The conventional Bio-Rack Wetland System (CBRWS) is a comparatively a novel technique for treating wastewater. It has potential to overcome clogging problem in constructed wetlands. Modifications are possible to enhance treatment potential of CBRWS with relatively lower cost. In the present study, modifications were implemented by planting multispe...

Application of microbial fuel cell (MFC) is coming to the forefront as a dual-purpose system for wastewater treatment and energy recovery. Future research should emphasize on developing low cost field-scale MFCs for removal of organic matter, nutrients, xenobiotic and recalcitrant compounds from wastewaters and powering low energy devices. For achi...

The frequent occurrence of surfactants in urban wastewaters represents a multifaceted environmental concern. In this investigation, bio-electro-Fenton-microbial fuel cell (BEF-MFC) was developed for degradation of sodium dodecyl sulphate (SDS) from wastewater. The synthesised cathode catalyst (powdered activated carbon and iron oxide) facilitated t...

Urbanization and industrialization have resulted in the escalation of the occurrence of emerging contaminants (EC) in the wastewater and ultimately to the receiving water bodies due to their bio-refractory nature. The presence of ECs in the water bodies adversely affects all three domains of life, viz. Bacteria, archaea and eukaryotes, and eventual...

The application of waste-derived iron for reuse in wastewater treatment is an effective way of utilizing waste and attaining sustainability in the overall process. In the present investigation, bio-electro-Fenton process was initiated for the cathodic degradation of surfactants using waste-iron catalyzed MFC (WFe-MFC). The waste-iron was derived fr...

Transition metal oxides supported on carbon have emerged as robust catalysts for energy recovery and environment applications, like fuel cells.

Calcium hydroxyapatite (HAp) is a naturally occurring material in bones of humans and calcareous animals. In the biomedical field, HAp has been extensively used due to their high biocompatibility and non-toxicity. These properties of HAp coupled with high surface area and adsorption capacity have prompted its application in wastewater remediation....

This investigation evaluated the efficacy of microbial fuel cell (MFC) employing cathode catalysed with reduced graphene oxide embedded on graphitic carbon nitride nanocomposite. The catalyst showed an excellent electrochemical response with a minimal charge transfer resistance of 11.5 Ω, compared to the conventional Pt/C (10.1 Ω). The physicochemi...

The rapid population boom, elevated living standards, and commercial activities have led to increased water contamination. One of the recent problems related to water contamination is the frequent detection of pollutants of emerging concern in the aquatic environment. Though present in trace concentrations, these pollutants are highly eco-toxic and...

Microbial fuel cells (MFCs) have been the prime focus of research in recent years because of their distinctive feature of concomitantly treating and producing electricity from wastewater. Nevertheless, the electrical performance of MFCs is hindered by a protracted oxygen reduction reaction (ORR), and often a catalyst is required to boost the cathod...

Anaerobic digestion is a well versed technology for treating organic waste and converting the organic matter into biogas to be subsequently used as fuel or converted into electricity. Over the years, anaerobic digestion has been widely used for the treatment of industrial and domestic wastewaters as well as organic solid waste, while simultaneously...

Microbial fuel cell (MFC) is an upcoming technique for the treatment of wastewater while simultaneously producing electricity.
