Dewatering and valorizing lake sediments by electroosmotic dewatering for lakes restoration

open access: yesEnvironmental Science and Pollution Research
Abstract Dredging eutrophic lake sediments can improve water quality, but it also requires dewatering and valorizing the dredged material to avoid wasting resources like phosphorus. This study experimentally investigated the basic mechanism and performance of electroosmotic dewatering of 1-L dredged sediments ...

Outcrop and subsurface characterisation of a mixed tidal and wave‐influenced coastline (Triassic Red Beds, SE Spain)

open access: yesSedimentology, EarlyView.
ABSTRACT Paralic depositional systems are complex and heterogeneous sedimentary environments, presenting challenges for predicting reservoir architecture and connectivity. Their stratigraphic and facies variability arises from the dynamic interplay between fluvial, tidal and wave processes, and their sensitivity to sea‐level fluctuations, sediment ...

A Triassic chronostratigraphic and palaeogeographic framework for the Utsira High area, northern North Sea: Reconstructing a basin‐scale drainage divide

open access: yesSedimentology, EarlyView.
ABSTRACT The Triassic succession of the northern North Sea comprises a series of interbedded sandstones, mudstones and conglomerates deposited under a fluctuating arid to semi‐humid climate regime, which are often difficult to correlate regionally due to differing lithostratigraphic schemes and poor age control. Despite existing regional studies on the

Evaluating Oxygen Demand in Mainstream Anammox, A2O and Partial Denitrification/Anammox (PD/A) Processes: A Gradient‐Based Sensitivity Analysis

open access: yesWater and Environment Journal, EarlyView.
This graphical abstract illustrates the oxygen demand reduction potential of the mainstream anammox process compared to conventional A2O and PD/A processes. It visually demonstrates maximum oxygen savings of 28.25% and 18.58%, respectively, under optimal conditions.

SiC/Si ceramic hollow fibres: A new approach to Chlorella vulgaris biomass harvesting

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 9, Page 4568-4578, September 2026.
Abstract Efficient harvesting of microalgae is a critical challenge for the viability of biorefineries, requiring technologies that combine high selectivity, low cost, and scalability. The current work evaluated the performance of an asymmetric hollow fibre ceramic membrane (HF‐SiC70Si30), fabricated by phase inversion and sintered at 1250°C, in the ...

Research progress on engineering applications of flocculation conditioning to enhance the dewatering and consolidation of dredged sediment

open access: yesGongye shui chuli
The treatment, disposal, and resource utilization of dredged sediments are facing challenges in current dredging projects, while achieving effective dewatering and consolidation of sediments is a necessary prerequisite for solving this problem.

Tunable amylopectin graft copolymers for flocculating and dewatering iron ore tailings

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 9, Page 4597-4612, September 2026.
Abstract Polyacrylamide (PAM), the standard flocculant for mining tailings, often produces turbid supernatants and poorly dewatered sediments, limiting water reuse and tailings densification. We synthesized amylopectin‐graft‐poly[(2‐methacryloyloxy)ethyl]trimethylammonium chloride (AP‐g‐PMETAC) copolymers with systematically varied graft frequency (N =

A Generalized Predictive Model for Displacement Washing of Partially Reslurried Filter Cakes

open access: yesChemical Engineering &Technology, Volume 49, Issue 8, August 2026.
During displacement washing, partial reslurrying of the filter cake surface frequently occurs as an undesired side effect of wash liquid application, causing premature contamination of the wash liquid through mixing with cake impurities. This contamination can limit both washing efficiency and the achievable washing result.

Redistribution of Sediment and Particulate Mercury Within Upstream Reaches of Galveston Bay in Response to Hurricane Harvey

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Extreme storms and flooding can remobilize legacy contaminants stored in the sediment bed; however, event‐scale models that resolve the transport of these materials remain underdeveloped. This study developed a numerical model of contaminated sediment transport during Hurricane Harvey (August 2017), which struck the upstream reaches of ...
