The Effects of Aluminium- and Ferric-Based Chemical Phosphorus Removal on Activated Sludge Digestibility and Dewaterability [PDF]

open access: yes, 2019
The uses of Al3+ and Fe3+ salts in chemical phosphorus removal (CPR) in activated sludge plants have increased considerably in recent years and their full impacts on downstream processes such as dewaterability and digestibility are not fully understood ...

Application of Principal Component Analysis and Probabilistic Neural Networks in Ferralsols Recovery Evaluation Through Planting of Mabea Fistulifera and Eucalyptus Urograndis

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT This study presents an innovative assessment model for analyzing the evolution of degraded soils subjected to different reclamation strategies. The proposal combines statistical and artificial intelligence tools to jointly integrate multiple physical and chemical soil properties, allowing for a more synthetic view of the processes.

Potential of activated sludge ozonation

open access: yesWater 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.

Sludge Production and Disposal for Small Cold Climate Bio-Treatment Plants [PDF]

open access: yes, 1972
Ultimate disposal of wastewater sludge has long been a problem which to a large degree has been ignored. Haney (1971) stated that: "Until process sludge can be handled with minimum environmental impact, we cannot claim to have a viable wastewater ...

Toxicity of Chromium to Activated Sludge

open access: yesEcotoxicology and Environmental Safety, 1999
The work deals with the toxicity of hexavalent and trivalent chromium to activated sludge. Cr(VI) was added as K2Cr2O7, and Cr(III) as Cr2(SO4)3. Toxicity is expressed as the inhibition of respiratory activity of microorganisms present in activated sludge.

Integrating Business Process Management With the Sustainable Development Goals: A Multidimensional Framework for Systemic Sustainability

open access: yesSustainable Development, EarlyView.
ABSTRACT This study proposes a multidimensional framework to integrate Business Process Management (BPM) with the Sustainable Development Goals (SDGs), addressing gaps in research and practice. Through a bibliometric science mapping using keyword co‐occurrence network analysis in VOSviewer (Scopus 2015–2024), we identify five thematic clusters ...
