V današnjem času se vse bolj zavedamo potrebe po energiji ter vpliva na okolje, ki ga povzročamo. V vodne vire vstopajo škodljive snovi, ki ogrožajo zdravje ljudi in negativno vplivajo na okolje. Te snovi je potrebno odstraniti ter s tem ohranjati čisto vodo, hkrati pa je potrebno stremeti k čim niž ...

wastewater sludge;porous layer;drying kinetics;shrinkage;thermography;
Convective sewage sludge drying is often carried out in belt dryers, where the air flow is directed through the layer. In such a configuration, drying air properties, as well as the structure of the layer and its homogeneity are key factors affecting the drying process. In the present work, these fa ...

cavitation;PVOH;microplastics;degradation;
Water-soluble poly(vinyl alcohol) (PVOH) is widely used in the textile and paper industries and in households as detergent pods. In addition to conventional microplastics, water-soluble PVOH poses an environmental threat because it is usually washed down the drain unnoticed and unobstructed. If not ...
