Effect of ammonium concentration on methane oxidation and CO2 removal in an anaerobic biotrickling filter treating synthetic landfill gas and leachate

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Landfill gas (LFG) and leachate are commonly treated separately through energy‐intensive processes. This study evaluated the integration of both streams in an anaerobic biotrickling filter (BTF) to achieve simultaneous methane (CH4) and carbon dioxide (CO2) removal coupled with ammonium (NH4+) transformation, and how the microbial ...

Modelling of a biofiltration process of volatile organic compound mixtures in a biofilter

Biotechnology & Biotechnological Equipment, 2016
Currently, different methods for air clean-up from chemical pollutants are applied worldwide: adsorption, absorption, and thermal and catalytic oxidation. One of the most promising methods is biological air cleaning. The aim of this study was to test the

An investigation into the performance of vegetated biofilters in removing nutrients from stormwater in the City of Cape Town, South Africa [PDF]

, 2011
In 2009, the City of Cape Town (CoCT) adopted a stormwater policy which mandates that new and existing developments should reduce the concentrations of phosphorus and suspended solids in stormwater runoff by 45% and 80% respectively, but offered no ...

Polyhydroxybutyrate (PHB) From Biofloc Systems Enhances the Growth and Immune Performance of Genetically Improved Farmed Tilapia

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT This study characterised polyhydroxybutyrate (PHB)‐producing bacteria from the culture water of genetically improved farmed tilapia (GIFT) in biofloc ponds and investigated the influence of PHB on the growth and immune performance of GIFT. Out of 40 bacterial isolates, Bacillus infantis, Exiguobacterium profundum, Bacillus subtilis, Bacillus ...

Distribution, scale, and drivers of mass mortality events in Europe's freshwater bivalves

Conservation Biology, Volume 40, Issue 2, April 2026.
Abstract Mass mortality events (MMEs) are decimating populations and compromising key ecosystem functions around the globe. One taxon particularly vulnerable to MMEs is freshwater bivalve mollusks. This group has important ecosystem engineering capacities and includes highly threatened and highly invasive taxa.

Temporary storage or permanent removal? The division of nitrogen between biotic assimilation and denitrification in stormwater biofiltration systems. [PDF]

PLoS ONE, 2014
The long-term efficacy of stormwater treatment systems requires continuous pollutant removal without substantial re-release. Hence, the division of incoming pollutants between temporary and permanent removal pathways is fundamental.

Study of seawater biofiltration by measuring adenosine triphosphate (ATP) and turbidity [PDF]

, 2013
In the present study, we examined seawater biofiltration in terms of adenosine triphosphate (ATP) and turbidity. A pilot biofilter continuously fed with fresh seawater reduced both turbidity and biological activity measured by ATP.
