MB-5 MEMBRANE CLEANING WITH DETERGENT
If the membrane has been fouled with oil it may be possible to save it by cleaning with
dish soap such as Joy, but do not use anything that contains bleach. You will need a
lot of chlorine free fresh water. If using shore water run it through a charcoal filter at a
rate of not more than 1.5 gallons (6 liters) per minute.
Use the “Membrane Cleaning Procedure”
Fill a bucket with fresh water and mix in a couple squirts of the detergent. Run the sys-
tem unpressurized (with pressure relief valve open) with the watermaker drawing water
from the bucket and discharging overboard. When about half the water is gone from
the bucket stop the unit and let the membrane soak for a few minutes. Restart and
pump the remaining solution overboard. Repeat until the discharge appears clean.
After most of the oil is cleaned out you can put the brine discharge into the bucket and
run the system with the soapy water circulating as you would for the other cleaning
chemicals. Run the Fresh Water Flush cycle to clean membrane, then flush for twenty
minutes using sea water. Pressurize and test.
