Electrocatalytic Upcycling of Nitrate Wastewater into an Ammonia Fertilizer via an Electrified Membrane

Environmental Science & Technology, Journal Year: 2022, Volume and Issue: 56(16), P. 11602 - 11613

Published: July 21, 2022

Electrochemically upcycling wastewater nitrogen such as nitrate (NO3–) and nitrite (NO2–) into an ammonia fertilizer is a promising yet challenging research topic in resource recovery treatment. This study presents electrified membrane made of CuO@Cu foam polytetrafluoroethylene (PTFE) for reducing NO3– to (NH3) NH3 (NH4)2SO4, liquid ready-use. A paired electrolysis process without external acid/base consumption was achieved under partial current density 63.8 ± 4.4 mA·cm–2 on the cathodic membrane, which removed 99.9% feed (150 mM NO3–) after 5 h operation with rate 99.5%. energy 3100 91 g-(NH4)2SO4·m–2·d–1 21.8 3.8 kWh·kg–1-(NH4)2SO4, respectively, almost outcompete industrial production cost Haber–Bosch process. Density functional theory (DFT) calculations unraveled that situ electrochemical conversion Cu2+ Cu1+ provides highly dynamic active species reduction NH3. demonstrated achieve synergistic decontamination nutrient durable catalytic activity stability.

Technologies for the wastewater circular economy – A review

Desalination and Water Treatment, Journal Year: 2024, Volume and Issue: 317, P. 100205 - 100205

Published: Jan. 1, 2024

Throughout the years, experiments with membrane, electrochemical, biological and thermal technologies have been explored to recover resources from a range of wastewaters such as municipal, industrial, urine sewage sludge. However, multiple resource recoveries at commercial pilot scale are still lacking, instead, focusing on specialising recovery narrow set products. Herein, divergence across municipal industrial wastewater streams – nutrients energy for municipal; heavy metals water streams; material seen both was observed through literature review. This review aims provide perspective academic professionals alike current available their emerging trends tie in these circular economics. Consequently, high sludge transportation costs may pressure treatment plants (WWTPs) adopt value-adding, onsite transforming centralised decentralised WWTPs into facilities.

Electrochemistry-stimulated environmental bioremediation: Development of applicable modular electrode and system scale-up

Environmental Science and Ecotechnology, Journal Year: 2020, Volume and Issue: 3, P. 100050 - 100050

Published: June 26, 2020

Bioelectrochemical systems (BESs) have been studied extensively during the past decades owing primarily to their versatility and potential in addressing water-energy-resource nexus. In stark contrast significant advancements that made developing innovative processes for pollution control bioresource/bioenergy recovery, minimal progress has achieved demonstrating feasibility of BESs scaled-up applications. This lack demonstration could be ascribed absence suitable electrode modules (EMs) engineered large-scale application. this study, we report a scalable composite-engineered EM (total volume 1 m3), fabricated using graphite-coated stainless steel carbon felt, allows integrating into mainstream wastewater treatment technologies. The cost-effectiveness easy scalability provides viable clear path facilitate transition between success lab studies applications solve multiple pressing environmental issues at full-scale.
