"Removal of microbiological contaminants: Reverse osmosis manufacturers claim to reduce levels of bacterial and viral contamination in the feed water by factors of 10(3rd power) to 10(5th power).
However, in reality reverse osmosis should not be relied upon to produce sterile, much less water with reduced bacterial levels.
Using the biological process called MITOSIS, Bacteria and viruses may rapidly penetrate the reverse osmosis membrane through defects and imperfections in the membrane as well as through tiny leaks in seals of the membrane module. In order to prevent colonization of the product water side with bacteria and proliferation of these bacteria, regular disinfection procedures are necessary(unfortunately most of which are never explained to consumers, and still fewer undertaken by owners of home use reverse osmosis systems).
In general, because of this marked deficiency in system capabilities, most of the reverse osmosis industry(dealers and salespersons included) doggedly try to steer the discussion away from this sensitive topic.\
Contrary to what most if not all of the industry consultants and manufacturers are saying about this subject, controlled, clinical studies have been done which indicate massive bacterial re-growth problems in PROPERLY MAINTAINED in-home reverse osmosis units. (insert Canadian medical journal reference here).
What this Canadian government-sponsored study showed was an incredible increase in gastrointestinal illnesses which were directly correlated with the higher levels of bacteria appearing in the test reverse osmosis systems.
Comparisons were made with neighbors who drank straight tap water. The neighbors did not experience the types of illnesses which were occurring in their neighbor's homes who owned the reverse osmosis units.
One can easily see why the US reverse osmosis industry has been strangely silent on these studies---studies which expose one of the more dangerous aspects of employing reverse osmosis in home use situations.
Much like the salt refining industry and water softener manufacturing and sales organizations, reverse osmosis industry representatives and their paid consultant organizations are continually attempting to ally fears of such microbiological contamination problems.
As seen in another part of this website, reverse osmosis is a terrific performer in industrial applications, when combined with other technologies such as mixed bed de ionization and where microbiological problems can be dealt with through the use of high powered ultraviolet and ozone systems.
Endotoxin aggregates have a high molecular weight of the order of 2 million and are well rejected by reverse osmosis membranes. However, endotoxin fragments may penetrate reverse osmosis membranes. These fragments may carry toxic components to the home drinking water and may endanger specifically those with reduced immune system characteristics.
Placement of a reverse osmosis system(without auxiliary processing capabilities such as ultraviolet or ozone) in a rural environment which is naturally prone to a wider and greater concentration of microbiological hazards is also cautioned.
Individuals who purchase point of use systems such as reverse osmosis need to be aware of both the capabilities and deficiencies of these systems."

"Nonetheless, reverse-osmosis systems are very effective at removing minerals, but are not as effective at removing bacteriological hazards."
