The production and management of sludge in wastewater treatment plants is a significant
environmental issue. Sludge is a complex material, treated primarily by biological …

Sludge reduction via microbial metabolism does not require extra energy and resource
inputs and thus merits attention as an alternative approach for sustainable wastewater …

The aim of this work was to study the effect of thermal alkaline pretreatment and zinc acetate-
catalyzed methanolysis (MtOH-ZnOAc) in biogas production from bioplastic in anaerobic …

The eutrophication of water bodies caused by the release of treated wastewater rich in total
phosphorus (TP) is a worldwide problem. In this work a full-scale wastewater treatment plant …

An energy-/cost-efficient and environment-friendly in-situ sludge reduction process, called
the sulfidogenic oxic-settling anaerobic (SOSA) was developed recently. However, the …

On-site minimization of excess sludge production is a relevant strategy for the operation of
small-scale and decentralized wastewater treatment plants. In the study, we evaluated the …

In-situ sludge reduction can be achieved by inserting an anaerobic side-stream reactor in
the sludge return line of the conventional activated sludge (CAS) process. This modified oxic …

Among the existing in-situ sludge reduction processes, the oxic-settling-anaerobic (OSA)
process is of particular interest because it has shown significant sludge reduction with …

We designed novel quantitative real-time polymerase chain reaction (qPCR) primers for the
polyphosphate kinase 1 (ppk1) gene, targeting eight individual “Candidatus …

An advanced side-stream reactor process with alkaline treatment (SIPER) has been
demonstrated excellent sludge reduction potential and nutrient removal in the previous pilot …
