Granulation in UASB Reactors

open access: yesWater Science and Technology, 1986
The state of knowledge on the microbiological aspects of granular methanogenic sludge in upflow anaerobic sludge blanket (UASB) reactors is reviewed. Granular methanogenic sludge has been observed in a variety of upflow reactors, which is in agreement with the hypothesis that these systems select for well settling sludges. In methanogenic UASB reactors

Sulfide toxicity kinetics of a uasb reactor [PDF]

open access: yesBrazilian Journal of Chemical Engineering, 2009
The effect of sulfide toxicity on kinetic parameters of anaerobic organic matter removal in a UASB (up-flow anaerobic sludge blanket) reactor is presented. Two lab-scale UASB reactors (10.5 L) were operated continuously during 12 months. The reactors were fed with synthetic wastes prepared daily using glucose, ammonium acetate, methanol and nutrient ...

Influence of pulsation on start-up of UASB reactors

open access: yesWater Science and Technology, 2002
The aim of this work is to study the influence of pulsation on the start-up of lab-scale UASB reactors. Pulsation was produced by an Elastic Membrane Pulsator (EMP). The application of this device in previous works improved the performance of continuous fixed-bed fermentors and reduced the formation of preferential pathways, the retention of gas ...

High-rate dark fermentative hydrogen production in a UASB reactor with granular activated carbon and Clostridium pasteurianum bioaugmentation

open access: yesFrontiers in Microbiology
The combined application of granular activated carbon (GAC) and Clostridium pasteurianum bioaugmentation was evaluated in an up-flow anaerobic sludge blanket (UASB) reactor for high-rate dark fermentative hydrogen production under progressively shortened

How AI and Digital Technologies Can Enhance Sustainable Livestock Manure Management: An Overview From Treatment to Distribution

open access: yesSustainable Development, EarlyView.
ABSTRACT Sustainable livestock manure management sits at the nexus of climate, nutrient circularity and water quality. This review explores how artificial intelligence (AI) and digital platforms are used across four management stages, that is, treatment, storage, valorisation and distribution, and figures out where integration fails to deliver ...

Biochar‐Induced Shifts in Fungal Community Structure and Their Association With Soil Physical Properties in Degraded Soil From the Brazilian Semiarid

open access: yesLand Degradation &Development, Volume 37, Issue 13, Page 9067-9083, 15 August 2026.
ABSTRACT Soil degradation compromises ecosystem functioning. Biochar, a carbon‐rich amendment, has gained attention as a promising strategy to enhance soil structure and restore microbial balance. This study investigated the effects of two biochars, cashew bagasse biochar (CBB) and a co‐pyrolyzed biochar produced from sewage sludge and cashew pruning ...

Enhancement of overloaded waste stabilization ponds using different pretreatment technologies: a comparative study from Namibia

open access: yesJournal of Water Reuse and Desalination, 2020
Waste stabilization ponds (WSP) are a well-established wastewater treatment technology in Namibia. However, they are often overloaded and we still lack concepts and technologies for improvement.
