The most important commodity in the world is water because no form of life on earth can exist without it. It covers more than seventy percent of the planet but clean water is a scarce resource. In fact, many people especially those living in developing countries lack access to clean water. This dire state of scarcity in clean water should remind us that water is precious and conserving it is important. We can appreciate its importance by learning a few things about what it takes to treat it. For instance, the elaborate process of water treatment through reverse osmosis membranes is worth knowing.
- The Process of Reverse Osmosis
Reverse osmosis is the process of removing contaminants from unclean water. These contaminants come out of the water as dissolved gases but safe gases such as carbon dioxide and oxygen remain in it. Pesticides, solvents, trihalomethanes (THM’s) and volatile organic compounds (VOC’s) are some of the contaminants that reverse osmosis remove from unclean water. The process is quite useful when it comes to industrial complexes as it helps industries to recover salts from industrial processes, clean up waste-water and convert brackish water. It is also useful in homes where unclean water pushes through a reverse osmosis membranes that trap contaminants and then allow clean water to pass through them.

- Understanding These Membranes
Reverse osmosis membranes are simple yet effective scientific marvels that help us to purify unclean water in our homes and industries. These membranes can trap tiny microorganisms, salts and other particles in water even though conventional water treatment mechanisms cannot. These membranes can come in various materials such as thin film composite (TFC), cellulose triacetate (CTA), sulphonated polysulphone (SPS) and cellulose acetate (CA). Each membrane has a different quality depending on the materials used to make it e.g. TFC membranes are durable, CTA membranes tolerate chlorine easily while SPS membranes withstand environments with a high level of pH.
- Understanding Performance
Using a reverse osmosis system without understanding what can affect its performance is not advisable because you would not know how to improve its effectiveness. Four basic factors can affect the performance of this system i.e. incoming water pressure, water temperature, quality of filters, type of membranes used and the nature of the dissolved solids. Always keep the temperature at an optimum level, clean it regularly and use biocides when necessary. These steps will ensure that all is well with your system regardless of what system you use. Remember, reverse osmosis systems have the same components and therefore, they all work in a similar fashion.
- Difference between These Systems
As mentioned earlier, these systems look alike and work in a similar fashion but a clear difference exists when it comes to the membranes used. Different manufacturers use different membranes when they produce these systems. This means that you could have an inferior or superior membrane in your system so you should check on your membrane to make sure that it works perfectly. Only accept a system whose membrane is of the highest quality because that kind of membrane cleans your water thoroughly. Now you know more about reverse osmosis membranes. Use this knowledge to make a wise choice when buying and installing a water treatment system in your home. For more information visit: http://www.avistatech.com/
