Does an Reverse Osmosis system disinfect water?
While the membrane used in an RO system will physically screen out and remove many micro organisms in water, including pathogenic bacteria, the system must not be relied upon to make a biologically questionable water supply safe and potable for consumption. Membrane imperfections or faulty water seals in the system could allow untreated water to pass through and over time bacteria could grow on or through the membrane. Be sure the raw water source for your RO system is safe and potable for consumption by having a sample tested by a certified water testing facility.
