    Default Cleaning RO membranes?

    Just trying to get some advice. Planning on doing some maintenance on my
    unit, which has never been backflushed in the three years I've had it. and
    since this unit doesn't have a backflush kit available, I was wondering if
    it is possible to pull the membrane out of its housing and clean it, say
    with acetic acid, and/or peroxide. Any suggestions?

    You can pull out the membrane, using pliers. The housing can be washed
    with vinegar and water. The membrane can be soaked in vinegar water but
    I only recommend that if you are in a real pickle. The membrane is
    typically good for 3 to 5 years, so you *might* consider inserting a new
    one in the housing once it is all clean, while you have it pulled apart.

    Thanks for the info. I will likely try the vinegar solution first, since
    I have to buy the other filters, and don't have the bucks to shell out for
    a new membrane right now. If the vinegar doesn't work as expected, I'll
    have to consider buying a new membrane. Again, thanks.

    Is the vineger wash valid for all types of membranes? CTA, TFC, PA
    (polyamide), etc

    Not being sure what type of membrane I have, I simply rinsed it as best I
    could and put it back in the housing after I sterilized the rest of the
    unit.

    Yea that's a good point you brought up, especialy since
    the "a" in cta stands for acetate ie vinigar. Meaning it
    was made with acetic acid, so I might well be dammaged by
    acetic acid.
