Title: Help Please - RO Problem?
Post by: D.Salkeld_Ltd on April 30, 2007, 10:20:58 pm

Hi All,

Tonight I have put a new RO membrane in my 100gpd RO Man RO unit.

However after flushing well and leaving to run to drain the TDS out won't go below 19!  With a new membrane I usually get 2.

Anyone had a simular problem and know what to do?

Thanks

David Salkeld

David,
when I upgraded from a 100 to 200 gpd my second membrane was giving a higher reading than the first, I contacted ROman who suggested I remove the membrane and reseat it just in case it wasn't quite "in". This then lowered the reading from the second membrane, maybe try this to see if it helps ;)

John,

Thaks for your reply.  I tried that - still the same - contacted Cleantech today and Mike thinks there may be a hairline crack in the caseing ???  Going to get another caseing and see if that works - if not - must be the membrane :(
