for later use. The size of the tank varies from unit to unit with larger being better for many reasons.
Usually also associated with the reverse osmosis water purification unit is the ability for the system to continually remove particles including bacteria, viruses, and other complex chemicals and taking this refuse and continually moving it away from the membrane keeping it free and clear to do its job.
