Reverse osmosis can remove microorganisms such as viruses and bacteria?
2021-12-14
Reverse osmosis (RO) membrane is very dense and has a very high removal rate for viruses, phage and bacteria, at least 3logs (removal rate>99.9%). However, in many cases, it should be noted that microbial recurrence may still occur on the product water side of the membrane, it depends on the way of assembly, monitoring and maintenance. That is to say, the ability of a system to remove microorganisms mainly depends on whether the system is designed, operated, and managed properly, not the nature of the membrane element itself.
