M-100 Storing Procedures
M-100 safely and effectively
prevents microbiological growth within
membrane elements and systems
during long- and short- term storage.
It replaces the use of formaldehyde,
sodium metabisulfate and other
chemicals that are typically used.
While formaldehyde or sodium
bisulfite are either hazardous or
unstable, M-100 is effective for long-
term and does not create
environmental or health risks. M-100
is compatible with all membrane types
and rinses easily from membranes.
A conductivity meter can conveniently
monitor the completeness of rinsing to
the background conductivity of the
rinse water. M-100 is packaged as a
dry, stable, non- reactive powder for
ease of transportation and storage.
In Storage
1. Clean the membranes with AXEON C-10 or C-20 cleaners prior to
storage. Using good quality water (RO product water), mix at a ratio
of one pound M-100 to 6 gallons of water.
2. Recirculate storage solution at low pressure (less than 60 psig)
through membranes for minimum of 15 minutes.
3. After re-circulation, shut system down making sure storage
solution does not drain out of membranes.
4. After storage, rinse membranes with good quality water for 30
minutes before system start up.
Container Storage
1. Clean membranes with AXEON C-10 or C-20 cleaners.
2. Using good quality water (RO product water), mix a ratio of
one pound M-100 to 6 gallons of water. Place membranes in
storage container containing M-100 solution.
3. After storage, place membranes in system and rinse with good
quality water for 30 minutes prior to system star-up.
