Solvent extraction of sodium chloride from codfish (Gadus morhua) salting proce...
Ferraro, Vincenza; Cruz, Isabel B.; Jorge, Ruben Ferreira; Pintado, Manuela E.; Castro, Paula M. L.Codfish is worldwide mostly consumed salt-cured due to the highly appreciated sensory characteristics promoted by salt. During the salting process huge amounts of salted wastewater are generated – approximately 22% w/w of the codfish – carrying ca. 250 g/L of sodium chloride and ca. 10 g/L of organic compounds, namely proteins and free amino acids. In this study, the salt load of wastewater generated during the...
Valorisation of natural extracts from marine source focused on marine by-produc...
Ferraro, Vincenza; Cruz, Isabel B.; Jorge, Ruben Ferreira; Malcata, F. Xavier; Castro, Paula M.L.; Pintado, Manuela E.The wide chemical and biological diversity observed in the marine environment makes the ocean an extraordinary source of high added value compounds (HAVC) which can be employed in many applications. Minerals, lipids, amino acids, polysaccharides and proteins from marine sources have unique features and, surprisingly, their highest concentration is often found in parts of marine organisms that are commonly disca...
A membrane bioreactor for biotransformations of hydrophobic molecules using org...
Valadez-Blanco, Rogelio; Ferreira, Frederico Castelo; Jorge, Ruben Ferreira; Livingston, Andrew GuyThiswork reports the application of organic solvent nanofiltration (OSN) membranes to a membrane bioreactor for biotransformations (MBB). An organic solvent phasewas employed, allowing high substrate loadings and efficient product removal. The aqueous and organic phases were separated by an OSN membrane. The biotransformation of geraniol to R-citronellol by baker’s yeast was used as the model reaction, and n-he...
Aerobic biological treatment of wastewaters containing dichloromethane
Moura, Sandra C.; Jorge, Ruben Ferreira; Duque, Anouk; Boaventura, Rui AR; Castro, Paula MLBACKGROUND: Volatilization has been advanced as one of the predominant phenomena contributing to volatile organic carbon emissions from wastewater treatment plants (WWTPs). In this study, strategies for minimizing such air stripping losses when treating a liquid stream containing dichloromethane (DCM), aiming at decreasing the overall emission inventory from WWTPs, were investigated. RESULTS: System R1, consist...
Biological treatment of a contaminated gaseous emission from a paint and varnis...
Bastos, Filipe S.C.; Castro, Paula M.L.; Jorge, Ruben FerreiraA Vapour-Phase Bioreactor (VPB), namely a biotrickling filter, was scaled-up and operated in-situ for the treatment of gaseous emissions from a paint and varnish industrial plant. A microbial culture able to degrade the target compounds was enriched and a laboratory-scale VPB was established in order to evaluate the treatment's performance. The VPB presented removal efficiencies higher than 90% when exposed to ...
