What
are the proper storage conditions for membranes? What is the shelf-life of
a membrane?
Please refer to our Technical Article:
Biological Fouling on Membranes - Storage, Shipping
and System Shut-down.
What
lubricant should I use for the seals on pressure vessels and filter
housings?
You will need a special lubricant so as to not damage the membrane in your
system. This product is sold by our online distributor, and can be found on
http://www.wateranywhere.com
. The product part # to search for is H-C111DC. Here is a direct link to the

How do
you eliminate the unpleasant taste and odor that may be coming from the post
carbon filter?
You will need to remove the filters and membrane from the system, sanitize
with chlorine and flush. Then replace with new filters.
What is
the density of the membrance for Residential Thin Film Membranes? (ie. 0.001
-- 0.0001)
0001 micron "pore size".
What is
AM-11?
AM-11 is one of the membrane cleaners we sell. It is generally used for
cleaning larger membranes but some companies have used it also to clean
smaller residential membranes.
Why is
the performance different in different flow rated residential membranes? (24
gpd, 36 gpd, 100 gpd, etc.) The membranes look the same even the number of
times rolled up.
The useful area of the membrane material is different in the two sizes. They
look the same because of the difference in membrane area is made up by other
fabrics.
What
is the difference between dry and wet membranes?
When the thin-film membranes manufactured they are dry. These dry membranes
have an indefinite shelf life, when stored properly. Membranes become wet
when they are flushed or tested with water. Once wet the membranes can not
be dried. The wet membranes must be preserved to prevent the growth of
micro-organisms on them. This is done usually by using a 1-2% solution of
sodium metabisulfite. For more details look for information on storing
membranes. |
