RE: RO membranes
Thanx for answers.
I bought a new membrane and now... it work great again ;))))
The guy from the original membrane couldn't test only the membrane, he asked
for pre-filters too...
What's this for an idiot ? (OK, a 'biological food' shop... but R/O is
R/O...)
Well, the system I have is like this one http://www.ampac1.com/ap-ro3.htm
but with 2 tanks.
It's quite easy BTW with auto shut-off valve.
I noticed some black particules on the tank of the membrane (like carbon I
would guess)
Could it be coming from the carbon prefilter ?
To be sure, I exchanged the pre-filters order, so now I have: carbon,
sediment, membrane.
Do you know where I could find future membranes ?
A 35 GPD is about 100$ here in Belgium
I saw some around 60$ on the net but they don't see shipping conditions.
