Patent N° PR2006A000062
Water filtration
in 4 technological steps
The studied system, tested and carried out by Bertoli and Pall Corporation implies
4 filtration steps :
 Trap filter: it implies the usage of a 3μm absolute filtrating element, suitable to
remove the particles and incidental impurities that can arrive through the
pipelines.
 Pre-filter: it implies the usage of a 1μm absolute filtrating element, that, thanks to
its electropositive charge, is suitable to remove the siliceous or metal (aluminum)
colloidal elements.
 Final filter : it implies the usage of a 0,2μm absolute filtrating element with a
double diaphragm. This filter is defined as an absolute sterilizing filter as being
validated on the basis of FDA regulations.

Patent N° PR2006A000062
Sterile water generator for
piston seals lubrication
Patent N° PR2006A000062
The sterile water generator present on the equipment aims at reducing the
bacteriologic level in the water by microfiltration.
Softened water from osmosis system with a conductibility between 10 and 30 microS/cm and a temperature between min 10 and max 50° C should be used for the
generator, in order to avoid premature filters obstruction.

Patent N° PR2006A000062
Water filtration
4° step of guarantee
• According to FDA regulations, a filter can be considered a sterilizing one
when it is able to remove 107 bacterial cells of Brevundimonas Diminuita
(block ATCC19946) for any square cm of filtrating surface of the filter. The
DFL filtrating element is able to remove, with security degree, 1013
bacterial cells of such an microorganism for any square cm of filtrating
surface.
• The fourth filtration step:
• Bertoli Srl, in order to offer to its Clients a further guarantee, installs a
second passage with the same filter of 0,2um.
