Routine Maintenance
4.3.1 Pre-Cleaning
Preparation
There are two types of cleaners available, a low pH cleaner (Calcium/Iron removal) and
a high pH cleaner (Silt/Organics removal). GE Osmonics provides these cleaners in
liquid form. The low pH cleaner attacks mineral scale deposits such as calcium,
magnesium and iron build-up, and should be used first. The high pH cleaner will
remove accumulated silt and organic matter from the RO membrane.
CAUTION:
The different cleaners must not be mixed together. Introduce the low pH cleaner
first, thoroughly rinse the system, and then use the high pH cleaner.
WARNING:
The solution is a mild irritant to eyes and skin. It is recommended that protective
gloves and eye protection be worn when handling the cleaner. Neither respiratory
protection nor special ventilation are required.
