Anode–Cathode Synergistic Filter Activating Peroxymonosulfate at Multiple Active Sites for Highly Efficient and Economical Water Purification

. This process demonstrated excellent pH adaptability (4-14) for SMX removal, outstanding reusability, and continuous operation capability. Its resilience to wastewater matrix interference enables the efficient and economical treatment of both high-conductivity mariculture wastewater and low-conductivity municipal sewage with remarkably low electric energy (0.08-0.16 kWh/kg of COD). This approach offers promising prospects for addressing water pollution challenges across industrial and environmental contexts.
