HYDRAULIC SCHEME FOR SHUTDOWN PROCEDURE
FIG. 6-1
NOTE
The available products for the shutdown procedure are the following:
1) SCHENKER CLANING 1 (SC1 – Acid product) to remove the inorganic components and preserve the
watermaker during winter break
2) SCHENKER CLEANING 2 (SC2 – Alkaline product) to remove the organic components (mould and
bacteria) when already deposited; in this case the system becomes stinky.
Whether the system needs acid or alkaline cleaning will depend on the type of foulant suspected.
However, both are needed and it is recommended to start with the alkaline cleaning then follow with
the acid cleaning after the system has been flushed.
NOTE
Normally only SC1 is required, but in case of strong smell it is recommended to use also the SC2.
The sequence in this case will be SC2 first, then a washing of the system. Finally the SC1, then again
washing of the system.
It is advisable to replace the filters after performing shutdown procedure with new ones.
