Kinetic study of palm oil mill effluent (POME) treatment by activated sludge [PDF]

, 2019
Kinetic parameter is a basis for design and optimization of activated sludge POME treatment. In fact, most of the kinetic parameter value used in design and optimization are default values taken from municipal wastewater.

Potential of activated sludge ozonation

Water Science and Technology, 2007
The disposal of sewage sludge and the agricultural use of stabilised sludge are decreasing due to more stringent regulations in Europe. An increasing fraction of sewage sludge must therefore be dewatered, dried, incinerated and the ashes disposed of in landfills.

Antarctic soil microbiomes encode structurally conserved and phylogenetically diverse beta‐lactamases

iMetaOmics, EarlyView.
An integrative metagenomic framework combining sequence, structural, and functional inference reveals a phylogenetically diverse and structurally conserved repertoire of putative beta‐lactamases across Antarctic soil microbiomes, with predominance of class A and subclass B3 enzymes and limited but detectable associations with mobile genetic elements ...

Antiviral defense systems drive persistence of antimicrobial‐resistant bacteria but limit the transfer of antimicrobial resistance genes in anaerobic digestion

iMeta, EarlyView.
Phage–host interactions critically shape environmental antimicrobial resistance (AMR). Using swine manure anaerobic digestion and multi‐omics (metagenomics, meta‐transcriptomics, and Hi‐C), we mapped the phage–bacteria arms race and its impact on AMR dynamics.

On an application of extended kalman filtering to activated sludge processes: a benchmark study

, 2005
The growing demand for performance improvements of urban wastewater system operation coupled with the lack of instrumentation in most wastewater treatment plants motivates the need for non-linear observers to be used as virtual sensors for estimation and
