Winterizing Procedure; Membrane Cleaning - Sea Recovery SRC Aqua Matic 450-1 Owner's Manual

4. Start the System in the MANUAL MODE
Operation of the System will deplete the Fresh
Water in the bucket. Just prior to depleting the
Water in the Bucket Touch STOP.
5. Once again, fill a 10-gallon (37.8 liters) container
with 10 gallons (37.8 liters) clean, potable water.
6. Add to the Fresh Water in the bucket or Fresh
Water and Propylene glycol, 4 ounces of Sea
Recovery Storage Chemical SRC SC.
7. Configure the system for a Recirculating Closed
Loop configuration as illustrated on Page 7-6.
8. Start the System in the MANUAL MODE
Operate the System in the Recirculating Closed
Loop configuration for 10 minutes. After 10
minutes stop the system:
9. Proceed to Section 7.5.

WINTERIZING PROCEDURE

If the System will be exposed to freezing temperatures
the Post Filtration Section of the System must be drained
of all Product Water.
a) Charcoal Filter
1) Remove the Charcoal Filter bowl.
2) Remove the water from the bowl.
3) Replace the Charcoal Filter Element with a
New Charcoal Filter Element.
4) Replace the bowl back onto the lid.
b) pH Neutralizing Filter
1) Remove the pH Neutralizing bowl.
2) Remove the water from the bowl.
3) Replace the bowl and pH element
back onto the lid.
c) UV Sterilizer
1) Disconnect the product water line from
the UV Sterilizer filter and drain the product
water from it.
1. Switch the Power to the System OFF.
2. Lock and Tag the Power Breaker to ensure that
no one will accidentally operate the System and
displace the Winterizing Mixture with Feed or
Fresh Water.
3. Discard the Storage Chemical in an
environmentally safe manner.

7.6 R.O. MEMBRANE CLEANING
Do not arbitrarily clean the R.O. membrane in a NEW
system. The R.O. membrane element in a NEW System
will not be fouled with any substance that is cleanable.
Low production or high salinity of the Product water
from a NEW System will be attributed to factors other
than fouling.
If a NEW system experiences low production this would
indicate that there is a blockage in the Product Water
Line, the feed water temperature is low, the operating
pressure is low, or the R.O. membrane element has
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.
