Optimization of Heterogeneous Photosensitized Oxidation for Winery Effluent Tre...
Silva, Mariana; Oliveira-Inocêncio, Inês; Martins, Rui C.; Quinta-Ferreira, Rosa M.; Gmurek, Marta; Nogueira, Anabela Gonçalves; Castro-Silva, SérgioIn this study, the heterogeneous photosensitized oxidation treatment of winery effluents was optimized using chitosan carriers immobilized with Zn(II) Phthalocyanine tetrasulfonic acid. The influence of main operating parameters such as initial pH, aeration flow rate, photocatalyst load, and concentration of the photosensitizer used in the photocatalysts’ preparation was investigated. Results for chemical oxyge...
Performance of polycarbonate, cellulose nitrate and polyethersulfone filtering ...
Abreu-Silva, Joana; Ribeirinho-Soares, Sara; Oliveira-Inocêncio, Inês; Pedrosa, Marta; Silva, Adrián M. T.; Nunes, Olga C.; Manaia, Célia M.Demineralized and disinfected waters may have very low microbial loads, requiring that large volumes of water are filtered to recover enough biomass for further analysis. Extended filtration periods, often interrupted by clogging, are a major limiting factor to concentrate samples' microbiota for further examination, besides hindering the work pace. In this study, we investigated the performance of three types ...
