Carbon‐Negative Upcycling of Sewage Sludge into Superiorly Stable Gel Via Liquid‐Phase Utilization Strategy for Water‐Remediation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work developed a low‐temperature sludge hydrothermal coupled with gel crosslinking strategy which could upgrade the waste liquid generated from sewage sludge hydrothermal treatment into the hydrothermal‐liquid‐gel. The inventive hydrothermal‐liquid‐gel exhibited the enhanced pollutant removal capability, high synthetic stability, and superior ...

Waste to Hydrogen: Transforming Food Waste Into Biohythane (Bio‐H2 + Bio‐CH4) in a Two‐Stage Reactor With the Aid of a Metal‐Ion Catalyst

Energy Science &Engineering, EarlyView.
This study demonstrates a two‐stage catalytic bioreactor system that converts real food waste into high‐purity biohydrogen and biohythane. In Stage‐1, an enriched Clostridium thermocellum culture combined with Ni2+─Fe2+ bimetallic catalysis enhances hydrolysis efficiency and hydrogenase activity, resulting in a 77% increase in H2 yield and 75.8% purity

On‐site pilot‐scale advanced oxidation pretreatment of hospital wastewater: assessment of pharmaceuticals, pathogens, antibiotic resistance genes and acute ecotoxicity

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Hospital premises generate wastewater containing a wide spectrum of contaminants, such as pharmaceutically active compounds (PhACs), antibiotic resistance genes (ARGs) and pathogenic microorganisms, whilst plenty of them are classified under the antibiotic resistant bacteria (ΑRΒ) category.

The Sludge Dewaterability in Advanced Wastewater Treatment: A Survey of Four Different Membrane BioReactor Pilot Plants [PDF]

, 2017
The wasted activated sludge dewaterability represents a major concern for Wastewater Treatment Plants (WWTPs) managers. Indeed, whereas the dewatered sludge could represents a re-usable matrix, the principal drawback related to the wasted sludge ...

The use of activated carbon derived from spent coffee grounds as a reusable, sustainable, and effective solution for the removal of butylparaben from water

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Parabens, including butylparaben (BP), are widely used as antimicrobial preservatives in food, cosmetics, and pharmaceuticals, yet are poorly removed by conventional water treatment processes and pose potential risks to aquatic life and human health.

Effect of ammonium concentration on methane oxidation and CO2 removal in an anaerobic biotrickling filter treating synthetic landfill gas and leachate

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Landfill gas (LFG) and leachate are commonly treated separately through energy‐intensive processes. This study evaluated the integration of both streams in an anaerobic biotrickling filter (BTF) to achieve simultaneous methane (CH4) and carbon dioxide (CO2) removal coupled with ammonium (NH4+) transformation, and how the microbial ...
