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.
8 STORAGE AND CLEANING
8.1 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
