*Product flow and recovery rates are based on feedwater conditions of 2000 ppm TDS at 77°F. Treatment ability of the RO system is dependent on feed water quality. Higher TDS and/or lower temperatures will reduce product flow. An AXEON Applications Engineer can rate the units for these other feed water conditions.    

**A concentrate recycle loop is available as an option to increase recovery to 75 to 80% (if suitable to feed water conditions).    

***Other voltage options are available.

****Appropriate filtration must be installed in order to prevent premature membrane fouling.    

*****Scale prevention measures must be taken to prolong membrane life.
