Stable to Chlorine
Yes
No
Chlorine eliminates biofouling to reduce energy, downtime, and cleaning that damaged membrane

Surface Features
Smooth
Rough
A rough surface traps contaminants that results in fouling/clogging
pH Range with High
Salt Rejection
2 - 12
5 - 10
Wider pH range with high rejections adds capability

Cleaning Cycle
Short
Long
Less Downtime: More durable membranes can be cleaned faster without risk of damaging them.
