Fernández Sempere, Julio, Ruiz Beviá, Francisco, Salcedo Díaz, Raquel, García Algado, Pedro, García Rodríguez, Miriam Experiment VII. Ultrafiltration of PEG10000 with initial concentration = 10 kg/m3 and the module in 180º orientation URI: https://zebra.cpd.ua.es/vertice/20371 DOI: ISSN: Abstract: Video 9 from paper "BUOYANCY EFFECT ON THE ULTRAFILTRATION OF PEG10000. VISUALIZATION BY DIGITAL HOLOGRAPHIC INTERFEROMETRY", submitted to AIChe Journal, 2011. Video shows the first 3 min at the beginning of experiment and the first 6 min after the pressure ceased. The speed is increased three times during the UF process, whereas after the pressure ceases the speed is increased 6 times.
