Wastewater from industrial laundries is often difficult to treat because it usually presents high turbidity and chemical oxygen demand (COD). We studied several processes for the treatment of laundry wastewater which was provided by a hotel in south Gran Canaria, Spain. More specifically, we coagulation with iron (III) sulphate, Fenton, photo-Fenton biological (using biofilter, granular activated carbon, GAC, filtration). The Fenton produced large amounts sludge could not meet required standards water reuse use BF resulted complete removal COD removal. However, found that effluent did criteria reuse, thus GAC filtration post-treatment employed reduce acceptable levels. process alone reuse. estimated cost 1 m3 6.72 € 0.71 + GAC. life cycle assessment analyses were also performed revealed acquisition necessary reagents main contribution overall economic environmental costs both options, option notably cheaper. Additionally, this causes much lower impacts than photo-Fenton.

Sodium lauryl sulfate and its potential impacts on organisms and the environment: A thematic analysis

Emerging contaminants, Год журнала: 2023, Номер 9(1), С. 100205 - 100205

Опубликована: Янв. 14, 2023

Due to its ubiquitous presence in the environment and lack of a scientific consensus regarding environmental safety widely used anionic surfactant Sodium Lauryl Sulfate (CAS No: 151-21-3), systematic literature review thematic analysis was conducted. All studies about sodium lauryl sulfate (SLS) key databases were reviewed, with coding methods identify impact categories from SLS exposure without potential narration bias. Based on limited number SLS, there is empirical evidence this contributing toxicity at various concentrations (0.004–3509 mg L-1), aquatic organisms higher risk exposure. Furthermore, can elicit changes organismic processes equilibrium. Hence, further study compartments recommended monitor level pollution, understand behavior upon contact media, impacts flora fauna. Lastly, quantification should be done commonly consumer products potentially regulate use consequently curb pollution source.

From composite molecular structures to a multiplicity of supramolecular aggregates: The role of intermolecular interactions in biosurfactant self-assembly

Current Opinion in Colloid & Interface Science, Год журнала: 2024, Номер 70, С. 101792 - 101792

Опубликована: Фев. 9, 2024

Microbial biosurfactants are an attractive and promising class of molecules with the potential to replace oil-derived surfactants for formulation ecofriendly biocompatible products. In this review, we discuss literature findings, mostly reported in last decade, on self-assembly four main classes microbial biosurfactants, i.e., rhamnolipids, mannosylerythritol lipids, sophorolipids, surfactin. All them present composite molecular structures, characterized by different functional groups ionizable moieties a high conformational flexibility. Where possible, formation aggregate morphologies terms biosurfactant structure variation environmental parameters. We highlight how is regulated complex interplay between various intermolecular interactions, including H-bonds steric constraints, besides electrostatic hydrophobic interactions. For reason, show that common theoretical approaches amphiphile self-assembly, such as critical packing parameter, have limitations rationalizing predicting aggregation behaviour.

Development of carboxymethyl cellulose-based nanocomposite incorporated with ZnO nanoparticles synthesized by cress seed mucilage as green surfactant

International Journal of Biological Macromolecules, Год журнала: 2024, Номер 265, С. 130849 - 130849

This study aimed to enhance carboxymethyl cellulose (CMC)-based films by incorporating zinc oxide nanoparticles (ZnO NPs) and cress seed mucilage (CSM), with a view augmenting the physical, mechanical, permeability properties of resulting nanocomposite films. For first time, CSM was exploited as green surfactant synthetize ZnO NPs using hydrothermal method. Seven distinct film samples were meticulously produced subjected comprehensive array analyses. The findings revealed that incorporation CSM/ZnO-5 % improved physical films, demonstrating significant reduction in moisture content water vapor (WVP). Increasing concentration conjunction markedly decreased solubility nanocomposites up 56 %. containing CSM/ZnO showed higher tensile strength elongation at break values. UV absorption exhibited substantial rise addition NPs, particularly an increased presence CSM. thermal stability high improvement compared control sample. In light these results, CMC/CSM/ZnO-5 emerges promising candidate for biocompatible packaging material, exhibiting favorable characteristics.
