A Facile Salt‐Assisted Dewatering for Carboxymethyl Cellulose‐Based Hydrogels
Polymer Engineering &Science, EarlyView.Dehydration efficiency of hydrogels increases with NaCl concentration during washing. ABSTRACT Natural polymer‐based hydrogels are gaining attention as an environmentally friendly alternative to petroleum‐based superabsorbent polymers. The hydrogel fabrication process involves washing and drying hydrated gels. However, due to their high hydrophilicity,

Experimental Study on Fine Sediment Infiltration (FSI) Processes in Different Gravel Mixtures
River Research and Applications, EarlyView.ABSTRACT Fine sediment infiltration (FSI) can lead to riverbed clogging, thereby degrading important habitats for aquatic biota in the hyporheic interstitial zone of gravel‐bed rivers (e.g., by reducing oxygen availability). This stress on rivers may increase from anthropogenic influences and can be counteracted by artificial gravel augmentation to ...

Dewatering and Structural Analysis of Foam-Formed, Lightweight Fibrous Materials
BioResources, 2022 This work studied the effect of the dewatering conditions on the behavior of fiber foams during dewatering and on the final structure of the formed, thick, lightweight lignocellulosic materials. The vacuum level, fiber type, consistency, and basis weight

Environmental Toxicology, EarlyView.ABSTRACT This study assessed the ecotoxicological effects of treated sewage on the freshwater planarian Girardia tigrina, integrating biochemical, energetic, and behavioral biomarkers. Planarians were exposed for 48 h to different concentrations of treated sewage (12.5%, 25%, 50%, and 100%) and compared to controls using commercial water and water from

Effects of acid-heat combined treatment on sludge dewatering performance at low temperature [PDF]
E3S Web of Conferences, 2019 The effects of different initial pH value, temperature and heating time on sludge dewatering performance were studied by treating sludge with acid-heat combination at low temperature and taking dewatering rate (amount of filtrate per unit time) and ...

Boreas, EarlyView.Understanding the course and dynamics of ancient river systems, such as the pre‐Odra, provides valuable insights into the post‐glacial evolution of landscapes and riverine processes. The northwest‐trending pre‐Odra was an important drainage system of the European mainland into the Baltic Basin during and after the Scandinavian Ice Sheet retreat ...

Boreas, EarlyView.Map of Lower sediment (LS) thickness is a surrogate for the distribution of Thorncliffe Formation (TF) and ~75% of TF thickness from the slope of Niagara Escarpment east to Brighton. Inset images show the LS sequence at the Don Valleys brickyards (DVBY) and undeformed TF sand and gravel (~15 m) below Newmarket Till (NT) at sites L and Co.
