 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? | | | | | | | | 10-05-2005, 04:17 AM
Re: Cleaning RO membranes?
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.

Marine Hobbyist: http://www.melevsreef.com | 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. | | | | | | | | 10-06-2005, 05:15 AM

Kim Gross | 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. | | | | | | | | 10-06-2005, 11:52 AM
Re: Cleaning RO membranes?
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. Wayne Sallee Wayne@WayneSallee.com Quote: Is the vineger wash valid for all types of membranes? CTA, TFC, PA
