Is building up substrate during anaerobic feeding necessary for granulation?

Water Science and Technology, 2022
For a successful granulation process in activated sludge systems, the stimulation of slow growing organisms such as glycogen accumulating microorganisms (GAOs) is a key factor.

Critical mineral removal from mining‐impacted waters using microalgal biomass

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Rising demand for critical minerals has led to increased mining and mineral processing activities, resulting in the release of metal‐contaminated waters requiring treatment. Conventional treatment methods, such as lime neutralization, effectively precipitate metals; however, they are less effective at low metal concentrations and produce large

Iron‐modified natural sand as a heterogeneous Fenton catalyst for methylene blue and textile wastewater treatment

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND The continuous discharge of organic dyes into freshwater poses long‐term environmental risks. Heterogeneous Fenton‐like processes using iron (Fe)‐modified silica (SiO2) supports are promising for dye removal; however, catalysts derived from natural sand and operating under near‐neutral conditions remain relatively underexplored ...

One Hundred Years of the German Soil Science Society (DBG) 1926–2026: Origins, Facts, and Background of an Eventful History

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT On its 100th anniversary in 2026, the German Soil Science Society (DBG) is looking back not only on an eventful history with traditions and impressive achievements but also with painful interruptions and ruptures. One curious fact is that the DBG was initially founded as the national section of the International Soil Science Society (ISSS ...

Regulation of aerobic granular sludge reformulation after granular sludge broken: Effect of poly aluminum chloride (PAC)

, 2014
The present study focuses on the effect of poly aluminum chloride (PAC) on the re-formation of aerobic granular sludge after its rupture. The morphological changes, physical characteristics such as SVI, mechanical strength and surface properties of ...

Plant Availability of Phosphorus From Sewage Sludge Ash‐Based Fertilizers and Its Relationship to Phosphorus Extractability

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Sewage sludge ash (SSA) is a potential phosphorus (P) source for fertilizers, but untreated SSA (USSA) often shows low plant availability of P. To increase P availability, sodium additives can be applied before sewage sludge incineration or during thermochemical SSA posttreatment, as this leads to the formation of CaNaPO4.

Bio‐Derived Carbon Nanoparticles: A Green Amendment for Alleviating Heavy Metals in Soil–Plant Systems

Land Degradation &Development, EarlyView.
ABSTRACT Heavy metal (HM) contamination of soil–plant systems poses persistent ecological and health risks, driving interest in nanoparticle‐based remediation. Although conventional chemically synthesized nanoparticles (CSNPs) are effective, their energy‐intensive production and residual toxicity limit sustainable deployment.
