- •
Membrane exposure to chlorine increased polyamide membrane surface hydrophilicity.
- •
Solute passage increased to a greater degree by convection relative to diffusion.
- •
Severity of membrane degradation was quantified by equivalent breach size.
- •
At same chlorine ppm-hr membrane degradation increased with concentration.
