Remediation of Organic Pollutant for Wastewater Treatment by Employing Sustainable Graphene Oxide/NiO‐ZrO2/Zeolite Ternary Composite Material

CleanMat, EarlyView.
Graphene oxide/NiO‐ZrO2/zeolite ternary composite was synthesized hydrothermally. Efficient adsorption of Congo red onto GO/NiO‐ZrO2/zeolite composite was studied. ABSTRACT The present study employs a novel method for the synthesis of graphene oxide (GO) based ternary composite utilized for the adsorption of Congo red (CR), an anionic dye molecule. The

Enhancement of the Plant‐Accessible Phosphate Fraction in Sewage Sludge Ashes by Na+ or K+ Addition Prior to Combustion

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The addition of Na2CO3 or K2CO3 to sewage sludge prior to combustion leads to the production of ashes containing phosphate in the form of buchwaldite‐like phases (Ca(Na/K)PO4). Compared to conventional sewage sludge mono‐ashes, such Na‐ or K‐ashes show greatly increased P‐solubilities and proved to be potent P‐fertiliser materials in greenhouse ...

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 ...

Light‐Induced Structural Reorganization of Fe Centers Unlocks High Efficiency of Visible‐Light Photo‐Fenton Water Cleaning Catalyst

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Bimetallic Cu and Fe oxide species supported on porous silica with interparticle mesoporosity act as efficient photo‐Fenton‐like catalysts under visible light. Photogenerated electrons drive the Cu2+/Cu1+ redox cycle. Part of Cu1+ is responsible for the regeneration of the Fe3+/Fe2+ cycle at neutral pH. Light irradiation additionally induces structural

Detection of salmonella in composted wastewater sludge: a report on a research project carried out for the Water Authority of Western Australia [PDF]

, 1995
It is likely that Australian sludge management guidelines will require monitoring of composted wastewater sludge for the presence of salmonellae. However, methods to perform this monitoring are not well established and it appears that methods used in the

Tuning Cation Disorder in LiNi0.5Mn1.5O4 via Room Temperature Continuous‐Flow Co‐Precipitation and Controlled Heat Treatment

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
LiNi0.5Mn1.5O4 (LNMO) precursors were produced at room temperature by Ambient Continuous Turbulent In‐line Mixing (ACTIM) at rates of up to 0.42 kg h−1. The final heat treatment step at 650, 700, or 750 °C, altered cation disorder and the electrochemical behavior of the LNMO cathodes, while the effect of adding MWCNTs to the electrodes, was also ...

Challenges in Implementing European Regulation on Water Reuse for Sustainable Agriculture

Environmental Policy and Governance, EarlyView.
ABSTRACT The Regulation (EU) 2020/741 on minimum requirements for water reuse is a key policy for sustainable water management under growing water scarcity in Europe. This paper examines expert perspectives on the challenges involved in implementing EU regulation for water reuse in agriculture, aiming to broaden existing research, which is largely ...
