2 Use of caustic soda alone will result in the slight discoloration of the membrane and
extraction of F- ion, however, there is no deterioration in the physical properties of
membrane. Therefore, the cleaning of module by caustic soda alone should be limited
and use of caustic soda with sodium hypochlorite is recommended.
There is no requirement for detection instrumentation for the referenced chemicals. Appropriate
temperature sensing equipment should be installed to insure that modules are not exposed to
temperatures above 40 degrees C.
