FORTILIFE™ CR100Fewer Cleanings are in Your Future.
• Lower CIP frequency caused by biofouling
by up to 50%* versus market standard
� more up-time, higher overall system recovery
� longer element lifetime
• Reduce energy consumption by up to 10%**
* Depending on feed water quality and operating conditions** At the same operating flux and recovery
It is achieved by applying an innovative membrane design that reducesdifferential pressure and bacteria adhesion significantly

FORTILIFE™ CR100 Pilot Study 2
Side-by-side field trial: two banks of 6 x 4 inch elements in series operated with matching flux and recovery. Nutrient dosed Wastewater (Tarragona, Spain)
� 29% reduction in CIP frequency *
*This is a pilot study; we recommend to follow FILMTECTM cleaning procedure
FORTILIFE™ XC seriesClean Less. Recover More.
11
FORTILIFE™ XC70 / XC80 Clean Less. Recover More.
• Reduce RO concentrate volume by up to 7%* to
achieve a higher membrane system recovery at
roughly 12.5%** of the cost.
12
* Depending on feed water quality and operating conditions
** Depending on specific brine concentration technology
It is achieved by combining Dow’s most permeable yet fouling-resistant membrane with easy-to-clean module construction.

FORTILIFE™ XC-NRecover More. Reduce Waste.
• Reduce costly RO concentrate waste by converting a
large fraction of it into purified, easier-to-crystallize
salt solution.
14
It is achieved by the use of a highly permeable and ion-selective NF membrane with high NaCl passage, and high divalent and COD rejection
