Bio-Hybrid Membrane Process for Food-based Wastewater Valorisation: a pathway to an efficient integrated membrane process design
(2014-11-11)The food industry is by far the largest potable water consuming industry that releases about 500 million m3 of wastewater per annum with very high organic loading. Simple treatment of this stream using conventional ... -
Evaluation of thermal polarization and membrane characteristics for membrane distillation
(2014-11-11)The current PhD work emphasizes on various aspects of membrane distillation for approaching zero liquid discharge in seawater desalination. In broader sense, two themes have been discussed in detail: (i) correlation ... -
Preparation and characterization of hybrid nanosphers containing lipase for chiral drug biotransformation
(2014-11-11)Le Lipasi sono adatte a catalizzare reazioni di esterificazioni in solventi organici, mostrando elevata enantioselettività rispetto a quella mostrata nelle reazioni di idrolisi. Rispetto al grande quantitativo di Lipasi ... -
