Location and chemical composition of microbially induced phosphorus precipitates in anaerobic and aerobic granular sludge [PDF]

, 2012
This work focuses on combined scanning electron microscopy and energy dispersive X-ray analysis (SEM-EDX) applied to granular sludge used for biological treatment of high-strength wastewater effluents. Mineral precipitation is shown to occur in the core

Physico-mechanical and microstructural behaviour of high-water-content dredged sediment treated by vacuum preloading coupled with alkali-activated materials

Case Studies in Construction Materials
High-water-content dredged sediment (HWDS) solidification via the physico-chemical combination method (PCCM) shows potential for land reclamation. Traditional cement-lime-based PCCM demonstrates limitations of high cost and carbon emissions. Fly ash (FA),

Synergistic Advanced Oxidation and Physicochemical Treatment Strategies for Antibiotic Removal and Resistance Mitigation in Water

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The presence of antibiotics in water not only causes environmental pollution but also increases the growth of antibiotic‐resistant bacterial genes, which pose serious threats to human beings and other water residents. Large numbers of people are reportedly affected by the resistant bacterial genes, as many broad‐spectrum antibiotics are not ...

Coupling effect of cement-stabilization and biopolymer-modification on the mechanical behavior of dredged sediment

Journal of Rock Mechanics and Geotechnical Engineering
Nowadays, biopolymer stabilization as a promising eco-friendly approach in soft ground improvement has attracted wide attentions. However, the feasibility of using biopolymer as a green additive of cement-stabilized dredged sediment (CDS) with high water

A Holistic and Experimentally-Based View on Recycling of Off-Gas Dust within the Integrated Steel Plant

Metals, 2018
Ore-based ironmaking generates a variety of residues, including slags and fines such as dust and sludges. Recycling of these residues within the integrated steel plant or in other applications is essential from a raw-material efficiency perspective.

Evaluation of Greenhouse Gas Emissions and Sludge Characteristics in Typical AAO Process WWTPs in Taihu Lake Basin, China

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study investigated sludge characteristics and greenhouse gas (GHG) emission from 16 anaerobic‐anoxic‐oxic (AAO) process wastewater treatment plants (WWTPs), 11 municipal and 5 industrial WWTPs, located in the Taihu Lake Basin, China. Influent/effluent water quality, sludge properties, operational parameters, GHG emission patterns, and ...
