Powder Membrane Preservative
Preservol™ membrane preservative allows
membranes to be safely stored
Preservol™ powder membrane preservative allows
membranes to be stored for short and extended periods
without loss of performance.
As a powder, Preservol™ is more convenient to store,
easier to handle and may be transported more
economically. This product is reliable at extreme
temperatures and has an extended shelf-life, maintaining
product stability long-term.
Preservol™ is safe for use on polyamide thin-film
composite membranes, cellulose acetate membranes,
nanofiltration and ultrafiltration membranes.
Product Application
• Long Term Storage
Thoroughly clean membranes with Lavasol™ or
OptiClean™ membrane cleaners.
• Short Term Storage
Mix 1 pound of Preservol™ to 6 gallons of good quality
water such a RO permeate.
• Polyamide Thin Film
Recirculate solution for at least 15 minutes. A recirculation
pressure less than 60 psi is recommended. If possible,
avoid permeation.
• Cellulose Acetate
• Hollow Fiber
After recirculation, shut-down the system. Do not allow
the Preservol™ solution to drain from the membranes.
The membranes may then be stored in the system
vessels or they may be removed and stored in separate
containers.
• Nanofiltration
• Ultrafiltration
To use membranes after storage, first rinse them for 30
minutes using good quality water such as DI or RO
permeate.
