Long Term Storage Procedures
Watermakers are best run frequently (every other day is ideal), 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 great-
ly 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, SC
-
1 Storage Compound has to be mixed at a ratio of 1 Spectra container to 3 gal-
lons (12L) of fresh water to have the proper solution. An average of 6 gallons
(22L) of water is in the system. This water has to be figured in to the mixture
using two packets of SC
- 1.
Caution! Avoid contact with skin, eyes, or lungs with the storage chemical.
