Graviranje kovin z vlakenskim laserjem s spremenljivo dolžino bliskov
Jernej Ortar, Peter Gregorčič, Matija Jezeršek
Diplomsko delo
Oznake: diplomske naloge;laserska ablacija;laserske obdelave;lasersko graviranje;nanosekundni vlakenski laser;laserski inženiring površin;nerjavno jeklo;
Lasersko graviranje predstavlja alternativo konvencionalnim metodam graviranja. Proces laserskega graviranja določajo različni parametri obdelave, kombinacijo katerih je potrebno izbrati tako, da z njimi dosežemo željeno končno stanje obdelovanca. V zaključni nalogi smo raziskovali vplive različnih ...

Oznake: enveloped viruses;phi6;SARS-CoV-2;virus inactivation;hydrodynamic cavitation;water decontamination;
The COVID -19 pandemic reminded us that we need better contingency plans to prevent the spread of infectious agents and the occurrence of epidemics or pandemics. Although the transmissibility of SARS-CoV-2 in water has not been confirmed, there are studies that have reported on the presence of infec ...

Removal of toxic metals from sewage sludge by EDTA and hydrodynamic cavitation and use of the sludge as fertilizer
Juan Francisco Morales Arteaga, Dominik Vodnik, Damijana Kastelec, Mojca Zupanc, Matevž Dular, Jernej Ortar, Marija Đurić, Anela Kaurin, Rok Mihelič, Domen Leštan
Izvirni znanstveni članek
Oznake: sewage sludge;toxic metals;EDTA;hydrodynamic cavitation;ReSoil®;soil fertilization;
Sewage sludge (SS) is rich in plant nutrients, including P, N, and organic C, but often contains toxic metals (TMs), which hinders its potential use in agriculture. The efficiency of removal of TMs by washing with ethylenediamine tetraacetate (EDTA), in combination with hydrodynamic cavitation (HC) ...

ǂThe ǂuse of hydrodynamic cavitation for waste-to-energy approach to enhance methane production from waste activated sludge
Mojca Zupanc, Barbara Brajer Humar, Matevž Dular, Jurij Gostiša, Marko Hočevar, Sabina Kolbl, Mario Krzyk, Lovrenc Novak, Jernej Ortar, Žiga Pandur, Blaž Stres, Martin Petkovšek
Izvirni znanstveni članek
Oznake: hydrodynamic cavitation;waste activated sludge;disintegration;viscosity;methane production;energy balance;
Anaerobic digestion in wastewater treatment plants converts its unwanted end product – waste activated sludge into biogas. Even if the process is well established, pre-treatment of the sludge can further improve its efficiency. In this study, four treatment regimes for increasing methane production ...
