The remediation of wastewaters contaminated with dyes (discharged mainly from industry) is very important for preserving environmental quality and human health. In this study, a new composite chitosan (CS)-based adsorbent combined activated carbon (AC) curcumin (Cur) (abbreviated hereafter as CS/AC@Cur) in three different ratios (12.5%, 25%, 50%) was synthesized the removal anionic [reactive black 5 (RB5)] cationic [methylene blue (MB)] single-component or binary systems. materials were completely characterized through Fourier transform infrared spectroscopy, scanning electron microscopy, Brunauer-Emmett-Teller analysis, X-ray diffraction. Specifically, decrease surface area CS/AC@ observed addition curcumin, 163 to 18 m2/g, all CS/AC@Cur derivatives. terms adsorption results, optimal derivative both RB5 MB found be CS/AC@Cur50%, providing 93% at pH 2.0 ± 0.1 54% optimum 9.0 due electrostatic attractions. Elovich pseudo-second-order kinetic model, correlation coefficient R2 >0.98, better tailored indicating that controlled by chemisorption. addition, Sips (Langmuir-Freundlich) isotherm model fitted calculated capacities 338 307 mg/g MB, respectively. thermodynamic analysis showed spontaneous endothermic procedure, chemisorption main mechanism. Reuse experiments efficiency retained high levels, while stability studies revealed retains its structural integrity, even extreme values. Finally, mixed solution investigated, competitive effect between dyes.

Enzyme-Assisted Wastewater Treatment in the Pharmaceutical Industry

Advances in environmental engineering and green technologies book series, Год журнала: 2025, Номер unknown, С. 399 - 424

Опубликована: Янв. 16, 2025

The pharmaceutical industry is a significant source of environmental pollution; the main concern being presence residues from products within water bodies. Methods used to treat wastewater traditionally involve physical and chemical processes, which lack desirable characteristics since they result in high costs, consume large amounts energy, produce toxic byproducts. use enzymes treatment appears as an effective sustainable alternative. For instance, oxidoreductases, lipases, proteases catalyze at mild conditions could split complex pollutants into less harmful forms. Enzymatic processes are friendly environment may minimize creation An illustration cases that have indicated successful pharmaceuticals, such diclofenac triclosan, be degraded using laccase. Some technical difficulties process need overcome: techniques enzyme immobilization, for setup costs.

Development of a Concept for Closing the Water Cycle in the Surface Treatment of Ferrous and Non-Ferrous Metals

Sustainability, Год журнала: 2025, Номер 17(5), С. 2212 - 2212

Опубликована: Март 4, 2025

This study examines the treatment of industrial wastewater generated during vibro-abrasive steel and Zn-Al alloy parts machining in a Polish metal-processing plant. The process uses grinding fluids, which are sent for disposal after becoming saturated with contaminants, incurring high costs. A two-stage filtration was investigated: an initial bag (pore size 5 µm) followed by low-pressure (4 bar) ultrafiltration polyacrylonitrile membranes (30 kDa cut-off). studies were carried out on laboratory scale cross-flow system using batch configuration. filtrate flux 0.116 mL min−1 cm−2 0.050 wastewater, respectively. Key physicochemical parameters, including turbidity, COD, TOC, analysed raw feed, retentate, permeate. Significant reductions contaminant concentrations achieved, comparable total efficiencies both wastewaters tested. anionic surfactants, phosphorus non-ionic surfactants ranged from 80% to almost 100%. complete removal suspended solids achieved. novelty this research lies applying flat-sheet treat vibratory ferrous non-ferrous materials recycle reclaimed water, has not been systematically explored previous studies. demonstrates potential membrane recycling, offering insights into environmentally friendly energy-efficient management wastewater.
