Chlorine Surge Protection

Chlorine damage is a common reason for low

performing membranes and premature membranereplacement.

A new Best Practice approach to prevent chlorine

from damaging RO membranes is to employ 3D

TRASAR Membrane Technologywith its built-in

Chlorine Surge Protection (CSP).

3DTfM with Chlorine Surge Protection uses a

fixed SBS dosage rate with an override feature

that will increase SBS dosage only after a

prescribed ORP high limit is detected.

This strategy delivers the needed amount of SBS

to quickly arrest chlorine excursions as shown in

the figure.
