Chemical Engineering Journal, Год журнала: 2024, Номер 486, С. 150260 - 150260

Опубликована: Март 8, 2024

Anaerobic membrane bioreactors hold immense promise for wastewater treatment owing to their elevated organic load tolerance, cost-effectiveness, and potential energy recovery. Nevertheless, fouling is a significant impediment its widespread implementation. This review focuses on utilizing eco-friendly bioflocculants control in anaerobic bioreactors. Initially, it provides comprehensive overview of the mechanisms mitigating fouling. Subsequently, examines performance, mechanisms, influencing factors reducing by AnMBRs. Charge density, molecular weight, bioflocculant dosage, feed water properties, operational parameters can affect efficacy. The primary mechanism helpful reduce concentrations Extracellular Polymeric Substances (EPS) Soluble Microbial Products (SMP) Additionally, conventional methods are introduced compared with bioflocculants, emphasizing notable advantages, such as biodegradability, low toxicity, availability, cost-effectiveness. In conclusion, outlines challenges associated elucidates directions future development.

Residue-Free and Recyclable Starch-Based Flocculants for Dye Wastewater Flocculation

Langmuir, Год журнала: 2024, Номер 40(6), С. 3231 - 3240

Опубликована: Фев. 1, 2024

Flocculants are crucial agents in wastewater treatment because they can remove oppositely charged impurities effectively and swiftly. However, flocculation also inevitably causes secondary contamination due to the residual properties, nonreusability, nondegradability of traditional flocculant molecules. Herein, an ecofriendly starch-based flocculant, i.e., 2,4-bis(dimethylamino)-[1,3,5]-triazine-6-starch, was synthesized via a preactivation-etherification strategy. The large molecular weight property produced by this method enhances intermolecular hydrophobic association, achieving complete phase separation all molecules from water residue-free for first time. Importantly, tertiary amine (LMTS) exhibits remarkable capacity over 1800 mg·g–1 dye wastewater, which is significantly higher than that polyacrylamide polyaluminum chloride flocculants. Furthermore, LMTS could be recycled pH adjustment, its structural stability ensured sustained reusability. This high-performance biomass-based offers green advance treatment.

Adsorption of Bisphenol A from Water Using Chitosan-Based Gels

Gels, Год журнала: 2025, Номер 11(3), С. 180 - 180

Опубликована: Март 5, 2025

The comonomer bisphenol A (BPA) finds applications in the plastics industry, where it is used production of polycarbonates, plastics, PVC, thermal paper, epoxy and vinyl ester resins, polyurethane. water, with which many these materials come into contact, one main sources human exposure to BPA. When ingested or touched, BPA can damage organs, disrupt endocrine immune systems, generate inflammatory responses, be involved genotoxic processes. Therefore, need develop effective techniques for removing from aqueous environments imperative. This paper provides a comprehensive review regarding removal focusing on performance adsorption mechanisms various adsorbents based chitosan composites. chemical physical factors, kinetics models governing process are also examined. outlines that, despite considerable progress absorption using gels, further research necessary assess efficacy treating real wastewater large-scale manufacture.
