Abstract Nitrate (NO 3−) pollution in water and wastewater has become a serious global
issue. Biological denitrification, which reduces NO 3− to N 2 (nitrogen gas) by denitrifying …

Adsorption is a very promising and efficient technology for the removal of hazardous
pollutants from water. In this regard, clay minerals have gained prime importance because of …

Sanitation is the basic quality index of life and proper sanitation practices play a vital role in
maintaining the hygienic conditions. Use of human waste (urine and faeces) as a substrate …

Simultaneous power generation and nitrogen and carbon removal were achieved in a single-
chamber microbial fuel cell for high-salinity mustard tuber wastewater treatment. The results …

Petroleum industries are large water consumers and generate a lot of wastewater at various
stages of industrial operations. Wastewater from the petroleum industries contain recalcitrant …

The extracellular electron transfer (EET) efficiency in bioelectrochemical systems has been
proven to be dependent on anode potentials. To explore the underlying mechanism …

Lack of suitable electron donors or acceptors is in many cases the key reason for pollutants
to persist in the environment. Externally supplementation of electron donors or acceptors is …

Biochar is widely used in water treatment because of its porous structure, however, the
effects of biochars on denitrification remain unclear. Here, we combined molecular …

The pollution of nitrate (NO 3-) in groundwater has become an environmental problem of
general concern and requires immediate remediation because of adverse human and …

Nitrate removal from low carbon-to-nitrogen ratio (C/N) wastewater has always been a knotty
problem due to the deficiency of organics. Here, a novel iron-based chemical reduction and …
