Multi-omics analysis reveals structure and function of biofilm microbial communities in a pre-denitrification biofilter.

Science of the Total Environment, 2020
The highly complex microbial communities in biofilm play crucial roles in the pollutant removal performance of wastewater treatment plants (WWTPs). In the present study, using multi-omics analysis, we studied microbial structure, key enzymes, functional ...

The impact of stormwater biofilter design and operational variables on nutrient removal - a statistical modelling approach.

Water Research, 2020
Biofiltration systems can help mitigate the impact of urban runoff as they can treat, retain and attenuate stormwater. It is important to select the optimal design characteristics of biofilters (e.g., vegetation, filter media depth) to ensure high ...

Influence of temperature on CODMn and Mn2+ removal and microbial community structure in pilot-scale biofilter.

Bioresource Technology, 2020
Test water temperature (TWT) is a significant operational parameter in biofilter. In this study, a pilot-scale biofilter was established to investigate the removal efficiency of CODMn and Mn2+ and the microbial community structure at different TWT.

Toluene Removal Biofilter Modeling

Journal of the Air & Waste Management Association, 2008
On the basis of the model proposed by De Visscher and Van Cleemput for methane oxidation in landfill cover soils, simulation models for biofiltration of toluene-contaminated air were performed for biofilters with or without substrate inhibition and operated at constant or varying airflow rates. The toluene oxidizing activity (V(max)) expressions of the

Performance enhancement of a biofilter with pH buffering and filter bed supporting material in removal of chlorobenzene.

Chemosphere, 2020
Acidic substances, which produced during chlorinated volatile organic compounds, will corrode the commonly used packing materials, and then affect the removal performance of biofiltration.

Spatial denitrification performance and microbial community composition in an up-flow immobilized biofilter for nitrate micro-polluted water treatment

, 2020
Nitrates in secondary effluent need further removal to ensure water quality and protect the aquatic ecosystem. A lab-scale continuous up-flow immobilized biofilter (I–BF) (15L) based on polyurethane foams (PUFs) carriers immobilized bacterial consortia ...

Moisture in biofilters

Environmental Progress, 1999
AbstractWater availability is a major determinant of pollutant degradation rates by microbes in biofilters. Water content is an indirect index of availability because much water in organic biofilter media is bound too tightly in the particles to be available for microbial metabolism. Available water is primarily in the contacts between particles.

Single-stage denitrifying phosphorus removal biofilter utilizing intracellular carbon source for advanced nutrient removal and phosphorus recovery.

Bioresource Technology, 2019
Advanced nutrient removal of municipal wastewater has insufficient carbon source, and resource recovery is neglected. In this study, a single-stage biofilter based on denitrifying phosphorus removal (DPR) was proposed for advanced nutrient removal and ...
