Can reverse osmosis remove microorganisms such as viruses and bacteria?

Reverse osmosis (RO) is very dense and has a very high removal rate of at least 3log above (>99.9%) against viruses, bacteriophages and bacteria. But also must pay attention to is that in many cases, the film is produced water side still may appear microbial breeding, again depending on the assembly, the monitoring and maintenance way, that is, a system of key depends on the ability of removing microbes proper system design, operation and management rather than the nature of the membrane element itself.
