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.
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.
6. SRC MCC-3, Membrane Cleaning Compound "#
3" is used for iron fouling. It is not included in
the SRC Membrane Cleaning Chemical kit. If the
system's R.O. membrane element is fouled with
rust from iron piping, then SRC CC-3 may be
used for effective removal of light or moderate
rust fouling. Heavily rust fouled RO membranes
may not be recoverable as rust not only fouls
the Membrane Element but also damages the
membrane surface.
WARNING: DO NOT mix different
chemicals together. DO NOT use
different cleaning chemicals together
at the same time. Mix the cleaning
chemicals separately and use them
separately. Use only Sea Recovery
supplied chemicals. NEVER use third
party non-Sea Recovery chemicals.
