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

Enhanced Electro-Dewatering of Sludge Through Inorganic Coagulant Pre-Conditioning
SeparationsSludge electro-dewatering technology is an attractive dewatering technology, but its application is limited by high energy consumption and filter cloth clogging caused by the dissolution of extracellular polymeric substances (EPSs). Thus, the addition of

Clogmia albipunctata Larvae Influence the Odour Dynamics of Rotting Organic Matter
Entomologia Experimentalis et Applicata, EarlyView.Drain flies live in organic waste. We investigated how drain fly larvae influence the unpleasant smells produced by sewage sludge and rotting nettle. Although the perception of these smells did not change significantly according to the public, chemical analyses showed that sewage sludge with drain fly larvae yielded a different composition of odors ...

Tunable amylopectin graft copolymers for flocculating and dewatering iron ore tailings
The 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 =
