II.1 Storage precautions
PREVENTION OF CHEMICAL ATTACKS ON THE SYSTEM
Do not use for storage purposes, or expose the unit to, hydrogen peroxide, chloramine,
chloramine-T, N-chloroisocyanide, chlorine dioxide, hypochlorite, chlorine, iodine,
bromine, bromide, phenolic disinfectants or any other chemical element. The use of
unauthorized chemical elements, or the abuse of authorized ones, will invalidate any
warranty.
TEMPERATURE: Never expose the membrane during its storage to temperatures
higher than 50ºC or lower than 0ºC. Never store the membrane vessel under direct
sunlight. Freezing temperatures will result in mechanical damage to the system due to
the expansion of air on freezing. This will cause irreversible damage to the membrane.
DRYING OUT: Never allow the membrane to dry out. If the membrane dries out, up to
30% of production flow will be lost. It would cause irreversible damages to the
membrane. The membrane must always be kept damp.
BIOLOGICAL DIRT: Protect the membrane from biological dirt. Up to 40% of
production flow will be lost if the membrane gets dirty with biological slime. Some
production, but not all, can be recovered by following a thorough cleaning.
CHEMICAL DIRT: Protect the membrane from chemical attacks or dirt. Be careful
when using the system in ports that may be polluted with chemical products, oil or fuel.
Chemical attacks are not covered by the warranty.
STORAGE: The inside of the membrane, which is dark and damp, is an excellent place
for microorganisms to reproduce. When the membrane is used, tested or operated
intermittently, it is exposed to microorganisms. Up to 50% of production flow can be lost
if the membrane is not stored correctly.
