Nanocomposite PVDF/TiO2 Photocatalytic Membranes for Micropollutant Removal in Secondary Effluent

Catalysts, Год журнала: 2024, Номер 14(2), С. 109 - 109

Опубликована: Янв. 28, 2024

In this study, a mixed-matrix method was used to prepare PVDF polymeric membranes with different amounts of TiO2 P25 photocatalyst embedded, which were employed in filtration processes the presence UV radiation (LED, peak emission at 375 nm) eliminate two aqueous micropollutants (MPs) as model compounds (venlafaxine and metoprolol). The obtained characterized gain insights into their texture, morphology, composition, other catalyst-related properties that could affect photocatalytic process. For purpose, N2 adsorption–desorption, contact angle, SEM-EDX, thermal analysis, FTIR, XPS, UV-vis DRS, PL spectroscopy used. Filtration tests carried out continuous mode using dead-end cell evaluate performance prepared removing selected MPs. Experiments performed both ultrapure water secondary effluent from municipal wastewater treatment plant. It found synthesized effectively remove target MPs water, achieving up 99% elimination. Such process decreased drastically removals below 35%. Carbonate/bicarbonate ions identified main scavenging substances. Thus, after partial removal carbonate/bicarbonate effluent, achieved above 60%.

Inactivation of waterborne Klebsiella pneumoniae with ozone to diminish the risk of hospital effluents using an absorption-based process

Journal of Water Process Engineering, Год журнала: 2023, Номер 57, С. 104732 - 104732

Опубликована: Дек. 30, 2023

In this work, the inactivation of waterborne antibiotic-resistance bacteria (ARB) Klebsiella pneumoniae (K. pneumoniae) has been evaluated to reduce health risk in hospital environments by using an absorption process employing ozone gas stream generated commercially available electro-ozonizers (MIKROZON® cell). The mass flow ranges from 0.026 0.047 mg min−1 depending on applied intensity (0.1, 0.25, or 0.5 A). results show that disinfection rate improves as increases and is significantly influenced organic matter content target liquid solutions. Specifically, log reductions 1, 4, 6 were achieved at end 180-min treatment urine when intensities 0.1, A applied, respectively. addition, logarithmic removal four Antibiotic Resistance Genes (ARGs) was investigated control spread antibiotic resistance through horizontal transfer processes. Logarithmic removals 5.43, 3.17, 3.04, 2.89 obtained for aac(6′)-Ib, blaTEM, blaSHV, blaKPC, respectively, during (0.047 gas). comprehensive comparison these ARGs with other technologies also provided. It can be concluded work presents promising have potential increase technology readiness level MIKROZON® generator, it demonstrates ability enhance highly effluents.
