Ever wondered how a reverse osmosis system, also referred to as a ultra filtration system works, It's basic process involves the movement of water through a membrane which has microscopic openings that allow the water molecules, but not larger compounds, to pass through. Reverse osmosis systems are typically used to reduce the levels of total dissolved solids and suspended matter. Some membranes may also have an electrical charge that helps in reducing some chemicals at the membrane surface.
Originally developed for commercial use where mineral free water was required, a reverse osmosis system was a good solution to sterilize the water, removing all unwanted sediments and minerals. The result being what was considered clean, sterile water. These systems were readily available and quickly adapted for home use.
At the time that home based reverse osmosis systems were introduced, little research was done regarding water quality and its effect on our overall heath. The basic approach was to rid the water of the gritty heavy sediments and foul tasting minerals. No consideration was given to the other dangers that may exist. As we would soon discover, many sources of contamination were being found in our drinking water, leaky fuel storage tanks, manufacturing waste products and medical waste to name a few.
The effectiveness of these water filtration systems were soon called into question due to the fact they were never really designed to handle these types of contaminates. From a scientific perspective we soon realized that many of the compounds that were being analyzed were molecularly smaller than a water molecule and therefore would simply pass through the water filtration process.
This concern triggered more research which revealed that traces of more than 80,000 of what is now defined as SOC's or synthetic organic chemicals could be found in almost any public water supply. 2100 of these SOC's have been linked to diseases such as cancer and heart disease. It was now more apparent than ever that reverse osmosis systems were not the total answer to the ever increasing problem.
When evaluating reverse osmosis systems please keep in mind that the most effective system is one that utilizes a combination of processes. The best are those that incorporate a multi media filter process consisting of carbon filtration, ion exchange and sub micron filtration. This type of system will produce true healthy, great tasting water void of chlorine, lead and other SOC's (Synthetic Organic Chemicals). This process produces clean, pure water which has been stripped of harmful SOCs but retains optimal levels of essential minerals such as calcium and magnesium which are critical to our overall heath.
Now you know a reverse osmosis system is certainly a step in the right direction but may not necessarily be the best choice. Complete your research and determine which type of filtration system you feel will truly provide safe, healthy water for you and your family.
