To date, dozens of pilot-scale microbial fuel cell (MFC) devices have been successfully developed worldwide for treating various types wastewater. The availability and configurations separators are determining factors the economic feasibility, efficiency, sustainability, operability these devices. Thus, concomitant advances between MFC deserve further clarification. analysis separator has shown that their evolution proceeds as follows: from ion-selective to ion-non-selective, nonpermeable permeable, abiotic biotic. Meanwhile, cost is decreasing increasing. Notably, novel MFCs configured with biotic superior those in terms wastewater treatment efficiency capital cost. Herein, a highly comprehensive review (>100 L) conducted, we conclude intensive stack liquid cathode configuration more advantageous when highest priority. use permeable ensures hydrodynamic continuity within simplifies reactor operation. In addition, systemic comparison conducted conventional decentralized processes. showed comparable cost, higher long-term stability, significant superiority carbon emission reduction. development greatly contributed usability MFCs, which will play an important role scenarios future.

A nature-based closed-loop wastewater treatment system at vehicle-washing facilities: From linear to circular economy

iScience, Journal Year: 2024, Volume and Issue: 27(4), P. 109361 - 109361

Published: March 6, 2024

Pakistan, among the top five most water-stressed nations globally, grapples with water scarcity owing to inadequate treatment infrastructure and groundwater overextraction. We demonstrate a successful nature-based closed-loop system treat wastewater from urban vehicle-washing facilities, previously reliant on groundwater. An eco-friendly integrated containing floating wetlands (FTWs), subsurface flow constructed (SSF-CWs), sand filtration (SF) was designed installed at three facilities for reuse in loop. While is still operational after years, consistent significant reduction quality indicators recorded, successfully meeting national environmental standards of Pakistan. By reducing per unit costs as low $0.0163/m³ achieving payback periods under year, embrace these strategies vividly underscores imperative transitioning circular economy domains resource conservation.

Ecological filter walls for efficient pollutant removal from urban surface water

Environmental Science and Ecotechnology, Journal Year: 2024, Volume and Issue: 21, P. 100418 - 100418

Published: March 26, 2024

Urban surface water pollution poses significant threats to aquatic ecosystems and human health. Conventional nitrogen removal technologies used in urban exhibit drawbacks such as high consumption of carbon sources, sludge production, focus on dissolved oxygen (DO) concentration while neglecting the impact DO gradients. Here, we show an ecological filter walls (EFW) that removes pollutants from water. We utilized a polymer-based three-dimensional matrix enhance permeability, emergent plants were integrated into EFW facilitate biofilm formation. observed varying aeration intensities within EFW's aerobic zone resulted distinct gradients, with optimal control at 3.19 ± 0.2 mg L
