Drawing of process
Protective filter:
The filter Gross with a module B520-12 (CB) is installed at the entrance of the
installation to protect the RO membrane from influence of active chlorine. It is made
of sintered powdered activated carbon in a polymeric matrix (technology Carbon
Block).
The filter gross 20” with
module PP5 micron is installed after the CB filter to prevent
particles larger than 5 microns to enter the RO system. Filter element is made of
polypropylene. It is necessary to replace regularly the filter modules in order to keep
the water feed rate, and also to avoid ingress of chlorine, solid particles in the
membrane modules
Replacement instructions: Shut off the system from electricity, make sure there is no
pressure (relief the pressure if needed), put a container under the system, with special
key open the housing of Gross. Remove the old module, pour the water. If necessary,
wipe the housing and the top cover. Install the new module. Set back the housing
vertically, tighten the nut of the housing by hand and gently close it with a key.
After replacement, inspect the modules by opening slightly the CIP valve , switch on
the system and close after a few seconds.
