ELEMENT STORAGE PROCEDURE
R.O. MEMBRANE ELEMENT HANDLING &
SYSTEM STORAGE CAUTIONS:
TEMPERATURE CAUTION: Never expose the HRO
R.O. membrane(s) to storage temperatures above 122
°
F /
50 C or below 32
°
F / 0 C. Never store the R.O.
membrane assembly in direct sunlight. High temperature
causes up to 40% flux loss (loss of production) of the
R.O. membrane element(s). This damage is irreversible.
Freezing temperatures cause mechanical damage to the
HRO system. This damage is irreversible to the R.O.
membrane element.
DRYING OUT CAUTION: Never allow the R.O.
membrane element to dry out, as 40% flux loss occurs.
This damage may be irreversible to the R.O. membrane
element. The R.O. membrane element(s) must remain
wet at all times.
BIOLOGICAL FOULING CAUTION: Protect the
R.O. membrane element from biological fouling. Up to
40% flux loss occurs if the element becomes fouled by
biological slimes. Some, but not all, flux may be
regained after thorough cleaning.
CHEMICAL FOULING CAUTION: Never expose
the R.O. Membrane Element to chemicals other than
those supplied by HRO. Use caution when operating the
System in harbors that may be polluted with chemicals,
oil, or fuel. Chemical attack to the R.O. Membrane
Element may damage the element beyond repair.
Chemical attack of the R.O. Membrane Element is not
covered by warranty.
STORAGE CAUTION: The interior of a membrane
element, being dark and moist, is an excellent breeding
ground for microorganisms. Simply operating the system
does not protect the R.O. Membrane Element(s) from
biological fouling. Up to 40% flux loss due to biological
fouling occurs in the element if it is not stored properly.
During short-term shutdowns the membrane element
must be rinsed as explained in the following pages.
During long-term shutdowns the membrane element must
be rinsed as well as chemically treated as explained later
in this chapter.
NEW SYSTEM STORAGE CAUTION: The Horizon
Seafari system has been tested at the factory and rinsed
with a mild mixture of storage chemical. This allows the
system to be stored for up to 3 months if kept in a cool
place. Do not store the system for longer than 3 months
prior to actual use. If storage of the new system is longer
than 3 months the system must be rinsed with fresh water
and restored with storage solution every 3 months
otherwise biological fouling and or drying out damages
the R.O. Membrane Element.
