Abstract
We evaluated transport-aware tuning for membrane desalination under 49% salinity gradient. A deterministic paired simulation generated 64 cases and preserved a upper-severity quartile. Mean flux-selectivity balance changed from 0.563 to 0.612; the paired difference was +0.050 (95% interval +0.048 to +0.052). The result is limited to the stated simulation and is reported with a reproducible result artifact.
