Advanced Tertiary Wastewater Treatment for Enhanced Effluent Quality by Electrically Conducting Membranes Operated at Altered Potential for Simultaneous Mitigation of Scaling and Biofouling

ACS ES&T Engineering, Journal Year: 2024, Volume and Issue: 4(8), P. 1902 - 1913

Published: April 29, 2024

Electrically conducting membranes (ECMs) present a promising low-fouling technology for advanced tertiary wastewater treatment, particularly when employed as cathodes to resist biofouling. However, the elevated pH levels near cathode lead severe scaling. This study investigated alternating applied potentials in carbon-nanotube-based ECM simultaneously mitigate biofouling and scaling while producing high-quality effluent. The research demonstrates that −2.5 V cathodic 1.5 (vs Ag/AgCl) anodic at 5 s intervals significantly reduce In 48 h filtration experiment using real secondary effluents, there was notable decrease trans-membrane pressure by 110 mbar, contrasting with 320 mbar increase observed under open-circuit potential (OCP) conditions. Surface analysis confirms absence of biofilm on layer operation, contrast high formation OCP low attributed controlled limited measured reactive oxygen species, facilitating bacterial detachment. short duration may also carbon nanotube (CNT) oxidation extend lifetime. ECM-based produced higher-quality effluents than conventional chlorination-coagulation-sand-filtration treatments. These findings highlight sustained efficient surpassing current treatment technologies.
