HRO CC-2 , Cleaning Compound “# 2” is an acid
cleaner designed to clean calcium carbonate and
other mineral deposits from the R.O. Membrane
Element. Mineral fouling is usually a very slow
process, which takes place over many hours of use.
Therefore, if the System has relatively few hours
of use yet shows signs of R.O. Membrane Element
fouling then that fouling is likely biological fouling.
If the System has in excess of 1000 hours of use then
there may be some mineral fouling combined with
biological fouling.
HRO CC-3
, Cleaning Compound “# 3” is used for
iron fouling only and is not included in the HRO CC
kit. If the HRO R.O. membrane elements are fouled
with rust from iron piping then HRO CC-3 may be
used for effective rust removal of lightly or moderate
rust fouling. R.O. Membrane Elements, which are
heavily fouled with rust may not be recoverable as
rust not only fouls the Membrane Element but also
damages the membrane surface.
CAUTION : DO NOT mix different
cleaning chemicals together at the
same time. Mix the cleaning chemicals
separately and use the separately.
8.6 R.O. MEMBRANE ELEMENT CLEANING
INSTRUCTIONS
1. Back Wash and rinse the Multi Media Filter, if
installed.
2. Close the Inlet Sea Cock Valve [2].
3. Replace all of the Pre-filtration Cartridges
with new HRO Systems supplied Pre-filtration
Elements. DO NOT INSTALL THE OIL/
WATER SEPARATOR ELEMENT AT THIS
TIME.
4. If not already connected, connect the RINSE/
CLEAN INLET line from the Rinse/Clean
Inlet Valve [4] to the pick up point of the
Rinse/Clean Tank [50].
The Rinse/Clean Tank should be minimum 10
to maximum 20 gallons in size.
5. Fill the Rinse/Clean Tank [50] full with non-
chlorinated product water. The cleaning
tank must contain enough product water to
rinse the system until all of the feed water is
displaced.
6. Position the Rinse/Clean Outlet Valve [4] to the
Brine Discharge (normal operation) position.
7. Open the Back Pressure Regulating Valve [33]
full open counter clockwise.
8. Operate the system by pressing the
“Start” switch. The rinse water rinses
the entire Horizon Seafari system and
discharges out to waste.
9. Just prior to depleting the rinse water from the
tank stop the system.
10. Refill the Rinse/Clean Tank [50] with 10 -20
gallons (38 - 75 liters) of non-chlorinated
product water.
11. Fill a separate plastic bucket or container (1/2
to 2 gallons) 1/2 full with product water. Add
the full contents of the HRO CC-1, CC-2, or
CC-3 Cleaning Chemical to the water in the
plastic bucket. USE ONLY ONE CHEMICAL
AT A TIME.
Mix and thoroughly dissolve the solution
in the container. Pour the dissolved
solution into the Rinse/Clean Tank [50].
NOTE
: The correct mixture ratio for the
Cleaning Chemical (CC) is one bottle per
20 gallons of product water. The chemical
is mixed first in a small bucket and then
added to the water in the tank. This
makes the chemical easier to dissolve into
the water in the tank.
12. Position the Rinse/Clean Outlet Valve [35] to
the Clean/Rinse Tank [50] return for a closed-
loop re-circulation to and from the Clean/
Rinse Tank [50].
13. Press the “Start” switch to begin re-circulating
the Cleaning Chemical solution from the
Clean/Rinse Tank, through the System and
back into the Clean/Rinse Tank.
Do not
pressurize the system above 50 psi maximum.
14. After approximately 60 minutes of re-
circulation, stop the system.
15. In order to empty the Clean/Rinse Tank,
position the Rinse/Clean Outlet Valve [35] to
the Brine Discharge, normal operating position.
16. Press the “Start” switch to discharge the
solution out the Brine Discharge Thru Hull
Fitting [36].
17. Just prior to depleting the Cleaning Chemical
solution from the tank, stop the system.
