Exploring the potential of biofiltration for mitigating harmful gaseous emissions from small or old landfills: a review.

Landfills are widely employed as the primary means of solid waste disposal. However, this practice generates landfill gas (LFG) which contains methane (CH), a potent greenhouse gas, as well as various volatile organic compounds and volatile inorganic compounds. These emissions from landfills contribute to approximately 25% of the total atmospheric CH, indicating the imperative need to valorize or treat LFG prior to its release into the atmosphere.

Prolonged operation of a methane biofilter from acclimation to the failure stage.

Global warming needs immediate attention to reduce major greenhouse gas emissions such as methane (CH). Bio-oxidation of dilute CH emissions in packed-bed bioreactors such as biofilters has been carried out over recent years at laboratory and large scales. However, a big challenge is to keep CH biofilters running for a long period.

Air biofilters for a mixture of organic gaseous pollutants: an approach for industrial applications.

Hazardous airborne pollutants are frequently emitted to the atmosphere in the form of a gaseous mixture. Air biofilters as the primary biotechnological choice for waste gas treatment (low inlet concentration and high gas flow rate) should run properly when the feed contains multiple pollutants. Simultaneous removal of pollutants in biofilters has been extensively studied over the last 10 years.

Efficiency of an up-flow Anaerobic Sludge Blanket reactor coupled with an electrochemical system to remove chloramphenicol in swine wastewater.

The application and design of treatment systems in wastewater are necessary due to antibiotics' potential toxicity and resistant genes on residual effluent. This work evaluated a coupled bio-electrochemical system to reduce chloramphenicol (CAP) and chemical oxygen demand (COD) on swine wastewater (SWW). SWW characterization found CAP of <10 μg/L and 17,434 mg/L of COD.

Bioelimination of low methane concentrations emitted from wastewater treatment plants: a review.

Sewage from residents and industries is collected and transported to wastewater treatment plants (WWTPs) with sewer networks. The operation of WWTPs results in emissions of greenhouse gases, such as methane (CH), mostly due to sludge anaerobic digestion. Amounts of emissions depend on the source of influent, i.
