Long Term Storage Procedures
Desalination systems are best run frequently as biological growth in the membrane is
the leading cause of membrane fouling. A warm environment will cause faster growth
than a cold environment. The fresh water flush system will greatly reduce biological
growth but may not stop it completely in certain conditions.
System Storage for up to 6 months, “Pickling”
If the system is to be left unused for more than 2 weeks , perform the following
storage procedure. The procedure introduces a chemical compound, SC-1, into the
system that prevents biological growth.
Spectra SC-1 is a special storage compound used by the US Navy. It is formu-
lated to be compatible with the modern engineering plastics and composites
in the Spectra pumps. Do not use any substitute except Propylene Glycol.
Caution! Avoid contact with skin, eyes, or lungs with the storage chemical.
