2. The process of rinsing and cleaning the R.O.
membrane elements with just one cleaning
compound requires 30 gallons (113.5 liters) of
fresh non- chlorinated product water. If a second
cleaning is performed using a different cleaning
compound an additional 20 gallons (75.7 liters)
will be required per additional cleaning.
3. The Sea Recovery Reverse Osmosis cleaning
compounds are designed to clean in a closed
loop configuration moderate fouling from the
R.O. membrane element. If the R.O. membrane
element is excessively fouled and in-field
cleaning is not successful, the R.O. membrane
element may be returned to Sea Recovery or
to one of Sea Recovery’s many Service Dealers
for professional chemical cleaning. If your
membrane requires professional cleaning, please
contact Sea Recovery for a Return Authorization
Number, price quotation, and return instructions.
Due to the complexity of and time involvement
in professionally cleaning the R.O. membrane
element it can be more cost effective to replace
a heavily fouled R.O. membrane element. Always
compare the cost of cleaning vs the cost of
replacement in order to make the proper decision
to clean or replace.
4. SRC MCC-1, Membrane Cleaning Compound
“#1” is an alkaline cleaner designed to clean
biological fouling and slight oil fouling from the
R.O. membrane element. Biological fouling is
usually the first cause of the R.O. membrane
element fouling. The system is constantly exposed
to seawater and biological growth occurs from the
first day forward. If exposed to seawater and left
to sit, the R.O. membrane element becomes fouled
even with no actual system use. This fouling is
minimized with fresh water rinsing whenever the
system is not in use.
5. SRC MCC-2, Membrane 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 a
slow process which takes place during use of the
system. 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 several thousand hours
of use then there may be some mineral fouling
combined with biological fouling.
dried out prior to use. A NEW System experiencing
low production should be operated for up to 48 hours
continuously to clear and saturate the R.O. membrane
element and product water channel. Correlate and
compensate operating pressure, feed water temperature,
and feed water salinity as charted in the Section 2.
If a NEW System still experiences low production after 48
hours of continual operation, then contact the factory. If
a NEW System experiences poor quality Product Water,
high in salinity, this would be attributed to a mechanical
failure such as a broken or missing O-ring and will be
accompanied with high production at low operating
pressure. For problems with a NEW System refer to the
Troubleshooting section.
The membrane element requires cleaning from time to
time. Biological growth and salt accumulation eventually
make replacement necessary. The frequency of required
cleaning depends on the amount of production loss and
salt rejection loss resulting from normal use. In order to
properly assess performance changes, it is important to
maintain daily log readings for comparison.
During performance comparisons, Feed Water Temp,
Feed Water Salinity, and System Operating Pressure must
be taken into consideration and compensated for. After
compensations, a 10% decline in productivity (GPH Flow)
and/or a 10% increase in salt passage indicate that the
R.O. membrane element may require cleaning.
If production rate has dropped dramatically since the last
time the system was used, this may be due to drying
out of the R.O. membrane element and/or fouling during
storage. If the system has not been used for several
months and the production rate has dropped dramatically
since the last time used, try operating the system for 48
or more continuous hours to saturate the Product Water
Channel within the R.O. membrane element.
If production rate drops dramatically from one day to
another, this may be due to chemical attack which is
not cleanable. Sewage chemicals or petroleum products
cause irreparable damage to the R.O. membrane
element. Suspended solids fouling resulting from silt,
coral dust, iron (rust), river or inland waterway debris, or
other small solid matter may not be cleanable.
R.O. WATER AND CHEMICAL REQUIREMENTS
1. The system must be rinsed with fresh water
before any cleaning procedure, cleaned, and then
rinsed again.
