Conditioning of raw sludge and thermally hydrolyzed sludge by ferric salt and cationic polyacrylamide: rheological analysis

Water Science and Technology, 2021
In this study, the conditioning effect of cationic polyacrylamide (CPAM) with different charge densities on raw sludge (RS) and thermo-hydrolyzed sludge (HS) pretreated with or without ferric salt is studied through orthogonal experiments.

Antimicrobial Resistance of Serratia marcescens Recovered From Aquatic Environments: A Review

Environmental Microbiology Reports, Volume 18, Issue 4, August 2026.
Serratia marcescens is a gram‐negative bacillus forming biofilms and showing multidrug resistance. Review (2019–2024) included 13 studies, 90 aquatic isolates. High resistance to β‐lactams, including carbapenems. Genes: blaOXA‐48, blaTEM‐1, aac(6′)‐Ic. Aquatic environments are reservoirs, requiring monitoring and control to prevent spread.

Moderate‐Temperature Hydrothermal Treatment Removes Detectable DNA and Antibiotic Resistance Genes From Municipal Sludge While Preserving Resource Value

Water and Environment Journal, Volume 40, Issue 3, Page 484-494, August 2026.
This graphical abstract shows the overall study design where dewatered wastewater sludge samples were collected and subjected to a range of HT temperatures. Measurement of nucleic acid concentration and antibiotic resistance gene profiles across temperatures showed that HT at moderate temperatures offers sustainable, scalable sludge sanitation and ARG ...

Struvite Production From Wastewater: Effect of Magnesium‐to‐Ammonia Ratio and Stirring Velocity on Precipitation Efficiency and Settling Behavior

CLEAN – Soil, Air, Water, Volume 54, Issue 7, July 2026.
This study demonstrates that stoichiometric Mg2+:PO43− excess (1.1:1) and slow 10‐min dosing are critical for maintaining low supersaturation, yielding large crystals (>0.84 mm) and rapid settling (5.5–10.1 cm/min). This strategy optimizes nutrient recovery (≥80%) and solid–liquid separation without flocculants, proving viable for complex industrial ...

Exergy‐Based Simulation and Optimization of Multiagent MSW Gasification for Sustainable Energy Recovery Using Aspen Plus

Energy Science &Engineering, Volume 14, Issue 7, Page 3118-3131, July 2026.
ABSTRACT Thermochemical gasification is one of the most efficient methods for producing solid waste synthesis gas. Therefore, to predict and analyze the process of gasification of municipal solid waste (MSW) in a downdraft fixed‐bed gasification reactor with a thermal capacity of 2.1 kW, a comprehensive numerical modeling approach based on Gibbs free ...

Sewage sludge application on agricultural soils in Wallonia: Long‐term monitoring and impact assessment of practices

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract In the context of sustainable agriculture and circular resource management, the use of wastewater treatment plant secondary sludge in agriculture represents an interesting opportunity. Its use is strictly regulated to guarantee environmental and food safety through analysis of both sludge and soils on which it was spread.

Waste activated sludge high‐rate treatment of septage: Biodegradability studies and contact phase trials towards a cleaner environment

The Canadian Journal of Chemical Engineering, Volume 104, Issue 6, Page 2842-2861, June 2026.
Abstract The waste activated sludge high‐rate (WASHR) process, developed in our previous study, is used for septic wastewater treatment. This high‐rate contact stabilization pre‐treatment uses typical waste streams found in wastewater treatment plants to reduce a portion of the loadings on the main treatment trains.
