Sea Recovery Aqua Mini 170, Owner'S Manual

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 results from silt, coral dust, river or inland waterway debris, or other small solid matter.
R.O. Membrane Element Cleaning Water and Chemical Requirements
1. The system must be rinsed with fresh water before any cleaning procedure.
2. The process of rinsing and cleaning the R.O. Membrane Elements requires 20 gallons / 76 liters of fresh non-
chlorinated product water.
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.
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 in excess of 1000 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.
Caution: CAUTION: DO NOT MIX DIFFERENT CLEANING CHEMICALS TOGETHER.
DO NOT USE DIFFERENT CLEANING CHEMICALS TOGETHER AT THE SAME TIME. MIX THE CLEANING
CHEMICALS SEPARATELY AND USE THEM SEPARATELY.

1. Close the Cock Valve [2].
2. Replace the Pre-filtration Cartridge with a new SRC supplied Pre-filtration Element.
3. Configure the system for a Once Through Rinse.
4. Fill the 5-gallon container full with non-chlorinated product water. The bucket must contain enough product
water to rinse the system until all of the feed water is displaced.
5. Open the Back Pressure Regulating Valve [17] fully open counterclockwise.
6. Operate the system by pressing the “Start” switch. The rinse water rinses the entire system and discharges out
to waste.
