Attachment of antimicrobial peptides to reverse osmosis membranes by Cu(i)-catalyzed 1,3-dipolar alkyne-azide cycloaddition
Bodner, Elias J.; Kandiyote, Nitzan Shtreimer; Lutskiy, Marina-Yamit; Albada, H. Bauke; Metzler-Nolte, Nils; Uhl, Wolfgang; Kasher, Roni; Arnusch, Christopher J. (Journal article; Peer reviewed, 2016)Biofilms are detrimental to many industrial systems that include reverse osmosis (RO) membranes. Accordingly, the development of surfaces with inherently bactericidal properties has attracted much research attention. ... -
Calculating expected effects of treatment effectivity and river flow rates on the contribution of WWTP effluent to the ARG load of a receiving river
Schwermer, Carsten Ulrich; Uhl, Wolfgang (Peer reviewed; Journal article, 2021)Concentrations of genetic markers for antibiotic resistance genes (ARGs) were measured in the effluents of three Norwegian wastewater treatment plants (WWTPs) and in a receiving river upstream and downstream of the discharge ... -
Combined membrane filtration and 265 nm UV irradiation for effective removal of cell free antibiotic resistance genes from feed water and concentrate
Krzeminski, Pawel; Feys, Edward; Anglès d'Auriac, Marc; Wennberg, Aina Charlotte; Umar, Muhammad; Schwermer, Carsten Ulrich; Uhl, Wolfgang (Peer reviewed; Journal article, 2020)The removal of cell free DNA (plasmids) carrying antibiotic resistance genes (ARGs) was investigated at bench-scale using ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO) membranes commonly applied in ... -
Effect of oxidation with coagulation and ceramic microfiltration pre-treatment on reverse osmosis for desalination of recycled wastewater
Myat, D. T.; Roddik, F.; Puspita, P.; Skillman, L.; Charrois, J.; Kristiana, I.; Uhl, Wolfgang; Vasyukova, E.; Roeszler, G.; Chan, A.; Zhu, B.; Muthukumaran, S.; Gray, S.; Duke, M. (Journal article; Peer reviewed, 2018)Oxidation and coagulation before ceramic microfiltration (CMF) greatly increases membrane flux, but is unconventional for reverse osmosis (RO) pre-treatment. Impacts to RO and the wastewater recycling scheme operating CMF ... -
Forekomst av antibiotikaresistensgener og fjerning av antibiotikaresistente E. coli i to norske avløpsrenseanlegg
Schwermer, Carsten Ulrich; Krzeminski, Pawel; Uhl, Wolfgang (Journal article; Peer reviewed, 2018)Effektiviteten av de ulike behandlingstrinnene for fjerning av antibiotikaresistente E. coli i avløpsvann fra to store avløpsrenseanlegg i Oslo ble undersøkt. Renseanleggene reduserer den totale mengden kultiverbare E. ... -
Integrative Review of Decentralized and Local Water Management Concepts as Part of Smart Cities (LoWaSmart)
Umar, Muhammad; Uhl, Wolfgang (NIVA-rapport;7058, Research report, 2016)An evidence-based assessment of decentralized and local water management concepts and how they relate to smart city concepts is presented. Decentralized water management is based on the principle of integrated water cycle ... -
N2 yields from monochloramine conversion by granular activated carbons are decisive for effective swimming pool water treatment
Skibinski, Bertram; Worch, Eckhard; Uhl, Wolfgang (Journal article; Peer reviewed, 2019)Inorganic chloramines (mono-, di- and trichloramine) are formed in swimming pool water from the unintended reaction of free chlorine with ammonia that is introduced by bathers. Monochloramine is of particular interest as ... -
Natural organic matter fractions and their removal in full-scale drinking water treatment under cold climate conditions in Nordic capitals
Krzeminski, Pawel; Vogelsang, Christian; Meyn, Thomas; Köhler, Stephan; Poutanen, Heikki; de Wit, Heleen; Uhl, Wolfgang (Journal article; Peer reviewed, 2019)Drinking water treatment plants (DWTPs) designed to remove natural organic matter (NOM) are challenged as concentrations of NOM in raw waters are increasing. Here, we assess seasonal differences in NOM quality and quantity, ... -
Pore diffusion limits removal of monochloramine in treatment of swimming pool water using granular activated carbon
Skibinski, Bertram; Götze, Christoph; Worch, Eckhard; Uhl, Wolfgang (Journal article; Peer reviewed, 2018)Overall apparent reaction rates for the removal of monochloramine (MCA) in granular activated carbon (GAC) beds were determined using a fixed-bed reactor system and under conditions typical for swimming pool water treatment. ... -
Removal of antibiotic resistant E. coli in two Norwegian wastewater treatment plants and by nano- and ultra-filtration processes
Schwermer, Carsten Ulrich; Krzeminski, Pawel; Wennberg, Aina Charlotte; Vogelsang, Christian; Uhl, Wolfgang (Journal article; Peer reviewed, 2018)The effectivity of different treatment stages at two large wastewater treatment plants (WWTPs) located in Oslo, Norway, to remove antibiotic resistant Escherichia coli from municipal wastewater was investigated. The WWTPs ... -
Utslipp av antibiotikaresistensgener med behandlet avløpsvann til resipienten
Schwermer, Carsten Ulrich; Uhl, Wolfgang (Journal article; Peer reviewed, 2018)Forekomsten av utvalgte markørgener for antimikrobiell resistens (AMR) i vannprøver tatt fra utslippet av tre norske avløpsrenseanlegg ble kvantifisert. 16S rRNA, Intl1 og Sul1 er de tre dominerende antibiotikaresistensgenene ...
