Sediments near industrial ports can be hotspots of fossil carbon accumulation

Marine Pollution Bulletin, Год журнала: 2025, Номер 213, С. 117636 - 117636

Industries near ports rely on fossil fuels and are likely to release carbon into nearby ecosystems. Release of hazardous compounds such as heavy metals polycyclic aromatic hydrocarbons can be directly coupled with the use those accumulated in port sediments. However, fractions sedimentary organic (SOC) at have not been investigated. We analyzed both concentrations radiocarbon isotope ratios SOC three types ports: fishery, steelmaking, multipurpose (where a ship terminal cement plant included). Results demonstrated clear distinction. The sediment steelmaking showed highest proportion (up 84%), while fishery consisted mostly modern carbon. had an intermediate, 36% contribution. Our findings suggest that sediments steel other industries hotspots carbon, potentially harming benthic

Bioremediation of Iron-Laden Steel Plant Effluent Using Bacillus Licheniformis: A Study of Isolation, Characterization, and Optimization

Journal of Lifestyle and SDGs Review, Год журнала: 2025, Номер 5(3), С. e04429 - e04429

Опубликована: Фев. 7, 2025

Objective: The objective of this study is to investigates the physicochemical characteristics and bioremediation potential Bacillus licheniformis on effluent from a steel manufacturing facility in Salem, India Method: A laboratory-based experimental approach was used assess licheniformis's capacity for production wastewater. Separating bacteria wastewater, describing its characteristics, evaluating how well it reduced iron levels were steps process. For chemical analysis, FTIR spectroscopy employed, microbiological identification, normal biochemical assays employed. Optimizing parameters including inoculum concentration, pH, temperature, incubation duration one procedures. Results Discussion: discovered that successfully decreased concentrations bringing them down 41.54 mg/L 23.08 mg/L. Significant alterations effluent's composition shown by suggesting organic contaminants had been degraded. greatest results obtained after optimizing settings, which included 48-hour at 30°C, pH 6, 6% concentration. These contribute more sustainable management techniques highlighting as viable agent treating iron-laden industrial Research Implications: research's practical implications indicate can be clean wastewater contains iron, especially sector, using techniques. might encourage ecologically friendly methods have an impact practices. Theoretically, work advances our knowledge role microbes play environmental biotechnology, namely reduction metals breakdown contaminants. Environmental engineering, treatment, microbial research are among fields potentially profit these discoveries.

Wastewater Remediation Treatments Aimed at Water Reuse: Recent Outcomes from Pilot- and Full-Scale Tests

Applied Sciences, Год журнала: 2025, Номер 15(5), С. 2448 - 2448

Опубликована: Фев. 25, 2025

Remediated water reuse is becoming vital for sustainable management, reducing the strain on freshwater resources, particularly in agriculture and industrial activities. Behind application irrigating crops processes, treated should be employed indirect direct potable use. In latter case, traditional approaches to wastewater treatment have been found inefficient, especially concerning biological contamination, persistent organic pollutants (POPs) and/or contaminants of emerging concern (CECs). Given that, according its origin foreseen use, each needs a specific treatment. A plethora new or improved materials, combinations different treatments check analyses are continuously developed tested at laboratory scale, first, necessary but not sufficient, step towards solution. Various innovative were pilot reduced number procedures applied full resulting significant production remediated desired quality. The present review focuses most recent outcomes obtained from remediation both scales discusses gaps which still hinder exploitation solutions advancements real-scale application.

Selective Manganese Precipitation via Neutralization and Ozone Oxidation under pH Conditions Similar to Steel Pickling Wastewater: Thermodynamic Assessment and Experimental XANES Evaluation

ACS Omega, Год журнала: 2025, Номер 10(17), С. 18085 - 18097

Опубликована: Апрель 25, 2025

Steel pickling wastewater contains valuable iron. Nonetheless, coexisting elements such as Mn need to be separated before Fe recovery. This work studies precipitation phenomena under a pH resembling steel and compares it that of the same conditions. A neutralization-oxidation approach was studied, whereby either NaOH or NH3 were used neutralizers O3 oxidizer. thermodynamic assessment indicated is more effective than for because can react freely with after addition, whereas may instead. Experimental data showed neutralization followed by oxidation results in formation different oxides, confirmed most neutralizer. Moreover, XRD XANES analyses state solids depends on neutralizer used. Conversely, thermodynamically experimentally observed depend entirely pH, being better NH3, = 1.5 maximum where remains dissolved. These insights suggest using method increases potential high enough while keeping low remain dissolved could an selective from wastewater.

Utilization of phosphogypsum in phenol removal from coking wastewater

Journal of Hazardous Materials Letters, Год журнала: 2023, Номер 4, С. 100089 - 100089

Опубликована: Окт. 22, 2023

The paper presents the results of application raw phosphogypsum as an adsorbent for preliminary treatment coke-chemical wastewater with initial concentration phenol 395 mg/L. Studies in batch mode have proved that removal is promoted by increasing dose and effluent temperature, optimal was found to be 5 g/L. adsorption kinetics follows a pseudo-first-order model, maximum capacity reaches 85 mg/g, which provides purification from at level 85-90%. process spontaneous endothermic. In column mode, flow rate 3 mL/min height fixed bed 15 mm dynamic reached 124 mg/g. obtained data indicate phosphogypsum, available huge quantities dumps phosphoric acid plants, can effectively used pretreatment phenolic before biological treatment.
