Implication

Randomized trial demonstrates improved antifouling and permeability in polyaniline-blended membranes, suggesting effective cleaning strategies.

Key Points

This research aims to explore the effects of polyaniline blending on ultrafiltration membrane properties and evaluate a cleaning method for fouling reduction.
Characterization of PES/PAni·DBSA membranes using SEM, BET, AFM, and TGA.
Measurement of initial water flux, BSA rejection, and flux recovery ratio in a dead-end filtration cell.
Application of electrochemical cleaning to evaluate post-cleaning performance.
Initial water fluxes varied from 5.9 to 39.3 L·m−2·h−1 across different membrane compositions.
The best-performing membrane recovered 8.12 times its initial flux after cleaning.
Electrochemical treatment led to significant increases in both flux and BSA rejection, confirming effective foulant mobilization.
