(1) Coagulation applied, as a unit process does not caused full reduction of organic compounds, and therefore it cannot be applied as a single unit process in the treatment of water containing NOM. (2) Analyzing the results involving the unit process (ultrafiltration) we found high efficiency of tur

Emulsion production using rotating membrane emulsification has been demonstrated. Emulsion droplets with average diameter of 81–567 mm and coefficient of variation (CV) in the range of 9.8–33.6% have been produced. In conclusion, this study showed that rotating membrane emulsification can be success

Membrane contactors have known recently an increasing interest [3]. They are reported for example for the preparation of emulsions (“membrane emulsification”) and for the preparation of precipitates. The membrane pores behave as parallel capillaries for the introduction of a phase A through the memb

• The clarified permeate juice presents titrable acidity, pH and TSS values comparable with those of untreated fresh lemon juice. • The results shows that an increase in pressure does not alter the permeate characteristics. • Permeate flux increase with the increased of both, pressure and feed flow

There was a tendency for increasing yield for reduced fat Prato cheese made from low concentration factor ultrafiltration when compared to cheeses made from non concentrated milk.

All the studied parameters influenced the permeate flux. An inter-relationship among them was observed. Crossflow velocity was the major variable responsible for flux increase, although enzyme treatment indicated also a positive effect. Transmembrane pressure did not show any effect in most cases, b

Transmembrane pressure was the major parameter responsible for the fouling layer formation, while the increase of crossflow velocity and the addition of enzyme contributed to diminish the polarized layer. At high transmembrane pressure values, enzyme treatment had more influence in polarized layer r
